Why frozen pipes cause damage

A frozen pipe does not always burst straight away. The split usually happens along the section of pipe where ice has formed. However, the leak may not show until the ice thaws and water pressure returns to normal. That is why a "frozen pipe" and a "burst pipe" event often overlap. You can have days of frozen taps followed by sudden flooding once the temperature rises again.

Which pipes are most at risk

Pipes in unheated spaces are the ones to watch. Think lofts, garages, cellars, and any run of pipework against an external wall. Similarly, outdoor taps and their supply pipes are also common failure points. This also includes pipework under kitchen or bathroom floors in an extension. That pipework was not insulated properly when it was built.

How to prevent frozen pipes

Insulate exposed pipework

The Met Office recommends making sure "all pipes in your roof space or loft, as well as pipes in other areas that may be vulnerable to the cold, are insulated". Foam pipe lagging is cheap, and a few hours with a tape measure and a hobby knife can cover most of a loft. In particular, don't forget the cold water tank itself, if you have one, and any pipework running through an unheated garage.

Keep some warmth in the house

If you are heading away for a break in winter, the Met Office advises that you "leave your heating on low". That's rather than switching it off completely. A background temperature stops pipes inside the building from reaching freezing, even while you are not there to notice a problem. Similarly, leaving loft hatches and cupboard doors under sinks open a crack can also help warm air reach vulnerable pipework.

Know where your stop tap is

Every home has a stop tap that shuts off the mains water supply. The Met Office's advice is blunt. Check it works every six months, and make sure everyone in the house knows where it is. You do not want to be searching for it for the first time while water is already spreading across the kitchen floor. Our guide on how to find your stop tap covers the likely locations room by room.

How to thaw a frozen pipe safely

If a tap has stopped running and you suspect a frozen pipe, don't panic. Avoid reaching for anything with a flame.

Step 1: turn off the stop tap first

Before you try to thaw anything, turn off the stop tap. If the pipe has already split under the ice, this limits how much water escapes once it thaws. As a result, it is far easier to do this now than after water starts coming through a ceiling.

Step 2: relieve the pressure

Next, open the nearby cold tap that the frozen section feeds. In particular, the Met Office notes that this "will relieve pressure on the frozen pipe" as it thaws, which reduces the chance of a split widening.

Step 3: apply gentle, even heat

Warm the pipe slowly. The recommended method is a hot water bottle held against the pipe, or towels soaked in hot water and wrapped around it. Work along the pipe from the tap end towards the blockage, rather than heating the middle first. Similarly, a hairdryer on a low setting, moved constantly along the pipe, is also a reasonable option if you have one to hand.

What never to do

Never use a naked flame or a blowtorch on a frozen pipe. The Met Office is direct about the risk: "direct heat may cause permanent damage to the pipes and could also lead to a fire in the home". However, older lead or soldered joints and nearby timber or insulation can ignite or melt long before the ice does.

Avoid electric heaters pointed directly at plastic pipework too. Similarly, even without a flame, concentrated heat can warp or scorch a pipe rather than thaw it evenly.

If the pipe has already burst

Sometimes the split only becomes obvious once the thaw begins, and water starts running from a joint or a crack the ice had hidden. If that happens, keep the stop tap off and mop up what you can. Mark your request as urgent if water is still escaping when you fill in our request form for an engineer.

Our guide on what to do in the first 10 minutes after a pipe bursts walks through the whole sequence. In particular, it covers what to do about electrics near the water.

A repair to a burst section of pipe usually needs a plumber rather than a DIY fix. This is particularly true if a wall or floor conceals the pipe. However, you can read more about the process on our burst pipe repair page.

Preparing for the next cold snap

Once a plumber has repaired a frozen pipe, it is worth checking why it froze. In particular, a section that froze once is likely to freeze again, unless it gets extra insulation. Rerouting it away from an external wall also helps.

Homes in cold, exposed parts of the region need to take this more seriously than most. In particular, rural and exposed properties covered by emergency plumber cover in Cannock often have outbuildings and long pipe runs. They should check loft and garage pipework before the first frost rather than after it. The same applies to homes around Codsall.

The same goes for older housing stock in the Wednesbury area. Original pipework there sometimes runs close to an external wall, with only plaster between it and the cold. As a result, a short check now is far cheaper than a burst pipe repair in January.

What a call-out usually includes

An emergency plumber's price usually has two parts, since the call-out charge and the labour or materials are billed separately. Cost-guide site MyJobQuote reports an average call-out of around £75, plus roughly £60 an hour. A typical completed job still lands near £200.

Other UK-wide guides give a slightly wider window, although the shape stays similar. BestBuilders puts a simple emergency call-out at £80 to £200. UK Plumber Spot's 2026 guide puts the first hour at £80 to £300. So, depending on the plumber and the time of day, expect the initial visit alone to fall somewhere in that £80 to £300 band.

These are national, outside-London figures. Checkatrade has also reported a single Wolverhampton-specific figure: a local range of £106 to £191, with an average of £142. That's useful context, however it comes from one source only. Treat it as a guide, not a promise of what any particular plumber will charge you.

