A radiator leaking from the bottom is often caused by a leaking valve, a loose valve tail nut, or a joint in the pipework just below. In some cases, the radiator itself has corroded from the inside and developed a pinhole leak. Water can also run down from somewhere else and simply drip from the lowest point.

Corrosion and pinholes in the radiator body

Over time, the water inside a heating system can cause steel radiators to rust from the inside. Sludge often settles along the bottom of the radiator, and that is where corrosion can be at its worst. Eventually a tiny pinhole may form, letting water weep out slowly.

You may see a rusty mark, a damp patch along the lower edge, or a small bead of water that keeps coming back. A pinhole in the body often suggests the radiator is coming to the end of its life. Patching it rarely lasts, so replacement is usually the more sensible option.

Valves, tail nuts and pipe joints

Many leaks that seem to come from the bottom of a radiator actually start at the valves on each end. The valve tail screws into the radiator, and a nut joins it to the valve. If the seal on the tail has failed, or the nut has worked loose, water may drip from underneath.

Pipe joints below the valves can leak too. Compression fittings can weep if the pipe has moved, and old soldered joints can corrode. Water from these points often runs down the pipe and drips onto the floor, so it can look as if the radiator itself is leaking.

When the water comes from somewhere else

Water tends to travel before it drips. A leak from a pipe higher up, or from a valve spindle on the same radiator, can run along the underside and collect at the lowest corner. Condensation on cold pipes can also gather and drip, especially in cooler rooms.

Drying the radiator, valves and pipes with a cloth, then holding dry kitchen roll against each joint, can help show where water first appears. A bowl or towel underneath will protect the floor while you look.

If water is near sockets, plugs or other electrics, keep clear and do not touch anything wet. Only switch off at the consumer unit if it is dry and safe to reach, or ask an electrician for help.

Repair, replace or get help

A loose nut or worn valve seal can often be repaired. Corrosion in the radiator body usually means a new radiator. Many homes have a sealed heating system that holds water under pressure, so draining down or opening joints is not a job to guess at. You can find out more about help with a leaking radiator and how the plumbing side is checked. Any work on the boiler itself needs a Gas Safe registered engineer.

A concealed toilet cistern usually leaks because a seal, valve or connection inside the boxing has worn or worked loose. Common culprits are the water supply connection, the fill valve, and the flush pipe seal where water passes into the pan. Because the cistern sits behind a panel or wall, a leak can go unnoticed for some time.

How concealed cisterns are hidden

A concealed cistern is fitted inside a frame or stud boxing, with tiles or panels over the front. You only see the flush plate on the wall and the toilet pan below. Wall-hung toilets often use a steel frame that carries both the cistern and the weight of the pan.

Most designs let you reach the inside through the flush plate opening. Removing the plate gives access to the valves on many models. Some also have a separate access panel.

Where the water may be coming from

The inlet connection, where the supply pipe joins the cistern, can drip if a fitting has loosened or a washer has perished. The small isolation valve nearby can also weep. The fill valve can fail just as it does in an exposed cistern, overfilling or leaking at its base.

A worn flush valve seal may let water trickle into the pan. A more serious leak can come from the flush pipe or outlet seal that links the cistern to the pan. If that seal is worn or poorly fitted, water may escape behind the panel each time you flush.

Condensation is another possibility. Cold water in the cistern can cause moisture to form on its outer surface, especially in a warm, steamy bathroom. Insulation helps, but it can still add to damp in the boxing.

Signs of hidden moisture behind panels

Because the water is behind a wall, you often see the effects before the leak itself. Look out for:

• staining or discolouration on the boxing or nearby walls
• tiles that sound hollow, crack or come loose
• swollen or bubbling boards on boxing or furniture panels
• a musty smell that does not clear
• water pooling at the base of the wall or around the pan

None of these proves the cistern is to blame, as water can track from pipes elsewhere. But they are good reasons to have it checked.

Getting a concealed cistern inspected

Please do not start removing tiles or breaking into boxing yourself. It can damage the frame, the cistern or the pipework, and it may not be needed at all. A plumber will usually start by taking off the flush plate or access panel and checking what can be seen from there. You can find out more about help with a leaking concealed cistern and how faults like these are traced.

If water is clearly escaping, turn off the isolation valve or the stopcock if it is safe and you know where it is. Keep clear of any wet electrical fittings.

