Leaking Tap Repair in Nantwich - A Real-World Guide for Cheshire Homeowners

Published August 2026 | Leaking Tap Repair

A homeowner in Nantwich noticed the drip from their bathroom basin tap had shifted from occasional to constant over the space of a few weeks. At first it was easy to dismiss - a tap that drips once every thirty seconds doesn't feel like an emergency. But then the water bill arrived, and there was a rust-coloured ring forming in the ceramic basin that scrubbing wouldn't shift. By the time our engineer arrived, the tap was losing around half a litre of water every hour, and the homeowner had already tried the classic move of tightening the handle as far as it would go - which had made no difference at all, and had very likely made the underlying problem worse.

What Was Actually Going On

The first thing our engineer did was identify the tap type. This matters more than most people realise, because different tap mechanisms fail in different ways and need different fixes - and treating the wrong cause wastes time and money.

There are two main types of tap you'll find in most Nantwich homes. Compression taps are the traditional style. They use a rubber washer on the end of a metal spindle, which is pressed down against a valve seat to stop the water flow. When the washer wears out or the seat becomes pitted, the tap drips. These are common in homes built before the mid-1990s and are still fitted in a significant number of new builds and refurbishments today. Ceramic disc taps are the other type, and they work completely differently. Two precision-machined ceramic discs sit inside a plastic cartridge. When you turn the handle, one disc rotates relative to the other, aligning holes to allow water through or closing them off to stop it. Quarter-turn handles are the giveaway - that smooth, satisfying half-rotation from fully off to fully open is ceramic disc territory.

The tap in this Nantwich home was a ceramic disc model - a mid-market fitting installed around 2015. Our engineer shut off the water at the under-sink isolator valve (a small slot-head screw on the supply pipe - a quarter turn closes it) and removed the tap handle by popping off the decorative cap on top and unscrewing the handle screw beneath. With the handle off, the cartridge - the whole ceramic disc assembly in its plastic housing - came out as a single unit.

What they found was a ceramic disc with a hairline fracture, almost certainly caused by a combination of thermal stress and limescale accumulation. Cheshire has moderately hard water, and in Nantwich specifically, water hardness typically runs between 200 and 250 parts per million of calcium carbonate. That's enough to deposit significant limescale inside a tap cartridge over several years of use. The scale had built up around the disc until, at some point, the pressure caused it to crack. Once cracked, even microscopic movement allows water to bypass the seal - hence the drip that tightening the handle could never cure. There was also scoring on the O-rings around the cartridge body, which explained the slight dampness at the base of the handle the homeowner had noticed but hadn't connected to the main problem.

How the Problem Was Resolved

Fixing a ceramic disc tap comes down to replacing the cartridge - and inspecting the O-rings while everything is open. Here's how the repair unfolded, step by step.

1. Water off at the isolator. The isolator valve under the sink was turned off first. If there's no isolator, the repair requires shutting off the main stopcock - typically found under the kitchen sink, in an airing cupboard, or beneath the stairs. Every homeowner in Nantwich should know where theirs is before they need it.
2. Handle removal. The decorative cap on top of the tap handle - usually a snap-fit or secured with a small Phillips screw - came off first, revealing a cross-head screw beneath. Remove that, and the handle lifts straight off.
3. Shroud removal. The chrome collar beneath the handle unscrews anticlockwise. On older or limescale-affected taps these can be stubbornly tight. A rubber strap wrench does the job without scratching the chrome finish.
4. Cartridge extraction. The cartridge sits behind a hexagonal retaining nut that takes a spanner. Once that's undone, the cartridge pulls straight out. If it's stuck with limescale, a short soak with descaler can loosen it without forcing.
5. Like-for-like replacement. This is where experience earns its money. Tap cartridges are not universal. They vary by brand, body diameter, spindle height, and flow direction. Our engineer matched the cartridge to the tap's manufacturer specification - a compatible ceramic disc unit sourced the same day. Common brands like Bristan, Grohe, Ideal Standard, and Pegler all use cartridges that are widely available, but getting the wrong one means the repair fails immediately.
6. O-ring replacement. With the cartridge out, the O-rings on the tap body were replaced. These cost pennies each and it makes no sense to reassemble without changing them if they're showing any wear at all.
7. Reassembly and testing. Everything went back in reverse order. The isolator was opened slowly, the tap tested through its full range of movement, and our engineer checked underneath the sink with a dry cloth to confirm no weeping connections.