Burst pipes: why the range is wider

A burst pipe is rarely a fixed-price job, since the cost depends heavily on where the pipe is and how hard it is to reach. For a simple, accessible repair, BestBuilders reports a typical range of £150 to £350. MyJobQuote's figure for a complete burst-pipe job, call-out included, sits at £150 to £270.

However, if the burst is behind a wall, under a floor or otherwise concealed, costs can rise. BestBuilders reports £400 to £1,200 for concealed repairs, and Home Repair Guide's 2026 UK figures put the same kind of job at £400 to £1,000. So expect a concealed repair to start from around £400 and often run to four figures. That's because reaching the pipe becomes a job in itself, before any repair can even start.

This is why plumbers avoid giving a fixed price over the phone for a burst pipe. Since nobody has seen the leak yet, they cannot know whether it's a five-minute fix or a job that needs the wall opening up.

Drain problems: a different cost picture

If your emergency is a blocked drain rather than a burst pipe, the numbers look different. However, Fantastic Services' 2026 cost guide still puts drain unblocking outside London at £80 to £250. UK Plumber Spot reports a similar £75 to £250 for rodding or jetting work.

For a single blocked toilet, sink or bath, MyJobQuote's guide is lower still. It reports around £50 to £70 for most fixtures, with a blocked toilet averaging £50 to £60. So a simple internal blockage is usually cheaper to fix than a burst pipe. That's simply because there's less to repair once the blockage is cleared. There's also less chance of the job needing anything opened up, since most internal blockages are reached from a fixture rather than the pipe run itself.

Why "fixed price" claims deserve a second look

You will see some plumbing websites advertise fixed prices, or promise no call-out charge at all. Be cautious of this, since every property, every pipe run and every blockage is different. A truly fixed price, quoted before anyone has looked at the job, is hard to stand behind.

A more honest approach is worth looking for instead. Although it takes a little longer, look for a plumber who explains their call-out charge upfront. They should give you a fair estimate once they've seen the job, and confirm the cost before starting any work.

What pushes the price up

A few factors often push emergency plumbing costs toward the top of these ranges, although not every job hits all of them:

• Calling out of hours, mainly late at night or on a Sunday, when call-out charges tend to be higher.
• A pipe or drain that's hard to access, such as one buried under flooring, boxed in, or in an external run.
• Extra damage from the leak itself, for example if water has reached electrics or soaked into a ceiling. That's a separate repair from the plumbing fault.
• The distance a plumber has to travel, since West Midlands towns further from a plumber's base may carry a higher call-out.

Getting a clear estimate for your situation

So much depends on what a plumber actually finds. The most reliable way to get a number for your specific problem is to describe it in detail, since a plumber can only price what they can picture. Say what you can see, when it started, and where the water or blockage is.

A request a quote submission with photos, where it's safe to take them, helps too, since it lets a local engineer give you a far more useful estimate than any national average ever could.

If your problem is a burst pipe specifically, our burst pipe repair page covers what that job typically involves. For anything else that needs a plumber urgently, the emergency plumber service is available in Wolverhampton, Walsall, Dudley and Cannock, among other West Midlands towns.

If the problem is a drain, not a pipe

Not every emergency is a burst pipe. If water is backing up rather than escaping, you're more likely looking at a blocked drain, and the cost picture above shows these jobs are often cheaper to put right.

Our blocked drains and drain unblocking pages explain the difference. While you're deciding which applies to you, our post on the warning signs of a blocked drain is a good place to start before you call anyone out.

The bottom line

Expect a call-out in the £80 to £300 range for most emergency plumbing visits in the West Midlands. The final bill depends on what needs fixing once the plumber can see it. Burst pipes generally cost more than drain blockages, and concealed pipework costs more still.

Treat any fixed price quoted before a look at the job with healthy doubt. Always get the job description in writing before work starts. If you're dealing with an emergency right now, the emergency plumber service covers the wider Wolverhampton area. Get in touch and describe what's happening, so a local engineer can give you a fair idea of cost.

What is a stop tap?

A stop tap, also called a stopcock, is the valve that controls water flowing into your home's plumbing system. Turning it off cuts the water supply to every tap, toilet and appliance in the property. That's because it's the single point everything runs through. That's exactly what you want during a burst pipe or a major leak.

It isn't something you use day to day. So unless you've had reason to look for it before, there's a good chance you've never seen it.

What does a stop tap look like?

Inside a home, a stop tap is usually a small valve on a section of pipe. Although it often has a round or lever-style handle rather than a wheel, most are a simple tap-like handle you turn by hand.

Older ones sometimes need a small key or a firm grip, because years of disuse can stiffen the mechanism. You'll generally find it set into the pipework close to where your water supply enters the building, rather than out in the open.

Where is it likely to be?

According to WaterSafe, the UK's national accreditation scheme for plumbers, the stopcock is usually under the kitchen sink or in a cupboard, garage or cellar. However, the Met Office's own guidance widens that list slightly. It notes that stop taps also commonly turn up in a downstairs bathroom or under the stairs. In practice, the most likely spots, in rough order of how common they are, are as follows.

• Under the kitchen sink, often tucked behind the pipework at the back of the cupboard.
• In an under-stairs cupboard.
• In a downstairs bathroom or cloakroom, near the pipework.
• In a garage, utility room or cellar, if your property has one.

If your home has had work done or been extended, check anywhere the original water supply pipe would have entered the building. That's usually the logical place for a stop tap to sit.