Yes, a faulty toilet flush valve can often be repaired, usually by replacing the worn seal or washer at its base. If the valve body is cracked, warped or no longer made, replacing the whole valve may be the better fix. The right choice depends on the type of valve, the make of toilet and how easy it is to reach.

Drop valves and siphons work differently

Most modern toilets use a drop valve. When you press the button, a plug lifts off a hole in the bottom of the cistern and water drops straight into the pan. A rubber seal around that plug stops water leaking when the toilet is not in use.

Many older toilets use a siphon instead, worked by a lever handle. Inside the siphon is a flexible plastic diaphragm, sometimes called a flap valve, which lifts water up and over to start the flush. When the diaphragm splits, you may need to pump the handle several times.

Both types wear with age, but the faults look different. A drop valve tends to leak into the pan, while a worn siphon diaphragm usually makes flushing unreliable.

Replacing the seal or the whole valve

On many drop valves, the seal at the base can be swapped without removing the rest of the valve. The valve cage is often unclipped or twisted out, the old washer is removed, and a new one is fitted.

If the valve body is cracked, the plastic has become brittle, or limescale has damaged the sealing surface, a new seal may not hold for long. Fitting a complete new flush valve is often more reliable. Matching the part to the make and model matters, because seals and valves come in many sizes and shapes.

Dual-flush buttons and cables

Dual-flush toilets have two buttons, one for a short flush and one for a full flush. The buttons are linked to the valve by rods, a cable or sometimes an air tube. If a button feels loose, sticks down, or only one flush works, the fault may lie in the linkage rather than the valve.

Cables can stretch or snap, and button assemblies can crack. These parts are often brand-specific, so it helps to know the make of your toilet before ordering anything.

When access makes the job harder

Reaching the flush valve is not always simple. On a close-coupled toilet, the cistern sits directly on the back of the pan. The valve is often held in by a large backnut underneath, so changing it can mean turning off the water, emptying the cistern and lifting it off the pan.

Concealed cisterns behind panels add another layer, as the valve is reached through the flush plate opening. If you would rather not take this on, our cistern and flush valve repairs cover drop valves, siphons and dual-flush mechanisms. A plumber can also check the fill valve at the same time, as parts often wear out together.

If your flush valve is leaking or playing up and you are in Swindon, Emergency Plumber Swindon is happy to talk it through. Give us a call on 01793 569521.

A toilet cistern that keeps filling with water is usually losing water somewhere, or its fill valve is not shutting off properly. Common causes are a worn flush valve seal letting water seep into the pan, or a float set too high so water runs away down the overflow.

What “ghost flushing” sounds like

Some people notice the cistern starting to refill by itself at intervals, even when nobody has used the toilet. This is sometimes called ghost flushing. It often happens when water slowly escapes from the cistern into the pan. Once the level drops far enough, the float falls and the fill valve opens to top it up again.

A constant trickling refill is slightly different. Here the fill valve may never fully close, so a thin stream keeps running in.

Why the cistern keeps topping itself up

The fill valve is the part that lets fresh water into the cistern. It is controlled by a float, which rises with the water and shuts the valve off at the right level. If the float is set too high, or it sticks on its arm or rod, the valve can stay open. Grit and limescale inside the valve can also stop it sealing.

If the water level sits above the top of the overflow, the extra water simply drains away and the valve keeps feeding more in. This overflow may run into the pan or out through a pipe on an outside wall.

The other common cause is the flush valve seal at the bottom of the cistern. When this rubber washer wears or gets grit under it, water slips past into the bowl. You may see faint ripples running down the back of the pan. This slow loss is what makes the fill valve wake up and refill every so often.

Checking for a leak and wasted water

WaterSafe suggests a simple toilet paper test for a leaky loo. Dry the back of the pan and lay a sheet of toilet paper across it. If the paper gets wet before you flush, water is likely trickling through from the cistern.

If your home has a water meter, a cistern that refills on its own can quietly push up your usage. A small, steady leak runs day and night. You could also lift the lid and see whether the water is close to or above the overflow. Try not to bend the float arm or force parts, as plastic fittings can snap.

When a plumber should investigate

It makes sense to get help if the cistern keeps refilling after simple checks, if the overflow is running outside, or if parts look cracked or heavily scaled. A plumber can check the fill valve, float setting and flush valve seal together, as one fault can hide another. Our cistern repair service covers faults like constant refilling and worn internal parts. Sometimes a new seal is enough, while older valves may be better replaced.