Total time on site: just over an hour, including time spent matching the cartridge and pulling O-rings from van stock.

What This Cost and How Long It Took

Leaking tap repairs in the Nantwich area tend to fall into a fairly predictable price range, though the final figure depends on the tap type, whether parts need sourcing, and what state the pipework is in.

For a ceramic disc cartridge replacement on a single tap, expect to pay in the region of £80 to £150 all in. That typically covers an hour of labour plus the cartridge itself. Cartridges for common tap brands cost between £15 and £45 depending on the specification and whether they're a direct manufacturer part or a quality compatible unit.

A rubber washer replacement on an older compression tap is cheaper - sometimes as little as £50 to £80 for a callout, since the washer itself costs very little and the job takes 20 to 30 minutes once the water is isolated. If the tap also needs a new O-ring set or gland packing, add a small amount for parts, but the labour cost stays similar.

Where costs climb is when the valve seat is damaged. The valve seat is the internal brass or stainless fitting that the washer or disc presses against to seal. Years of over-tightening a dripping tap can pit or score this surface, so even a new washer can't form a proper seal against it. A plumber can re-cut the seat with a seat grinder for an additional £20 to £40, but on very old taps where the seat is badly corroded or spare parts are no longer available, a full tap replacement becomes the better call.

A new tap, supplied and fitted, typically costs £150 to £350 - covering the tap itself plus labour. Budget toward the upper end for quality brands, for monobloc mixer taps with more complex connections, or where access to the supply pipework is awkward.

The repair in this Nantwich home came to £125 all in. The homeowner had been watching the drip for around six weeks before calling. At half a litre per hour, that's roughly 500 litres of water wasted - and with metered water in Cheshire typically charged at around 150 pence per cubic metre including sewerage, the financial cost of the delay was modest. But the basin staining needed professional cleaning to remove, and water damage to vanity units and chipboard shelving compounds silently over time. Acting earlier is nearly always the cheaper outcome.

How to Spot the Same Issue in Your Home

Most leaking taps give you clear warning signals well before the drip becomes serious. Knowing what to look for means you can catch a problem while the fix is still simple.

Dripping from the spout when the tap is fully off is the classic sign of a worn internal component - either a rubber washer in a compression tap, or a cracked or degraded ceramic disc in a quarter-turn tap. The faster the drip, the more degraded the component. A tap that was dripping once every minute last week and is now dripping twice every minute is telling you something is actively getting worse.

Water around the base of the handle or collar points to an O-ring or gland seal failure. This is a separate issue from a spout drip - you can have one without the other, or both at the same time. Left long enough, this type of leak tracks down into the vanity unit and onto the chipboard shelf beneath the sink, which rots quietly and invisibly.

A tap that's become stiff or resistant to turn is often limescale building up inside the cartridge. This is particularly common in Nantwich and across the wider Cheshire region given the moderately hard water supply. Forcing a stiff ceramic disc tap increases the risk of cracking the disc - so if your tap is noticeably harder to turn than it used to be, that's the time to have it looked at, not after it starts dripping.

Staining in the basin below the spout - rust-coloured rings, white mineral deposits, or brown streaks - is a reliable indicator that a drip has been running long enough to leave a trace. It won't tell you how serious the leak is, but it tells you the problem predates today.

An unexplained rise in your water meter reading can point to a tap you've simply stopped noticing. Many slow drips become familiar enough that they disappear into background noise. If you're on a meter, check it last thing at night and again first thing in the morning with no water used overnight - any movement is a leak somewhere in the system.