How to turn it off

Once you've found it, the process is simple, since turning the handle clockwise shuts off the water. WaterSafe's advice says exactly that: turn it clockwise to stop the flow, and it should take effect almost immediately. If the handle feels stiff, apply steady, firm pressure rather than force. Years without use can leave older valves stiff, and they can be more fragile than they look.

Test it before you need it

The best time to check your stop tap works is now, since testing it during an actual emergency wastes time you don't have. Find it, turn it off, then run a tap to confirm the flow has actually stopped. Turn it back on again afterwards. This does two useful things. First, it confirms you know exactly where it is. Second, it exercises a valve that might otherwise sit untouched for years and grow harder to move.

When you'd actually use it

The most common reason to reach for your stop tap in a hurry is a burst pipe. If that happens, turn off the water first, before anything else. This limits how much water escapes while you deal with the rest of the emergency. Our guide to what to do in the first 10 minutes after a pipe bursts walks through the full sequence. It covers when to switch off your heating and how to check for danger around electrics.

It's also worth turning your stop tap off before an extended trip away in winter. A frozen or burst pipe, while nobody is there to notice, can cause far more damage than one you catch immediately.

Why some stop taps are harder to find than others

Not every property is laid out the same way. That's part of why the guidance gives a list of likely spots rather than one single answer. In a house that's had a kitchen refit or an extension, the original pipework layout can change. The stopcock sometimes ends up boxed in behind new units, or moved to a different cupboard entirely. Flats and older conversions add another layer, since the stopcock can sit with plumbing shared from the building's history. As a result, it's worth checking utility cupboards and any hatch that gives access to pipework you don't normally see.

If your home came with a survey or a homebuyer's report, check whether it mentions the stopcock's location, since some surveyors note it. Failing that, a methodical search of the spots above, starting with the kitchen sink, covers most UK homes.

Why it's easy to forget where it is

A stop tap does nothing for most of the year, so it's an easy thing to lose track of. This is especially true if you've moved house recently, or someone else in the household dealt with it last time. That's exactly why it's worth treating this as a small maintenance task, rather than something to figure out under pressure. Find it, and note it somewhere memorable, such as a sticky note inside a nearby cupboard door. Make sure everyone in the household knows roughly where to look, too.

What a working stop tap protects you from

The value of a stop tap isn't just about burst pipes. It's also useful if you're fitting a new appliance, replacing a tap, or doing any work that involves disconnecting pipework. Since it lets you cut the supply cleanly first, it lets you isolate the water supply safely, rather than working on live pipes. Knowing it works, and works easily, means one less thing to worry about next time any of these situations comes up.

If you can't find it, or it won't move

If you've searched the usual places and still can't locate your stop tap, don't force it, even if you've found it but it won't turn. Forcing a stiff valve risks damaging it. A plumber can find and free a stiff stopcock quickly. It's a sensible job to sort out before you're relying on it in an emergency, rather than during one. The burst pipe repair service covers this kind of check. The emergency plumber service is there if you need help right now across Wolverhampton, Walsall, Dudley, Cannock, Bilston and Willenhall.

The bottom line

Your stop tap is most likely under the kitchen sink, in a cupboard, garage or cellar, a downstairs bathroom, or under the stairs. Find it today, and confirm it turns, since a valve that's never been tested is a risk in itself. Then you'll be ready if you ever need to shut off your water supply in a hurry. If you'd rather have a professional check it, or you're dealing with a leak right now, get in touch online. We'll arrange for a local engineer to help.

The good news is that the right first steps are simple, since you don't need any plumbing knowledge to follow them. This guide follows the order recommended by WaterSafe, the UK's national accreditation scheme for plumbers, and by the Met Office's own advice on burst pipes.

Step 1: Turn off the water at the stopcock

The single most important thing you can do is stop the water at its source. WaterSafe's advice is to locate your internal stopcock, since this is what controls the whole supply. It's usually found under the kitchen sink, or in a cupboard, garage or cellar. Turn it clockwise to stop the flow.

The Met Office gives the same locations, although it also notes the stopcock can turn up in a downstairs bathroom or under the stairs.

If you don't already know where yours is, find it today. Do this before you ever need it in an emergency. Searching for it while water spreads across your kitchen floor wastes minutes you don't have.

Once you find it, turn the handle firmly clockwise, and it should stop, or at least dramatically slow, the flow within moments.

Step 2: Switch off your heating

With the water isolated, switch off your central heating system next, since this stops your boiler trying to circulate water through a system that's now losing pressure. It also reduces how much water keeps moving through the affected pipe.

Step 3: Open your taps to drain the system

After the stopcock is off and the heating is down, open all your hot and cold taps. This releases the water still sitting in the pipes. It also reduces pressure in the system, which limits how much more can escape from the burst. The Met Office suggests saving some of this water in a bucket. It's still clean, so you can use it for flushing the toilet or washing your hands while the supply is off.

Step 4: Check for electrics before you touch anything

This step comes with a genuine safety warning. However careful you feel, if escaping water has reached sockets, switches or any electrical appliance, do not touch them. Both WaterSafe and the Met Office are explicit on this point. Switch off the affected circuit, or the whole property, at the fuse box. Don't risk an electric shock by touching wet electrics directly. If you're at all unsure, leave the electrics alone. Treat that part of the room as off-limits until a qualified person has checked it.