A slow drip from an ordinary overflow pipe is usually not an emergency, but it is a sign that something needs fixing soon. It becomes more urgent if the flow is heavy, the overflow is blocked or water is coming into your home. Water from a hot water cylinder’s safety pipe is a different matter and needs prompt professional help.

When a Dripping Overflow Can Wait a Little

Most overflow drips come from a toilet cistern or a cold water cistern in the loft. The overflow pipe is there to carry extra water safely outside, so a slow drip means the system is working as designed.

In this case, you usually have time to arrange a visit at a sensible time. It is still worth acting within a few days. A small leak can grow, it wastes water, and in cold weather a constant drip may freeze and cause icy patches outside.

Signs It Needs Urgent Attention

Some overflow problems need faster action. A heavy, continuous flow from the pipe suggests the valve may have failed badly, and the cistern could struggle to keep up.

A blocked or frozen overflow is another concern. If water cannot escape through the pipe, the cistern may fill until it spills over the top. In a loft, this can lead to water coming through the ceiling below.

If you see bulging plaster, spreading stains or water dripping from a ceiling, treat it as urgent. If it is safe and you know where it is, turn off the stopcock to slow the flow. Keep clear of any wet light fittings or switches and get an electrician to check them.

A Cylinder Safety Pipe Is Different

Not every pipe that drips outside is a cistern overflow. Homes with an unvented hot water cylinder have a safety discharge pipe. This often runs through a small open funnel called a tundish, then out to a drain or an outside wall.

Water or steam from this pipe can signal a fault with the cylinder’s safety controls. It should never be blocked or capped, as it is designed to release pressure safely. Keep well away from any hot water or steam, and contact an appropriately qualified professional urgently.

If the cylinder or boiler is involved, follow the advice of the qualified engineer who attends. Do not try to adjust or repair any part of an unvented system yourself.

Getting the Right Help

If you are unsure what kind of pipe is dripping, look at where it comes from. A pipe from the loft or a toilet is usually a cistern overflow, while a pipe near the airing cupboard may be linked to the cylinder.

For ordinary cistern overflows, a plumber can find the cause and fix the valve. You can learn more about help with a leaking overflow pipe on our service page. If you are worried about water damage, our emergency plumbing page explains what to do next.

Yes, a faulty float valve is one of the most common reasons water runs from an overflow pipe. If the valve does not shut off when the cistern is full, water keeps coming in and the extra spills out through the overflow. The good news is that these valves can often be repaired or replaced fairly simply.

How a Float Valve Controls the Water Level

A float valve, sometimes called a ball valve, lets water into a cistern and stops it at the right level. Older types have a plastic or copper ball on the end of a metal arm. As the water rises, the ball floats up and pushes the arm, which closes the valve.

Modern toilets often use a fill valve instead. This works on the same idea, but the float sits on a vertical post or inside a small cup next to the valve. When the float reaches a set height, the valve shuts and the flow stops.

If any part of this system fails, the valve may stay partly open. Water then keeps trickling in until it reaches the overflow.

What Goes Wrong Inside the Valve

Inside most float valves is a rubber washer or a flexible diaphragm. This presses against a small opening to stop the water. Over time it can wear, harden or split, and water may then seep past even when the float is up.

A split float is another cause. If water gets inside the ball, it sinks lower and no longer lifts the arm high enough to close the valve. Grit, scale or tiny bits of debris from the pipes can also lodge in the valve and stop it sealing.

Water pressure can affect how well a valve shuts off too. A valve not suited to the pressure in your home may struggle to close fully.

Toilet Cisterns and Loft Cisterns

In a toilet cistern, a failing fill valve often shows as a faint hissing sound or a constant trickle into the pan. In a loft cold water storage cistern, the first sign is usually a drip from a pipe high on an outside wall.

Loft cisterns can be harder to check, as they are often in tight spaces with poor lighting. It is best to leave inspection to someone who can reach it safely.

Repair or Replace the Valve?

If the valve is fairly new, a plumber may be able to fit a new washer or diaphragm, clear out debris or adjust the float height. A split float can sometimes be swapped on its own.

If the valve is old, worn or a type that is hard to get parts for, replacing the whole valve is often more reliable. A modern valve may also be quieter and easier to adjust. You can find out more about getting a dripping overflow pipe fixed on our service page.

If you suspect a float valve is behind your overflow problem, Emergency Plumber Swindon can check it and explain what is needed. Call 01793 569521 for help in Swindon.

