How to Fix a Dripping Tap Properly

That steady drip in the kitchen or bathroom is easy to ignore for a day or two. Leave it longer, though, and it starts costing you money, wasting water and becoming a sign that a small plumbing fault is turning into a bigger nuisance. If you are wondering how to fix a dripping tap, the good news is that some cases are straightforward. The less good news is that not every tap is built the same, and forcing the wrong repair can make the problem worse.

A dripping tap usually comes down to wear inside the fitting. In many homes, the issue is a washer, ceramic cartridge, valve seat or O-ring that has reached the end of its life. Over time, parts loosen, seals harden and limescale builds up. The result is a tap that no longer shuts off cleanly.

How to fix a dripping tap without causing more trouble

Before reaching for a spanner, it helps to work out what type of tap you have. Traditional pillar taps with separate hot and cold handles often use washers. Many modern mixer taps use ceramic cartridges. The repair method depends on that internal mechanism, so guessing can waste time and lead to the wrong replacement part.

Start by turning off the water supply. Some taps have isolation valves under the basin or sink, while others may require you to turn off the mains. Once the water is off, open the tap to release any pressure and plug the sink so that no small screws or fittings disappear down the waste.

Next, remove the tap handle. In some cases, there is a visible screw cap you can prise off carefully with a flat screwdriver. In others, the fixing screw is hidden beneath a decorative cover. Once the handle is off, you can get to the internal valve or cartridge.

If your tap uses a washer, the washer may be split, flattened or hardened. Replacing it with the same size can often solve the drip. If your tap uses a ceramic cartridge, the cartridge usually needs replacing as a complete unit. These need to match the make and model closely, which is where many DIY repairs slow down.

After fitting the new part, reassemble the tap carefully, turn the water back on and test it. If the dripping stops and the handle turns smoothly, you have likely sorted the problem. If it still drips, the fault may be deeper inside the tap body or linked to water pressure, limescale damage or wear that is not worth patching up.

The most common reasons a tap keeps dripping

In practical terms, most dripping taps come back to age, wear and water quality. Rubber washers and seals wear down through normal use. Ceramic cartridges can crack or collect debris. Internal metal parts can corrode. In hard water areas, limescale often shortens the life of tap components and stops them sealing properly.

There is also the issue of overtightening. Many people try to stop a drip by turning the tap handle harder and harder. That can damage the washer or strain the mechanism, especially on older taps. A firm close is enough. If it keeps dripping, the tap needs attention rather than more force.

Sometimes the drip is not really a tap fault at all. If a mixer tap drips from the spout after use for a short time, that can simply be leftover water draining through. A constant drip, however, is different. If it carries on long after the tap has been used, there is usually a worn component inside.

Washer taps and ceramic disc taps are not the same job

This is where a lot of homeowners get caught out. Older compression taps with washers tend to be more forgiving and often cheaper to repair. Modern quarter-turn taps with ceramic discs can be reliable for years, but when they fail, the replacement part needs to be correct. A cartridge that looks similar may still not seat properly.

That matters because a tap that is rebuilt with the wrong part might stop dripping for a day, then start again. In some cases it can also become stiff to turn, leak around the base or fail altogether.

Tools you may need before you start

You do not need a van full of kit to attempt a basic repair, but you do need the right basics. A flat screwdriver, crosshead screwdriver, adjustable spanner, cloth, replacement washer or cartridge and a little patience usually cover it. A cloth around chrome fittings can help prevent scratches when loosening parts.

What you should not do is attack the tap with too much force. Stuck covers and seized nuts are common, especially on older fittings. If something is not shifting easily, there is a point where persistence turns into damage. Cracked tap bodies and marked finishes are a common result of rushed DIY work.

When it is better to replace the tap

Sometimes repairing a tap is sensible. Sometimes it is simply throwing time at a fitting that is already on its way out. If the tap is old, heavily scaled, loose on the basin, leaking from more than one point or has had repeated repairs already, replacement is often the better option.

There is a cost trade-off here. A small internal part is cheaper than a full new tap, but only if the repair lasts. If the tap body itself is worn or parts are hard to source, fitting a new tap can be more practical and better value over time.

This is especially true in rental properties or busy family homes where reliability matters more than squeezing a bit more life out of a failing fitting. A proper repair or replacement saves the hassle of repeated call-outs and ongoing water waste.

How to fix a dripping tap if the leak is not from the spout

Not every tap leak is a classic drip from the outlet. Water around the base of the tap, around the handle or beneath the sink points to a different issue. That could be an O-ring, a loose connection, worn flexible tails or a fault in the body of the tap itself.

These jobs can be more awkward than they first appear, especially under kitchen sinks where access is tight. What seems like a quick fix from above often turns into a longer job once you are working in a cramped cupboard with limited room for tools.

If water is appearing under the sink, it is worth dealing with quickly. Even a slow leak can damage units, flooring and surrounding surfaces over time.

Signs you should call a plumber

There is nothing wrong with trying a simple tap repair if you are confident and have correctly identified the problem. But there are clear cases where professional help is the safer option.

If you cannot isolate the water supply, if the tap is seized, if the fittings are heavily corroded, or if you are not sure what replacement part you need, calling a plumber usually saves time. The same goes for taps that keep dripping after a repair attempt. At that stage, the issue is often more than just a worn washer.

For homeowners, tenants and landlords in Exeter, fast help matters when a plumbing problem is affecting daily use of the kitchen or bathroom. A local plumber can identify whether the right fix is a part replacement, a full tap change or attention to a related plumbing issue.

A quick repair is only useful if it lasts

The main thing people want is simple - stop the drip and keep it stopped. That is why the quality of the repair matters more than whether it was done in ten minutes. A temporary fix that fails next week is not much of a saving.

At Plumbers Exeter, we see plenty of small tap issues that started as minor annoyances and became repeated problems because the first repair was rushed or the wrong part was fitted. Getting it sorted properly the first time is usually the better route.

A few simple ways to prevent future drips

You cannot stop every tap from wearing out eventually, but a few habits help. Avoid overtightening handles. Deal with small stiffness or minor leaks early rather than waiting. If you live in a hard water area, be aware that limescale shortens the life of tap parts and fittings.

It is also worth paying attention to changes in how a tap feels. If it starts turning roughly, loosening at the base or dripping intermittently, that is usually the early warning stage. Small faults are generally easier and cheaper to deal with before they turn into full failures.

A dripping tap is one of those household problems that seems minor until it starts getting on your nerves, pushing up water use or causing wear elsewhere. Some repairs are simple enough. Others need the right parts, the right access and a bit of experience. If you are not sure which sort of job you are dealing with, getting it looked at early is often the easiest way to put the problem to bed.