Step 5: Contain the water and protect your belongings

Once the water is off and the electrics are safe, turn your attention to limiting the damage. Towels, old bedding and buckets all help soak up or catch escaping water. WaterSafe also advises moving furniture and personal items away from the affected area. Use towels or boards to stop water spreading into rooms it hasn't reached yet.

Step 6: Call a plumber

With the immediate danger under control, it's time to get the pipe properly repaired. A burst pipe that's been isolated is stable, yet it isn't fixed. Leaving it isolated indefinitely means living without water to that part of your home. The burst pipe repair service covers this kind of job across Wolverhampton and the wider West Midlands. If you need a plumber for anything urgent beyond the pipe itself, the emergency plumber service is there too.

Step 7: Photograph the damage before you clean up

Before you start drying things out properly, photograph the affected area, since damaged flooring, furniture or ceilings are easier to prove now than later. If you need to claim on your home insurance, a clear record from the moment you found the damage makes that process much easier. Keep any damaged items where practical, until your insurer confirms they don't need to see them in person.

What if you can't find the stopcock?

If you genuinely cannot locate your internal stopcock and water is escaping fast, your priority shifts. Get people and pets away from the area. Protect electrics as above. Get towels and buckets down while you call for help. A plumber attending an emergency call-out can isolate the supply for you if you're unable to do it yourself.

Why a burst pipe happens in the first place

Understanding the cause helps you judge how urgent the situation is. Cold weather is a common trigger, since water expands as it freezes and can split a pipe from the inside. Often the crack only becomes obvious once the ice thaws and water starts flowing again. Old or corroded pipework is another common cause, particularly in older properties where a section of pipe has been in place for decades. High water pressure, a knock during building work, or a poorly fitted joint can all lead to the same result: a sudden, unplanned leak that needs an immediate response.

Because the cause varies so much, so does the fix. A frozen, split section of pipe in a loft might be a quick job, once the area is accessible. A corroded joint behind a bathroom wall is a bigger undertaking, since reaching it means opening up tiling or plasterboard first. Either way, the first ten minutes matter regardless of the cause. They determine how much water escapes before anyone starts the actual repair.

What not to do

A few instincts are worth resisting in the heat of the moment. Don't reach for electrics near standing water, even to switch off a light, until you've isolated the circuit at the fuse box. Don't try to patch the pipe yourself with tape or a makeshift clamp while it's still under pressure. It rarely holds, and it can delay the one thing that actually stops the leak: isolating the water supply. And don't assume a small trickle means a small problem. A slow leak from a hairline crack can still soak into floors and walls for hours, if the stopcock isn't turned off.

Different towns, same first steps

Whether you're in Wolverhampton, Walsall, Dudley, Cannock, Bilston or Willenhall, the first ten minutes look the same, since the steps don't change with the postcode. Stopcock off, heating off, taps open, electrics checked, damage contained. What changes is how quickly a plumber can reach you, and that's why knowing your own stopcock's location in advance is worth five minutes of your time this week.

After the water is off

Once the immediate danger has passed, it's worth thinking about why the pipe burst in the first place, particularly if the weather has been cold. Our post on what to do about wider emergency drain and pipe problems covers the broader picture, including who is responsible for fixing what. However, if the underlying issue turns out to be a blocked drain rather than a supply pipe, our guide to the warning signs of a blocked drain explains how to tell the difference.

Get help now

If you're dealing with a burst pipe right now, don't wait for it to get worse, since standing water rarely improves on its own. Request a callout online and describe what's happening, and we'll get you in touch with a local engineer who can take it from here.

Slow drains and gurgling pipes

Slow drainage is usually the first sign. Water sits in the sink or the shower tray for longer than normal, because a partial blockage is narrowing the pipe. Gurgling from a plughole or a toilet is the next clue. That narrowing traps air behind it, and the air forces its way back up the pipe.

A single slow drain often points to a local blockage near that fixture. If two or three drains slow down together, however, the problem usually sits further along a shared pipe.

What is actually causing the blockage

Water UK, the industry body for the water companies, studied 54 real sewer blockages. Wet wipes made up around 93% of the material inside them. Toilet paper and other flushable products, in contrast, made up less than 1% of the same waste. Water UK also estimates that sewer blockages happen around 300,000 times a year across the UK, at a cost of roughly £100 million.

That single fact explains why so many kitchen sinks block. Fat, wipes and other debris stick to the pipe wall. They narrow the gap bit by bit, until the pipe finally chokes. A kitchen sink that drains slowly for a month rarely fixes itself, and it usually ends in a full blockage.

Bad smells and rising water

A bad smell from a drain means something is rotting inside the pipe. Usually it is food waste, or a build-up of grease. Since bacteria break this material down slowly, the smell tends to worsen over several days rather than appear overnight.

Rising water in a toilet bowl after a flush is a stronger warning sign. It shows that waste cannot move past a blockage further down the pipe, so it pushes back the way it came. If this happens in more than one toilet, the blockage most likely sits in the main drain rather than one branch pipe.