Water usually drips from an overflow pipe because a cistern somewhere in your home is filling higher than it should. This is often linked to a faulty float valve or inlet valve that is not shutting off properly. The first job is to work out which cistern the pipe comes from.

What an Overflow Pipe Is For

An overflow pipe is a safety outlet. If a cistern fills too high, the extra water runs out through the overflow instead of spilling over the top and into your home.

Water Regs UK explains that every cold water storage cistern must have an overflow pipe that discharges somewhere safe and easy to see. That is why many overflow pipes poke out of an outside wall, so a drip will catch your eye. In other words, the dripping pipe is doing its job and warning you of a problem.

Which Cistern Could Be Causing It

Many homes have more than one cistern, so the position of the pipe can give a clue.

A pipe just outside a bathroom wall often comes from a toilet cistern. In many modern toilets, the overflow runs inside the pan instead, so you may see a thin trickle running down the back of the bowl rather than outside.

A pipe high up near the eaves may come from the cold water storage cistern in the loft. This tank feeds some taps and the hot water cylinder in older systems.

Some homes with an open-vented heating system also have a smaller feed and expansion cistern in the loft. This tops up the heating water, and it has its own overflow too. If you are unsure which one is the source, a plumber can trace it.

Why the Water Level Rises Too High

The most common cause is a valve that lets water in but does not close fully. This can happen when a washer wears, a float gets stuck or damaged, or grit stops the valve sealing. The float arm may also be set too high, so the water reaches the overflow before the valve shuts off.

Less often, a problem with a hot water cylinder or heating system can push water back into a loft cistern. This is harder to spot and may need a closer look.

Why It Is Worth Getting It Checked

A small drip may not seem serious, but it can waste a lot of water over weeks and months. If you are on a water meter, it can add to your bills. Constant water can also stain walls, damage brickwork or create icy patches on paths in winter.

A plumber can find the source, adjust or repair the valve, and check the cistern is in good condition. Our page on overflow pipe repair in Swindon explains how this is usually handled.

In most UK homes, the inside stopcock is the property owner’s responsibility to repair or replace. The outside stop valve, often found under a small cover near the boundary, is usually looked after by the water company. The exact split can vary, so it helps to check before arranging any work.

The Inside Stopcock Belongs to the Property

The inside stopcock is the valve you use to turn off the water inside your home. It is part of your internal plumbing, so if it leaks, sticks or will not close, the owner is normally expected to arrange the repair.

This is why it is worth testing your stopcock now and then. If it is stiff or weeping, getting it sorted early means it will work when you really need it. A plumber can service it or fit a new valve if needed.

The Outside Stop Valve and the Water Company

The outside stop valve, sometimes called a stop tap, is usually in a small chamber under a cover on the path, driveway or pavement. In many cases it is owned and maintained by the water company. In Swindon, the water supplier is Thames Water.

Thames Water explains that you should only use the outside stop valve in an emergency and should always have a working inside stop valve rather than relying on the outside one. If the outside valve is leaking, broken or cannot be found, contacting your water supplier is usually the first step.

When the Boundary Is Not Clear

Not every property follows the same layout. Some outside valves sit inside the garden rather than on the pavement. Older homes, flats and terraced houses may also have shared supplies, where one pipe or valve serves more than one property.

In these cases, responsibility can be harder to work out. It may depend on where the valve sits, who it serves and what your deeds or lease say. If you are unsure, your water supplier can usually tell you who looks after a particular valve. It is best not to assume, and never dig up or alter a shared valve without checking first.

Landlords, Tenants and Stopcocks

If you rent your home, the landlord is usually responsible for fixing a faulty stopcock, as it forms part of the water supply pipework. Tenants should report the problem to their landlord as soon as possible and avoid carrying out repairs themselves unless their tenancy agreement allows it.

It still helps tenants to know where the stopcock is and whether it turns, so they can act quickly if a pipe leaks. Landlords may want a plumber to check that it works properly between tenancies. More details about fixing or renewing a faulty stopcock can be found on our service page.

If you own your home or let one out and need a stopcock checked, Emergency Plumber Swindon is happy to take a look. Call us on 01793 569521 and we can talk through what is needed.

A seized stopcock can sometimes be freed and repaired, especially if the valve body is still in good condition. If the valve is badly corroded, will not close fully or is very old, replacing it is often the safer choice. Either way, it is best not to force it yourself.

