Leaking Tap Repair Guide for Taunton Homeowners

Published September 2026 | Leaking Tap Repair

How Long Should a Tap Last and What Affects That

A tap's lifespan is not really about the tap body itself - that chrome or brass shell could sit on your sink for decades without issue. What wears out are the working parts inside: the washer that presses against the valve seat to stop water flow, the O-rings that prevent leaks around the spindle, and in modern mixer taps, the ceramic disc cartridge that controls both temperature and flow in a single turn.

In most cases, a traditional pillar tap fitted with rubber washers will need its first washer replacement somewhere between 5 and 10 years of regular use. Ceramic disc cartridges in quality mixer taps commonly last 10 to 20 years before they start to leak or stiffen. Budget taps with inferior internal components can start causing problems in under 3 years.

What accelerates wear more than anything else in Taunton and across Somerset is water hardness. Parts of Somerset draw from groundwater sources that carry higher mineral content, and that calcium and magnesium deposits itself on valve seats, cartridges, and aerators over time. Every time a hardness-scaled seat is closed against a washer, you're pressing rubber onto a rough, uneven surface. That friction shortens washer life considerably compared with what you'd see in a soft-water area.

Usage patterns matter too. A bathroom tap used twice a day for teeth brushing will outlast a kitchen tap turned on and off dozens of times daily. Over-tightening - that instinct to give the tap one final hard turn to make sure it's off - is one of the most common causes of premature washer failure our engineers see. It crushes the washer rather than seating it properly, creating the very drip it was meant to prevent.

The Maintenance That Actually Makes a Difference

Most people do nothing to their taps until a drip appears. That's understandable - they're not the most exciting part of a house. But a small amount of attention every year or two can genuinely push a tap's useful life out by 10 years or more, and prevent the kind of damage that a persistent leak causes to the surrounding woodwork, silicone seals, and cabinet interiors.

The most effective maintenance steps are:

1. Descale the aerator every 6 to 12 months. The aerator is the small mesh insert at the tip of the spout. It collects limescale and debris faster than anywhere else on the tap. Unscrew it by hand or with pliers wrapped in tape, soak it overnight in a cup of white vinegar, then rinse and refit. This takes 2 minutes and costs nothing. It also improves flow rate noticeably if scale has built up.
2. Check the tap base for dampness once a year. Run your finger around the base where the tap meets the sink surface. Any moisture there suggests the O-ring around the body is starting to go. Catching this early means a simple O-ring replacement rather than water damage to the cabinet below.
3. Don't ignore stiffness. A tap that's becoming hard to turn isn't just an annoyance - it's telling you the cartridge or spindle packing is wearing. Having it looked at before it fails means a controlled repair rather than an emergency job when the internals seize or crack.
4. Lubricate moving parts during any repair visit. When a plumber is already inside the tap to replace a washer, they should be applying food-safe silicone grease to the spindle and O-rings as part of the job. If this step is skipped, the repaired tap will wear faster than it should.
5. Use a water softener if hardness is a persistent problem. For households in harder water pockets of Somerset, fitting a point-of-use or whole-house softener can significantly extend the life of tap cartridges and valve seats. It's a larger upfront cost but it protects every water-using appliance in the property.

Warning Signs a Tap Is Reaching End of Life

A dripping tap is the obvious signal, but it's rarely the first one. By the time water is visibly falling from the spout between uses, the internal components have usually been struggling for some time. Learning to read the earlier signs means you can intervene cheaply rather than urgently.

Dripping when turned off. Even a slow drip wastes a surprising volume of water over a year and points clearly to a failed washer or worn ceramic disc. This is typically the most repairable of all tap faults and the one our engineers in Taunton deal with most frequently.

Leaking around the base of the spout. This indicates O-ring failure around the body of the tap. In mixer taps especially, a weeping base is a sign the seals around the cartridge housing have degraded. Left alone, this water tracks down into the cabinet and causes timber swelling, mould, and eventually silicone seal failure where the tap meets the sink.

Visible corrosion or pitting on the tap body. Chrome plating that's blistering or pitting isn't just cosmetic - it often indicates that moisture has worked its way behind the surface, which can point to underlying seal failure. Brass bodies under failing chrome will continue to function, but the structural integrity of the tap should be assessed.

Handle that rocks or moves when operated. A loose handle on a traditional tap suggests the gland packing has worn to the point where the spindle is no longer held firmly. On a mixer tap, handle movement can mean the cartridge retaining clip has failed. Either way, continued use risks snapping internal components.

Reduced or uneven flow that doesn't clear after descaling the aerator. If cleaning the aerator doesn't restore normal flow, the issue is likely internal scale on the cartridge itself or partial blockage in the supply isolation valve below the sink. This is worth investigating rather than leaving, as it can worsen and affect other outlets on the same circuit.

Repair vs Replace - The Honest Calculation

This is the question homeowners in Taunton ask us most when we arrive to look at a leaking tap. The answer depends on a few practical factors, and it's worth thinking through them clearly rather than defaulting to one answer or the other.

When repair makes sense: If the tap body is in good condition, the leak is caused by a washer or cartridge failure, and the tap is a quality fitting from a reputable manufacturer, repair is almost always the right call. A washer replacement typically costs between 60 and 120 pounds including a plumber's call-out in most Somerset towns. A cartridge replacement in a quality mixer tap commonly runs between 90 and 180 pounds depending on the cartridge specification. Both repairs will extend the tap's life by several years.