Water coming back up

Water or waste coming back up through a drain or a toilet is a genuine emergency. At this point the pipe is full, and every extra flush or bath adds pressure to a system that already cannot cope. Stop using water in the property, and call a professional straight away.

A burst pipe is different again, and needs a different first move. Find your stop tap first — our guide to finding your stop tap shows what to look for — then follow our first 10 minutes after a burst pipe guide.

Damp patches near pipe runs

A damp patch on a wall or floor near a drain run can point to a cracked pipe rather than a simple blockage. Pressure builds up behind a blockage and finds the weakest point in the run. An old joint often turns out to be that weak point. Left alone, however, this kind of leak causes far more damage than the blockage that started it.

Whose drain is it, and who fixes what

Citizens Advice sets out a clear rule here. You look after the drains inside your own property boundary. The water company, however, looks after a lateral drain you share with a neighbour, once it leaves your land. That distinction matters, since it decides who you call first.

Road gullies work differently again. City of Wolverhampton Council maintains around 35,830 road gullies and cleans most of them once or twice a year. Residents can report a blocked gulley through the Love Clean Streets app. A blocked gulley outside your house, in short, is a council job rather than a drainage company's.

Simple checks before you call anyone

A few checks cost nothing and sometimes solve the problem outright. Try a plunger on the affected fixture first, since a simple air-lock or a loose clump of hair often clears with a few firm pushes. Follow this with a kettle of just-boiled water poured slowly down the drain, because heat alone can soften a young grease blockage.

Avoid pouring shop-bought chemical drain cleaner down an already slow drain. These products can sit in standing water for hours without reaching the blockage, and repeated use corrodes older pipework. If the plunger and hot water do not clear it within a day, stop trying home fixes and call a professional instead.

How professionals find the exact problem

A CCTV drain survey often gives the fastest answer. A waterproof camera travels down the pipe and records the blockage, a cracked joint or root ingress in real time, so the engineer knows exactly what tool the job needs before they start.

Once the cause is clear, high-pressure water jetting usually clears the blockage in minutes rather than hours. Jetting also cleans the pipe wall on the way through, which is why it tends to prevent a repeat blockage for longer than rodding alone.

Preventing the next one

Most kitchen blockages come from fat, oil and grease going down the sink while still warm. Because this waste solidifies as it cools, it sticks to the pipe wall and slowly narrows the gap. Let cooking fat cool in a container and bin it instead, and fit a simple mesh strainer over the plughole to catch food scraps.

Bathroom blockages, meanwhile, are usually hair and soap scum rather than fat. A cheap drain guard over the plughole catches most of it before it ever reaches the pipe. Since both habits take seconds, they are worth building into a normal cleaning routine rather than an emergency response.

The same pattern, street after street

The same wipes-and-grease pattern shows up across the area, since the housing stock and the drainage runs stay fairly similar from street to street. Find your own street in the list below for local access points.

• Blocked drains in Wolverhampton
• Blocked drains in Walsall
• Blocked drains in Dudley
• Blocked drains in Bilston
• Blocked drains in Wednesfield
• Blocked drains in Willenhall
• Blocked drains in Tettenhall
• Blocked drains in Codsall
• Blocked drains in Cannock

Requests also come from just outside the core towns. The coverage pages for Stourbridge, Bloxwich, Tipton and Wednesbury explain what's available in each area, even though it falls slightly outside the usual coverage area.

What to do next

Act on the early signs while you still can. A plunger or a kettle of hot water might still clear a minor blockage at this stage. Once you notice gurgling, a bad smell or water rising in more than one fixture, however, bring in a professional rather than keep trying home fixes.

A local engineer can diagnose and clear a blockage like this through the blocked drains service. If yours has already become a full blockage, drain unblocking covers exactly that job.

Request a no-obligation quote online and the engineer will talk you through the next step.

Why kitchen drains block so easily

Fat, oil and grease are the main culprits. Plumbers usually shorten that to FOG. Hot fat flows like water while it is warm, so it slips straight down the drain without trouble. However, it cools and hardens as it moves further down the colder pipe.

Since a thin layer of grease sticks to the pipe wall first, it soon traps other debris too. Food scraps, coffee grounds, and anything else that follows it down all get caught. Each layer narrows the pipe a little more, until eventually nothing gets through.

The scale of the problem nationally

Thames Water recently removed a 100-tonne fatberg from a sewer in Feltham, west London. It ran 125 metres long, formed from wet wipes congealed together with fat, oil and grease. That single fatberg shows how far this everyday habit can go, if nobody deals with it.

Water UK estimates that sewer blockages happen around 300,000 times a year across the UK. Clearing them costs roughly £100 million. Thousands of homes suffer sewer flooding every year because of blockages like these, since a choked sewer has nowhere else for the water to go but back up.

Daily habits that actually help

Never pour grease straight down the sink. Let it cool in the pan, then scrape it into the food waste bin instead. A sink strainer catches food particles before they reach the pipe. It takes seconds to empty after each use, too.

Scrape plates into the bin before washing up, even with a garbage disposal unit fitted. Run the hot tap for twenty or thirty seconds after washing greasy pans. The extra heat helps flush any leftover residue further down the pipe.

A weekly routine worth keeping

Once a week, boil a full kettle and pour it slowly down the kitchen drain. The heat softens any grease building up on the pipe wall, before it sets hard.

