Leaking Tap Repair in Preston - What One Homeowner Found Behind Their Kitchen Tap

Published August 2026 | Leaking Tap Repair Guide

A homeowner in Preston noticed their kitchen tap had developed a slow but persistent drip sometime in early spring - one of those rhythmic ticks you half-ignore for weeks until it starts keeping you awake at night. They'd tried cranking the handle tighter, which made no difference whatsoever, and had stuffed a cloth under the spout to muffle the sound. By the time they booked a plumber through the Voltrade platform, the drip had spread to the bathroom basin tap upstairs, and their water usage had climbed enough to show up on their quarterly bill. What looked like a minor nuisance turned out to be two separate faults requiring two different fixes - and the diagnosis told us a lot about how taps actually fail.

What Was Actually Going On

When our engineer arrived at the property in Preston and ran a proper assessment, the kitchen tap and the bathroom tap had two entirely different problems - which is more common than most people expect.

The kitchen tap was a traditional pillar tap, the kind with separate hot and cold controls that you find in a lot of older Lancashire homes. These taps use a rubber washer seated against a valve seat inside the tap body. Every time you turn the tap off, the washer is compressed against that seat to create a seal. Over time - typically several years of regular use - the rubber degrades, hardens, or gets scored by mineral deposits in the water supply. When that happens, the seal becomes imperfect, and water finds its way through even when the tap is fully closed. That's exactly what had happened here. The washer on the hot tap had flattened and cracked, and the valve seat underneath had developed a slight groove from years of contact.

The bathroom basin tap was a different animal entirely. It was a modern ceramic disc mixer tap - the type with a single lever that controls both temperature and flow. Instead of a rubber washer, these taps use two ceramic discs that rotate against each other. When aligned correctly, they block the water. When one disc chips, warps, or accumulates limescale build-up along its face, the seal breaks down. The homeowner's bathroom tap had a fractured ceramic cartridge, almost certainly caused by a water hammer event - a sharp pressure surge in the supply pipe that puts sudden mechanical stress on internal components. This can happen when a washing machine or dishwasher valve closes abruptly, or when there's work done on the local supply network.

We used the Voltrade GoFIX diagnostic process to log both faults clearly before we started work, which meant we could quote accurately for parts and confirm the scope of the job with the homeowner before touching anything. This kind of up-front clarity matters - especially when you're dealing with two separate tap types that need two different sets of replacement parts.

How the Problem Was Resolved

Fixing the kitchen tap required a washer and seat service. Here's the sequence our engineer followed:

1. Turn off the water supply to the tap - either at the service valve under the sink or at the rising main stopcock if there's no isolator fitted.
2. Open the tap fully to release any residual pressure in the line and drain standing water from the pipe.
3. Remove the tap handle - typically held by a small screw hidden under a decorative cap on top.
4. Use a tap spanner or adjustable spanner to unscrew the gland nut and withdraw the headgear assembly.
5. The old washer sits at the base of the headgear, held by a small nut. Remove it, fit the new washer, and tighten the nut - but not so hard that you deform the new rubber.
6. Inspect the valve seat inside the tap body. If it's grooved or pitted, it needs dressing with a tap reseating tool, which resurfaces the metal to give the new washer something flat to seal against. Skipping this step is the reason many DIY washer replacements fail within weeks.
7. Reassemble in reverse, turn the supply back on slowly, and check for leaks at the gland and around the spout.

The bathroom ceramic disc tap required a full cartridge replacement rather than a simple washer swap. Ceramic cartridges are not repairable - once a disc chips or cracks, the entire unit needs to come out. The process is similar in terms of isolating the supply and removing the handle, but the cartridge itself is a single cassette that lifts out once a retaining nut is removed. The replacement cartridge has to match the original precisely - brand, diameter, and spindle configuration all matter. Our engineer brought two sizes to the job based on the tap model identified beforehand, which avoided a wasted second visit.

Both repairs were completed in a single visit. The kitchen tap was done first, then the bathroom. Total active work time on site was around an hour and twenty minutes, plus time spent running the taps to confirm there were no remaining leaks before signing off the job.

What This Cost and How Long It Took

This is the question most Preston homeowners ask first, and it's fair enough. Here's an honest breakdown based on what this job actually involved.

A straightforward washer replacement on a single pillar tap - call-out, labour, and parts - typically costs between 80 and 130 pounds. If the valve seat needs regrinding, add another 20 to 40 pounds for the additional time and tool use. For this job, the kitchen tap repair came to around 110 pounds including the seat dressing work.

Ceramic cartridge replacement is generally a bit more, because the cartridge itself costs more than a rubber washer. Depending on the tap brand and cartridge specification, parts can range from 15 to 60 pounds. Labour-wise it's a similar time commitment to a washer job. Expect the total for a single ceramic disc tap repair to sit between 100 and 160 pounds in most cases.

For this homeowner in Preston, the combined bill for both taps - single call-out, all parts, all labour - came to 215 pounds. That's at the upper end of what you'd pay for two tap repairs, but the valve seat regrinding on the kitchen tap added time and there was a slightly awkward access situation under the bathroom basin that slowed things down.

The job was booked in the morning and completed the same afternoon. From the time the engineer arrived to the time they left was roughly two hours. There was no return visit required.

For context on the cost of doing nothing - a tap that drips once per second wastes approximately 12,000 litres of water per year. In a metered property in Lancashire, that translates to a meaningful addition to your water bill every quarter, and it compounds if multiple taps are dripping simultaneously.