What Every Nantwich Homeowner Should Know

These are the things that come up again and again when our engineers deal with leaking taps across Nantwich and the surrounding area. None of them are complicated, but they can save you real money.

Never keep forcing a dripping tap tighter. It's instinct - the tap drips, you tighten it harder. But on both compression and ceramic disc taps, this accelerates wear on the internal components and can scar or pit the valve seat. A damaged valve seat means a new washer or cartridge won't fully seal against it, turning a £80 repair into a more involved job. If tightening the tap hasn't stopped the drip, stop tightening it.

Limescale is the slow killer of tap components in this area. With water hardness running as it does across Nantwich, ceramic cartridges that might last 15 years in a soft-water area are sometimes failing in 8 to 10 years. Running a proprietary descaling solution through your taps periodically - or fitting a simple inline scale inhibitor on the supply pipes - can meaningfully extend the life of your cartridges and keep them turning smoothly.

Know where your stopcock is, and make sure it turns. In an emergency - a pipe bursting, a flexi-hose failing, a tap fitting that won't go back together - being able to kill the water supply instantly is critical. Stopcocks that haven't been operated in years can seize solid. Turn yours a quarter turn closed and then back open once a year just to keep it free. If it won't move at all, that's a job for a plumber before you're in a crisis.

Monobloc mixer taps and bath shower mixers use different cartridges. A single-lever monobloc tap over the kitchen sink or bathroom basin uses a cartridge that controls both temperature and flow in one unit - these are more expensive to replace than a standard hot or cold cartridge, typically £25 to £60 for the part alone. They're not more difficult to diagnose, but budget accordingly. Thermostatic shower bar valves and concealed shower valves have their own cartridge types and can be even more specific to source.

Not every apparent tap leak is the tap itself. Occasionally what presents as a tap problem is actually a weeping joint on the supply pipe inside the vanity unit, a corroded flexi-hose connection, or a loose compression fitting. Always check under the sink or inside the unit before assuming the tap mechanism is at fault. A quick look with a torch can save a wasted callout charge.

Related Questions

How long does a leaking tap repair usually take?

For most tap repairs - a washer replacement on a compression tap or a cartridge swap on a ceramic disc model - allow between 30 minutes and 90 minutes on site. The main variables are access to the tap, whether the correct replacement cartridge is immediately available on the engineer's van, and whether any secondary issues such as a seized isolator valve or a pitted valve seat need addressing at the same time. If you're booking without having confirmed the tap type in advance, allow up to two hours to be safe.

Can I fix a dripping tap myself?

You can, and a rubber washer replacement on an older compression tap is one of the more accessible plumbing jobs for a confident DIYer - the parts cost pennies and the process is logical. Ceramic disc cartridge replacements are also achievable if you can correctly identify and source the matching cartridge. The most common pitfall is getting the cartridge wrong, or cracking a shroud or fitting when removing a limescale-seized collar. If you're uncertain about any step, a professional repair is typically less expensive than the result of getting it wrong and creating a secondary problem.

How much does a leaking tap repair cost in Nantwich?

In the Nantwich area, most leaking tap repairs - covering labour and parts - fall between £80 and £150. A simple washer replacement on an older tap usually sits at the lower end of that range. A ceramic disc cartridge replacement, particularly on a mixer tap with O-ring work included, tends to come in at the middle to upper end. If the tap itself needs replacing rather than repairing, budget £150 to £350 depending on the tap specification, brand, and complexity of the existing pipework connections.

Why is my tap still dripping after I replaced the washer?

The most likely cause is a damaged valve seat - the brass or stainless ring inside the tap body that the washer presses against to form a seal. If that surface is scored or pitted (commonly from years of over-tightening the tap), a new washer simply can't create a watertight contact against it. A plumber can assess the seat and either re-cut it with a seat grinder or advise on whether the tap body itself is beyond economic repair. This is one of the more common reasons a DIY washer swap doesn't solve the drip.