For a deeper clean, try baking soda and vinegar once a month. Pour half a cup of baking soda down the drain, then follow it with half a cup of white vinegar. Leave it to fizz for fifteen minutes, then flush the pipe with boiling water to clear the loosened residue.

What to avoid

• Chemical drain cleaners, since regular use corrodes older pipework over time
• Coffee grounds, which do not clean a pipe despite the popular myth
• Flour and other starchy foods, because they form a paste inside the pipe
• Eggshells, since they break into sharp pieces that catch other debris

What building rules say about grease

Approved Document H is the official guidance on drainage and waste disposal. It added specific rules on grease separators for commercial hot food premises. A domestic kitchen has no such separator fitted. That is exactly why good daily habits matter so much more at home.

Check the pack before it goes near the sink

Since 2017, EDANA, the trade body for the nonwovens industry, has promoted a front-of-pack "Do Not Flush" symbol on wipes that are not meant to go down a toilet or sink. Look for that symbol on any wipe packaging in your kitchen or bathroom cupboard.

If a product carries that symbol, bin it instead of flushing it. Wipes are the single biggest cause of blockages nationally, so this one habit change makes more difference than almost anything else on this page.

When prevention is not enough

Sometimes water still drains slowly, despite every habit on this list. When that happens, there is likely a deeper problem in the system. A CCTV drain survey finds the exact cause and location before any work starts, rather than leaving an engineer guessing.

Professional drain unblocking clears a stubborn or recurring kitchen blockage far more thoroughly than any DIY method can. A blocked sink that will not clear on its own usually needs an engineer on site, rather than another go with a plunger.

How a professional clears a set-hard grease blockage

Once grease sets hard, a plunger rarely shifts it on its own. An engineer instead uses high-pressure water jetting, which blasts the pipe wall clean rather than just pushing the blockage further along. This clears the fat completely, so the pipe stays open for longer afterwards.

A CCTV camera often goes in first on an older or recurring blockage. It shows the engineer exactly where the grease has built up and whether the pipe itself has any damage. That means the right tool goes to work straight away, instead of guessing at the problem from the sink end.

Simple checks before you call

A plunger is worth trying first, since it clears a simple air-lock in seconds. Push it firmly over the plughole and pump a few times, keeping enough water in the sink to form a seal. If that does not shift it, a bent wire coat hanger can hook out a shallow clump of hair or food waste.

Avoid mixing chemical drain cleaners with any of these methods. Standing chemicals can splash back once the blockage finally moves, and mixing products together sometimes creates dangerous fumes. Stop and call a professional instead, if the sink is still slow after a single attempt.

Kitchen drains across the area

Grease and wipes block kitchen drains in every town, and older terraced kitchens often share narrower, older pipe runs. Find your own town below for local notes on homes and drains.

What a CCTV drain survey actually is

An engineer feeds a small camera into the drainage system. It goes in through an existing access point. The camera travels through the pipe and records everything it sees. This finds blockages, cracks and root damage without any digging at all.

Why a standard survey misses this

A homebuyer's survey only looks at parts of a property a surveyor can reach and see. Drains sit underground, out of view, so they fall outside that scope entirely. Unless damp or subsidence is already visible above ground, however, a drainage fault simply will not get flagged.

Why 2011 changed who owns what

Before October 2011, many shared pipes counted as private sewers. Property owners along the route shared the repair bill between them. On 1 October 2011, though, ownership of most private sewers and lateral drains in England transferred to the water and sewerage companies. That single date still shapes who pays for what today.

That transfer only covers shared sewers and lateral drains. Citizens Advice is clear that you stay responsible for the drains inside your own boundary. You also remain responsible for the cost of maintaining any private or unadopted sewer that never transferred. A survey tells you which situation you are actually buying into.

Common problems a survey uncovers

Tree root ingress

Roots grow toward moisture, and a drain pipe is exactly that. Once a root finds a crack or a loose joint, it forces its way in. It then gradually chokes the pipe from the inside. Properties with mature trees nearby carry the highest risk.

Collapsed or cracked pipes

Older properties often still have clay or pitch-fibre pipework, and both degrade with age. A camera survey shows a crack, a break or a full collapse clearly. It does this long before any of it becomes visible above ground.

Displaced joints

Ground movement and traffic vibration can force pipe joints apart over time. A displaced joint lets waste leak into the surrounding soil. Left alone for long enough, that leak can eventually cause subsidence.

Wrong connections

Some older properties have surface water pipes wrongly connected to the foul sewer, or the other way round. A survey catches this kind of fault too. It shows up clearly on camera, even though nobody can see it from the surface.

What the rules say about access

Approved Document H sets out four types of drain access point: rodding eyes, access fittings, inspection chambers and manholes. It also sets maximum spacing between them. For example, a drain needs an inspection chamber within 22 metres of its start, and a manhole within 45 metres.

A survey engineer uses exactly these access points to run the camera through the system. If a property has too few of them, or none at all, that fact alone is worth knowing before you buy.

What a CON29DW search does not tell you

The CON29DW residential search is a standard part of most house purchases. Since it standardises the questions asked, every seller answers the same 25 set questions about the property's water and sewerage assets. It confirms whether the property connects to public sewers, and flags any recorded risk of internal flooding.