How to Spot the Same Issue in Your Home

Leaking taps aren't always obvious. The drip under a tap cover or around the base can go unnoticed for months, and not all leaks present as a visible drip from the spout. Here are the signs to watch for:

Dripping from the spout when the tap is fully off

This is the classic symptom and the most common presentation our engineers see in Preston properties. If water is still coming out when the tap is fully closed, you almost certainly have a worn washer or a damaged cartridge. The rate of drip tends to worsen over time as the degraded component gets further damaged by continued use.

Water pooling around the base of the tap

If you notice water around the tap body rather than from the spout, the problem is usually with the O-rings or gland packing - the seals that prevent water from tracking up and out around the spindle. This is common in older taps and can make the area around the tap permanently damp, which eventually leads to damage to the worktop or basin surround if left long enough.

A stiff or grinding tap handle

Stiffness in a tap handle is often a sign that the ceramic discs are damaged or that limescale has built up inside the cartridge. In hard water areas of Lancashire, this can accelerate significantly. Don't force a stiff tap - grinding ceramic against ceramic speeds up the damage and can turn a cartridge replacement into a full tap replacement if the disc fragments lodge in the valve body.

Unexplained increases in your water bill

If you're on a water meter - which is increasingly common in newer Preston builds and in properties where meters have been installed on request - a sudden increase in your usage reading without a clear explanation is worth investigating. Check all taps, including outdoor taps and utility room connections, for slow drips you might have missed.

Condensation or damp patches under the sink

A slow weep from a supply fitting or compression joint under the sink can be hard to spot directly. If the inside of your under-sink cupboard smells musty or you notice damp on the base board, run your hand along the pipework and fittings to feel for moisture.

Lessons - What Every Preston Homeowner Should Know

After talking through the repairs with this homeowner in Preston, a few things came up that are worth passing on to anyone dealing with a leaking tap - or trying to avoid one.

Know what type of tap you have before anything else. The repair approach for a traditional pillar tap and a ceramic disc tap are completely different. Buying a bag of assorted washers from a hardware shop is the right move for one and useless for the other. Identifying your tap type - which you can usually do by looking at the handle movement (circular vs quarter-turn) and checking if the tap has separate hot and cold controls or a single mixer lever - saves wasted time and money on the wrong parts.

Isolator valves are worth their weight. A lot of older properties in Preston and across Lancashire don't have individual service valves (isolators) on each tap supply. That means turning off the tap requires shutting off the whole house water at the rising main, which is inconvenient and means no water anywhere in the property during the repair. If you don't have isolators fitted under your sink and basin, it's worth asking a plumber to add them when they're next on site - it's a small cost that makes every future repair faster and cheaper.

Hard water is working against your taps. Preston sits in an area with moderate water hardness compared to parts of the South East, but limescale still accumulates inside tap cartridges and on valve seats over time. Descaling spray used periodically around tap heads can help, and if you're in a particularly hard water area within Lancashire, a plumber can fit inline scale reducers to the supply feeding your taps.

A dripping tap is not a small problem. We hear this a lot - "it's just a drip." But beyond the water waste, a leaking tap is evidence that the internal components are worn. Those worn components don't get better on their own, and a tap that drips today will eventually either flood when the washer gives out completely, or start leaking at the gland and cause water damage to the surface it's mounted on. Dealing with it when it first starts dripping is always cheaper than waiting.

Tap replacement vs repair - know the crossover point. Washer and cartridge replacements make sense for taps that are otherwise in good condition. But if a tap is more than 15 to 20 years old, has corroded body work, or has already been repaired multiple times, replacement is often the more economic option. New taps for a kitchen or bathroom basin typically start around 40 to 80 pounds for a decent quality fitting, with installation on top. Our engineers in Preston regularly help homeowners weigh up whether a repair or a full swap makes more sense for their situation.

Related Questions

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

Only if you have a service valve (isolator) on the supply pipe below the tap - these are the slotted valves you turn 90 degrees with a flathead screwdriver. If you have one, you can isolate just that tap without cutting off water to the whole house. If you don't have an isolator, you'll need to shut off at the rising main stopcock first. Attempting to remove a tap headgear without isolating the supply first will result in a significant amount of water coming out very quickly.

How long does a tap washer replacement typically last?

A good quality rubber washer, properly fitted against a sound valve seat, will commonly last five to ten years under normal use. Cheaper washers, or replacements fitted without regrinding a worn valve seat, can fail within months. Ceramic cartridges generally last longer than rubber washers - often ten years or more - but are more susceptible to damage from pressure spikes and hard water scale build-up. Buying decent quality replacement parts rather than the cheapest available makes a real difference to longevity.

Why does my tap drip only after I've used it, not constantly?

This is a common pattern with ceramic disc taps, and it usually points to a partially failing cartridge. When the tap is cold, the discs contract slightly and create just enough seal to prevent dripping. Once the tap has been used and the body warms up from hot water passing through, thermal expansion causes the damaged disc to leak. It can also happen in reverse - some taps drip only in cold weather when the metal contracts. Either way, intermittent dripping after use is a reliable sign that a cartridge service or replacement is due.

Is a leaking tap covered by home insurance?

In most cases, no. Standard home insurance policies in the UK typically cover sudden and unforeseen water damage - for example, a burst pipe - but exclude gradual damage caused by a known leak or ongoing wear. A dripping tap that's been left to deteriorate over time is unlikely to be covered, and any damage to cabinetry or flooring that results from a slow leak you were aware of may also be excluded. Check your policy wording carefully, and if in doubt, contact your insurer before making a claim. Getting the tap fixed promptly is the safer approach both financially and practically.