When replacement makes more sense: If the tap is more than 20 years old, if the valve seat inside has become pitted and corroded (a new washer won't seal properly against an uneven seat), or if the body itself is cracked or showing significant corrosion, replacement is typically better value. Fitting a new tap in Taunton generally costs between 150 and 350 pounds for a standard installation - more for specialist fittings or if pipework access is complicated. Paying for two or three rounds of repair on an old tap with multiple problems often ends up costing more than a single replacement would.

The seat-regrinding option. There's a middle path that's often overlooked: valve seat regrinding. A plumber can use a seat grinder tool to resurface a pitted or corroded seat without replacing the whole tap. This extends tap life significantly when the body is otherwise sound and the problem is specifically the seat. Not all plumbers carry the tool, so it's worth asking when you get a quote.

Our engineers use the Voltrade GoFIX diagnostic approach to assess taps at the start of every job - checking supply pressure, valve seat condition, cartridge wear, and body integrity before recommending repair or replacement. This takes a few minutes but means the recommendation you get is based on actual condition rather than guesswork.

Annual Service - What It Should Include

Most homeowners don't service their taps annually - that's honest. But for properties where taps are used heavily, where water hardness is a factor, or where the plumbing is older, an annual check alongside a boiler service or general plumbing inspection makes good practical sense.

A proper tap inspection should cover:

1. Flow rate check on each outlet. Comparing flow rates across taps in the property quickly identifies partial blockages or pressure drops on specific circuits.
2. Aerator removal and inspection. Scale buildup is measured visually. Heavy scale after 6 months indicates the property would benefit from a water softener or more frequent cleaning.
3. Spindle or cartridge condition check. A plumber can assess cartridge wear by feeling resistance and smoothness through operation. Cartridges that are starting to feel gritty or sticky are approaching the end of their life.
4. O-ring and gland packing inspection. Any sign of moisture around tap bases, handles, or supply connections is noted and addressed.
5. Isolation valve check. The isolation valves under sinks and beside baths are often seized or stiff because they're never operated. A service visit should include testing that each isolation valve actually works - a seized valve on a leaking tap turns a 10-minute job into a mains shutoff situation.
6. Silicone seal inspection. Where taps are deck-mounted or fitted to ceramic sinks, the silicone seal around the base should be checked for cracking or mould. Failed silicone is a common route for water to reach timber under a sink.

Simple Habits That Extend the Life by Years

Beyond formal maintenance, there are everyday habits that have a real cumulative effect on how long your taps last. None of these require any technical knowledge - they're just adjustments to how you use taps day to day.

Turn taps off firmly but not hard. The tap should stop dripping when it feels closed - that's enough. Forcing it further past that point is what crushes washers and scores valve seats. If you need to apply real force to stop a drip, that's a sign the washer needs replacing, not a sign to push harder.

Don't hang weight from taps or spouts. A common cause of spout seal failure in kitchen sinks is using the tap as a support - hanging cleaning cloths over it, resting heavy pots against it while they drain. The forces this creates on the base seals over time are more significant than they look.

Run the cold tap fully before drawing water from a tap that's been unused for a few weeks. Stagnant water in tap bodies can deposit sediment on cartridges and aerators. Flushing for 30 seconds clears this before it has a chance to bed in.

Address hard water deposits before they build up significantly. A light monthly wipe of tap surfaces with diluted white vinegar or a proprietary limescale remover prevents scale from bonding to chrome and working its way into joints and aerator threads. Once scale is thick and hardened it requires more aggressive treatment that risks surface damage.

Know where your isolation valves are. This isn't maintenance exactly, but it means that when a tap starts leaking badly you can isolate it immediately rather than running around looking for the stopcock while water is dripping. Many Taunton properties we visit have isolation valves that homeowners didn't know existed, often under bathroom basins or behind bath panels.

Maintenance Questions

How much does it typically cost to fix a dripping tap in Taunton?

A standard dripping tap repair in Taunton - replacing a worn washer on a traditional pillar tap - typically costs between 60 and 120 pounds including the plumber's call-out and parts. Cartridge replacement in a mixer tap commonly runs between 90 and 180 pounds depending on the cartridge itself, which can range from 10 to 80 pounds for the part alone. Specialist taps from premium brands may require specific cartridges that push the parts cost higher. Always ask for a fixed price before work starts rather than an hourly rate for this type of job.

Can I replace a tap washer myself without turning off the mains?

In most cases, yes - if you have working isolation valves under the sink or basin. Turn the isolation valve clockwise until it stops (usually a quarter turn on a slotted valve), then turn the tap on to release any remaining pressure in the pipe before opening the tap body. If there are no isolation valves, you'll need to turn off the mains stopcock. The job itself isn't technically difficult, but if you're not confident working with plumbing, or if the tap body is stiff or corroded, it's worth getting a plumber in to avoid the risk of making the situation worse.

Why does my tap drip only after it's been used, then stop?

This is commonly caused by thermal expansion. When hot water passes through a tap, the metal components expand slightly. If the washer or cartridge is already worn, this expansion can temporarily break the seal, causing a drip that stops once everything cools and contracts. It's a sign the internal sealing component is near the end of its life rather than completely failed. You'll typically get a short window before it becomes a constant drip, so it's worth having it looked at soon rather than waiting until it worsens.

How do I know if my tap problem is the cartridge or the washer?

Traditional taps with separate hot and cold handles almost always use rubber washers - these are the pillar taps common in older Somerset properties and many bathrooms across Taunton. Single-lever or quarter-turn mixer taps use ceramic disc cartridges. If you have a mixer tap that drips from the spout when off, the cartridge is the likely culprit. If water leaks from around the handle rather than the spout, it's usually the O-ring around the cartridge housing. A plumber can confirm this in a few minutes by removing the handle and inspecting the internal mechanism directly.