It does not show the physical condition of the pipes, though. A cracked pipe with no flooding history yet can pass a CON29DW search cleanly. It can still need thousands of pounds of work within a year or two. A CCTV survey is the only way to actually see inside.

Using the results at the table

A survey that finds a problem gives you real leverage before you exchange contracts. You can ask the seller to fix the fault, or negotiate the price down to cover it yourself. You can walk away too, if the damage turns out to be severe. Either way, you decide with the facts in front of you.

What a good survey provider gives you

Look for full HD footage you can keep and review later. Ask for a written report you can share with your solicitor, too. A good report explains any issue in plain English, and, since costs vary a lot by job, gives you a clear quote for any repair work it recommends.

At Emergency Plumber In Wolverhampton, we can pass your request for a pre-purchase drain survey to a local engineer. Ask them for the footage, a written report and a quote for any repairs the survey finds. If a survey does uncover damage, drain repairs such as pipe relining or full drain excavation can be requested, whichever the pipe actually needs.

What happens on the day

An engineer starts at the nearest manhole or inspection chamber. They feed the camera in and guide it along the full run, filming as they go. A monitor shows the footage live, so you watch the same picture the engineer sees.

How long it takes depends on the length and layout of the run, and the engineer can give you an estimate before starting. Afterwards, you get the footage along with a written summary of anything found. If the pipe turns out to be clear, that peace of mind alone often justifies the cost of the survey.

What a survey typically costs

Cost guides such as MyJobQuote and Precise Drainage put a typical domestic CCTV drain survey at roughly £85 to £350, with larger properties or a full mapping report towards the higher end. Treat any figure like this as a general guide rather than a fixed price, since the true cost depends on pipe length and access.

For plumbing costs beyond a drain survey, our guide to emergency plumber costs in Wolverhampton sets out typical UK price ranges for call-outs, burst pipes and drain jobs.

Recognising a real emergency

Not every fault counts as an emergency. Sewage backing up into the property is one that does. Water flooding from a drain, or several drains blocking at once, are two more. A strong sewage smell indoors, or waste in the garden, both need action right away too. A single slow drain, on the other hand, is rarely an emergency on its own; our guide to early warning signs of a blocked drain covers that stage instead.

Stop using water first

Stop every tap and appliance the moment you spot a serious problem. Do not flush toilets, run showers or start the washing machine. Every extra drop pushes the system further past its limit, since the blockage has nowhere left to send it.

A burst pipe needs the same quick action. Our guide to the first 10 minutes after a burst pipe covers the right order to follow.

Protect the property

Move furniture and valuables away from the affected area straight away. Roll up rugs and carpets where you can. Open a window too, since this lets sewage gases escape. Towels or a simple sandbag barrier can hold water back from spreading further.

Find the stopcock

Find your internal stopcock if water keeps flowing and you cannot stop it another way. It usually sits under the kitchen sink, or close to the front door. WaterSafe's advice for a burst pipe starts here: turn the stopcock clockwise, then switch off the heating and open the taps to drain the system down.

If you have never had to find yours before, our guide on how to find your stop tap shows exactly what to look for.

Keep clear of dirty water

Sewage carries bacteria that can make you ill. Keep children and pets well away from the area. Wear rubber boots and gloves if you must go near it, and avoid touching your face. Wash your hands well the moment you step away.

Photograph everything

Take photos and short videos of every affected area, once you have done what you safely can. Note the time the problem started, and write down anything damaged. Insurers almost always ask for this evidence later, so it pays to do it properly the first time.

What not to do

Chemical drain cleaners will not help here; they exist for minor blockages, not major failures. Never try to reach the main sewer under your property yourself. It connects to the public system, and reaching it yourself carries real danger. Ignoring the problem, in the hope it clears on its own, only makes things worse.

While you wait for the engineer

Clear access to any manhole or inspection chamber, since the engineer will need it fast. Note exactly where water is entering or backing up. Check with neighbours too, since a shared sewer fault behaves differently to one on your own property alone.

What an engineer checks first

An engineer starts by ruling out the simple causes first, since a quick fix is always the best outcome. They check the nearest access point for an obvious blockage, and test whether water moves at all once it is clear. If the fault sits further down the run, a CCTV camera goes in next to confirm exactly where the problem lies.

Only once an engineer confirms the cause does any digging or heavy equipment come out. This order matters, because it keeps the job as small and as quick as it can possibly be.

Who is responsible for what

Citizens Advice sets a clear line here. A lateral drain shared with a neighbour becomes the water company's job once it leaves your land. Inside your own boundary, though, the drains stay yours.

Road gullies work differently again. City of Wolverhampton Council maintains around 35,830 road gullies across the city. Residents can report a blocked one through the Love Clean Streets app. Approved Document H, meanwhile, says access points serving more than one property should stay reachable in an emergency, for example on a shared driveway.

What to have ready when you send a request

Have your address and postcode ready before you fill in the form, since this speeds up the whole process. Describe exactly what you can see and smell, and say when the problem started. Mention whether it seems to affect a neighbour too, since that can change what the job involves.

Keep your phone nearby afterwards. An engineer may need to call ahead to confirm access, or to check a detail before arriving. Because timing matters in a real emergency, a missed call can add unnecessary delay.