Why Stopcocks Seize Up

Most stopcocks are hardly ever used. They might sit untouched for years until the day you really need them, and by then the spindle may have stuck in place.

Limescale is a common cause in hard water areas. Mineral deposits build up around the moving parts and lock them together. Corrosion can do the same, especially on older brass or iron valves where the metal has started to break down.

Age also plays a part. Gland packing can harden, washers can stick to their seat, and the threads on the spindle can wear or bind. A valve may turn a little and then stop, or not move at all.

Why You Should Never Force a Stiff Valve

When a stopcock will not turn, it is tempting to use more strength, a wrench or a long lever for extra grip. This can cause real damage. The spindle can snap, the valve body can crack, or the head can shear off, leaving water you cannot control.

The risk is higher in older homes. If the stopcock sits on old lead or iron pipe, twisting the valve can put strain on the pipe itself. This may create a new leak at a joint that was fine before, or split a weak section of pipe.

If you need to stop the water urgently and the stopcock will not move, leave it alone and get help from a plumber or your water supplier.

Repair Options a Plumber May Consider

In some cases, a plumber can free a seized valve carefully without damaging it. Once it moves again, it may be serviced so it turns more easily.

Some older-style stopcocks can be repaired by renewing the gland packing or replacing the inner washer. This can stop weeping around the spindle and help the valve shut off properly again. Whether this works depends on the type of valve and its condition.

When Replacement Makes More Sense

Replacement is often recommended when the body is heavily corroded, when the valve still lets water through after being closed, or when parts are no longer available. Many homeowners choose to upgrade to a quarter-turn valve, which is easier to open and close quickly in an emergency.

Changing a stopcock usually means the water supply has to be isolated first, which is normally done at the outside stop valve. A plumber can check the pipe on both sides and make sure the new valve is fitted securely. You can find out more about repairing or replacing a stuck stopcock on our service page.

If your stopcock is stuck and you are not sure whether it can be saved, Emergency Plumber Swindon can assess it and explain your options clearly. Call 01793 569521 to talk it through with our team in Swindon.

A stopcock usually leaks because the packing around the spindle has worn, a joint on either side has loosened, or an inner washer or seal has failed. Most leaks start small, so the best thing to do is catch the drips, avoid forcing the valve and get it checked soon. Corrosion on older valves can also play a part.

Where a Stopcock Leak Usually Comes From

Your stopcock is the valve that controls the cold water coming into your home. It is often under the kitchen sink.

The most common leak point is around the spindle, just under the handle. Inside is a gland packing or seal that stops water escaping as the spindle turns. Over time this packing dries out or wears, and a slow weep may appear when the valve is moved.

Leaks can also come from the compression joints on each side of the valve. These joints can loosen with age, pipe movement or temperature changes. Inside the valve, a worn washer may mean it no longer shuts off fully, even when no water is dripping outside.

Older stopcocks can show green or white crusty deposits. This corrosion can be associated with slow leaks and may weaken the valve body over time.

Safe Steps to Take Straight Away

Put a towel around the valve and place a bowl or tray underneath to catch drips. Move anything that could be damaged. If water is near any sockets or electrics, keep clear and get an electrician to check them.

Try not to overtighten the gland nut or the joints. A small turn can sometimes help, but too much force can crack fittings or damage old pipework. Never use a long lever or hammer on a stiff handle.

If the stopcock itself is leaking badly and you cannot stop the water, the outside stop valve may be the next option. Thames Water says the outside stop valve should only be used in an emergency, and it is usually under a small cover on the path or pavement. If you cannot find it or it will not turn, call your water supplier or a plumber.

Signs the Leak Is Getting Worse

Keep an eye on the area for a day or two. Warning signs include drips that become a steady trickle, water pooling in the cupboard, or damp spreading into the floor or skirting board.

Other signs include a handle that has become very stiff or loose, or a valve that no longer shuts the water off properly. Any of these suggest the valve needs attention rather than more waiting.

When to Call a Plumber

A leaking stopcock is not something to ignore, because you rely on it in an emergency. A plumber can check whether the valve needs new packing, a tightened joint or a full replacement. Our page on stopcock repair and replacement in Swindon explains how this work is usually carried out.

If your stopcock has started to weep or drip, Emergency Plumber Swindon can take a look and talk you through the options. Give us a call on 01793 569521 and we will help you decide on the next step.