Frozen pipes: a common winter trigger

Cold weather is a frequent cause of burst pipes, since water expands as it freezes inside a pipe. The Met Office advises against touching electrics if escaping water reaches them; switch them off at the fuse box instead. Insulating exposed pipes before winter, meanwhile, is one of the cheapest ways to avoid this problem altogether.

Learn where your stop tap is before winter arrives. Then keep our burst pipe first-10-minutes guide close by too.

Getting help fast

Emergency drain services can send a local engineer for a problem like this, carrying CCTV cameras and high-pressure jetting equipment where the job needs it. If your problem is plumbing rather than drainage, emergency plumber and burst pipe repair cover that too.

After the immediate danger passes

Once the water stops and the area is safe, resist the urge to clean up straight away. Wait until the engineer confirms the pipe or drain is genuinely clear first, since a repeat backup can undo hours of cleaning in minutes. Air the property out well, and keep any damaged items aside until you have photographed them properly.

How drain rods work

Rods have cleared blockages for over a century. Flexible sections screw together, with different tips for different jobs. An operator pushes and twists the rod towards the blockage, hoping to break it up or push it clear.

Rods are cheap and simple, and need no power source at all. That makes them useful for a quick, accessible blockage. However, they usually reach no further than about 15 metres before they lose their force.

Where rods fall short

A rod can push debris further into the pipe instead of removing it. This sometimes hides a problem rather than fixing it, since the pipe still carries less water than before. An inexperienced user can also crack an old or fragile pipe by pushing too hard.

Because rods only push through the middle of a blockage, they rarely clean the pipe wall itself. Grease and scale stay behind, ready to build up again within weeks.

How high-pressure jetting works

Jetting uses a flexible hose fitted with a specialised nozzle. Water blasts out at high pressure. Some jets face forward to cut through the blockage. Others face back, pulling the hose through and flushing debris toward the access point.

A jetting rig reaches much further than a rod, often over 100 metres down a single run. Because the water pressure cleans the full pipe wall, not just the blockage itself, it clears many blockages faster than rodding alone.

The rules behind rodding access

Approved Document H sets out where drain access points should sit. Access should sit at or near the head of each drain run. It should also sit at every bend, gradient change or junction along the way. A rodding eye, defined in the same document, is simply a capped extension of the pipe.

These access points exist for normal rodding. Rodding does not have to follow the direction of flow. The rules never had mechanical jetting equipment in mind, though modern jetting hoses still use the same points to enter the pipe.

The industry code that governs jetting

The Water Jetting Association publishes a single code of practice covering safe jetting work. Its 2026 Black Code brings together three earlier codes: the original Blue Code from 1982, the Red Code for drains and sewers from 2002, and the Purple Code from 2024.

That code covers hose inspection, testing, and the safe use of jetting equipment. A badly maintained hose can fail under pressure, so following it matters for the operator's safety as much as the customer's pipe.

When each method actually suits the job

Rods still suit a simple, visible blockage close to the access point, or a situation where jetting equipment is not available on the day. Very minor slow drainage sometimes clears with rods alone, without any need to escalate further.

Jetting suits almost everything else. Think fat and grease build-up, tree root ingress, a full blockage, or a pipe that keeps blocking again and again. Commercial properties, in particular, benefit from the deeper clean jetting gives over a rod alone.

Why jetting often works better than rods

Jetting clears blockages that rods cannot reach at all, since it cleans the full pipe wall rather than just pushing a hole through the blockage. It often finishes the job faster, too. Because the pipe stays cleaner afterwards, the same blockage is less likely to come back.

On a typical drain jetting call-out, the engineer checks the access points first, then uses a camera to confirm the exact location if needed. They fit the right nozzle for the job and clear the blockage. You can ask for another camera pass afterwards to check the result.

What jetting typically costs

Cost guides such as Fantastic Services and MyJobQuote put professional drain jetting at roughly £70 to £175 outside London, against £80 to £250 for general drain unblocking work. Treat these as typical ranges rather than a fixed price, since the length of pipe and the severity of the blockage both affect the final cost.

Weighing up the cost

DIY rods look cheaper at first glance. However, an incomplete clear often means calling a professional anyway once the blockage returns. Pipe damage from over-enthusiastic rodding can cost far more to repair than the original job. Professional jetting, in contrast, tends to work out cheaper over a full year.

For other plumbing emergency costs, see our guide to emergency plumber costs in Wolverhampton.

If you suspect pipe damage is behind a recurring blockage, a CCTV drain survey confirms whether drain repairs are actually needed before you commit to further work.

Nozzle choice matters too

A root-cutting nozzle suits a pipe with tree root ingress, while a flat-fan nozzle works better against grease and scale on the pipe wall. A penetrating nozzle, meanwhile, pushes through a solid blockage before the main clean begins. Picking the wrong nozzle wastes time on site, so an experienced operator checks the pipe first, then chooses accordingly.

Signs you need jetting, not rods

A drain that blocks again within a few weeks of clearing usually needs jetting rather than another round of rodding. The same goes for a kitchen drain with a slow, greasy smell, since that points to a coating on the pipe wall rather than a single lump of debris. Our guide to preventing blocked kitchen drains covers the daily habits that keep this from building up in the first place.
