Leaking Tap Repair in Portsmouth - Your Complete Guide to Fixing Drips and Making Taps Last

Published August 2026 | Leaking Tap Repair Guide

How Long Should a Tap Last and What Actually Affects That

Taps are one of those household fixtures most people only think about when something goes wrong. But understanding what determines their lifespan can save you from unnecessary call-outs and help you catch problems before a small drip turns into a damaged cabinet or a swollen floor.

In general terms, a well-made tap fitted correctly should give you somewhere between 15 and 20 years of reliable use. Some budget taps from DIY sheds, particularly those at the cheaper end, might start failing within five or six years. On the other end, premium brands like Grohe, Hansgrohe, or Franke - fitted properly and maintained - can last well beyond two decades.

What actually shortens that lifespan? A few factors matter more than most people realise:

Water hardness. Portsmouth and the wider Hampshire area draw their water supply largely from chalk and limestone aquifers, which means the water here is notably hard. Limescale builds up inside tap bodies, on washers, and around ceramic discs, accelerating wear considerably. It's one reason our engineers see more tap failures in this part of the country compared to softer water areas further north.

Tap type. Traditional pillar taps with rubber washers are the simplest design - when they leak, you replace the washer, usually for a pound or two. Ceramic disc taps are smoother to operate and more water-efficient, but when the discs crack (often due to debris or overtightening), the repair is more involved. Monobloc mixer taps, common in modern kitchens, have more internal components and can develop drips from the spout, from the base, or from the hose connections underneath - each requiring a different fix.

Installer quality. A tap overtightened on installation will have its washer compressed from day one. One fitted without PTFE tape on the threads may weep from the base within months. Getting the initial fitting right matters more than most homeowners realise.

Usage frequency. A kitchen tap that gets used 30 or 40 times a day will naturally wear faster than a bathroom tap turned twice a day. Factor that in when budgeting for replacements.

The Maintenance That Actually Makes a Difference

Most tap maintenance takes ten minutes a month and requires nothing more than a cloth and some basic household products. The habits that keep taps running well are simple - it's the neglect that costs money.

Descaling the aerator. The aerator is the small mesh fitting screwed onto the end of the spout. In hard water areas like Portsmouth, limescale accumulates here faster than anywhere else. A clogged aerator reduces flow, forces you to turn the tap harder to get the pressure you want, and puts unnecessary stress on the internals. Unscrew it monthly, soak it in white vinegar for 20 minutes, rinse it, and screw it back. That's it.

Cleaning around the base. Water that pools around the base of a mixer tap doesn't just look unpleasant - it accelerates corrosion and can work its way into the cabinet below. Wipe the base dry after cleaning and check periodically that the O-rings sealing the tap body are still doing their job. A weeping base is often the first sign they're not.

Checking under the sink. Most homeowners never look under the sink unless something is already noticeably wrong. Get in the habit of opening the cabinet door every couple of months and having a look. Run both taps, check the flexi-hoses for any damp patches, look at the isolation valves, and feel along the pipe connections. Catching a slow weep early is the difference between a 15-minute job and a flooring repair bill.

Not overtightening. One of the most common causes of damaged washers is over-tightening the tap when shutting it off. You don't need to crank it hard - once the flow stops, that's enough. It's worth teaching everyone in the household the same habit, particularly children who often grip taps harder than necessary.

Using isolation valves correctly. Every tap should have isolation valves on the supply pipes underneath. If yours don't have them, it's worth getting them fitted - they let you isolate and repair a tap without turning off water to the whole house. Test that yours turn freely every six months. Valves left untouched for years can seize, which means a simple washer change turns into a much bigger job when you can't isolate the supply.

Warning Signs a Tap Is Reaching the End of Its Life

Most tap failures don't happen overnight. There's usually a sequence of warning signs that, if you know what to look for, give you plenty of time to act before the situation becomes urgent.

A persistent drip that comes back. If you've had a washer replaced and the drip returns within a few months, it's a sign the tap seat - the surface the washer presses against to form a seal - is damaged or corroded. At that point, the decision isn't whether to repair it again. It's whether the tap body itself is worth saving.

Stiffness or grinding. A tap that was once smooth but now requires real effort to turn is telling you the internals are worn. Ceramic discs can crack or become contaminated with debris. On older taps, the spindle thread can wear, making operation rough and inconsistent.

Corrosion on external surfaces. Surface pitting or discolouration on chrome fittings isn't just cosmetic. It often indicates that the chrome plating has broken down, which means the underlying brass or zinc alloy is exposed and actively corroding. Once corrosion gets inside the body, the tap's days are numbered.

Leaking from multiple points simultaneously. A tap that's dripping from the spout and weeping from the base at the same time is not a candidate for a simple repair. When a tap develops problems in several places at once, it usually means the materials throughout have aged to the point where fixing one thing will just reveal the next.

Unusual noise. Water hammer, whistling, or a groaning sound when the tap is turned can indicate worn internal components or wider pressure fluctuations in your system. Our engineers use the Voltrade GoFIX diagnostic process to trace whether unusual tap behaviour is caused by the tap itself or by something further back in the plumbing - because sometimes a failing pressure-reducing valve is making otherwise sound taps behave badly.

Repair vs Replace - The Honest Calculation

This is the question our engineers get asked most often, and the answer is rarely black and white. Here's how to think about it clearly.

A basic washer replacement on a traditional tap typically costs between 60 and 100 pounds in labour, depending on access and your location across the Portsmouth area. The washer itself costs pence. If your tap is otherwise in good condition and under ten years old, that's money well spent.

Replacing ceramic cartridges in a modern mixer tap typically costs between 80 and 140 pounds including parts, since quality cartridges from brands like Grohe or Hansgrohe are not cheap. Again, if the tap body is in good shape, this is worthwhile.

A new tap supply and fit - mid-range quality, professionally installed - will typically cost between 150 and 280 pounds for a kitchen mixer, or between 100 and 200 pounds for a bathroom basin tap. The range depends on tap quality, access difficulty, and whether the valves and connections underneath need updating at the same time.

The case for replacement rather than repair is stronger when:

1. The tap is more than 15 years old and has already been repaired once before.
2. The tap seat is damaged and would need regrinding - a job that adds labour cost and doesn't always produce a lasting result.
3. Replacement parts are no longer readily available, which is common with budget taps and discontinued ranges.
4. The tap body shows corrosion or cracking, particularly around the spout or base.
5. You're already planning a bathroom or kitchen renovation within the next two or three years.

The case for repair is stronger when the tap is a quality fitting in otherwise good condition, or when it's part of a matched suite that would be difficult or expensive to replace like-for-like. A plumber can give you a clear view of which way the numbers fall after a quick inspection.

Annual Service - What It Should Include

Most homeowners don't think about servicing their taps annually - it's something associated with boilers, not fixtures. But a quick annual check-over, particularly if you're in a hard water area like Hampshire, can catch developing problems before they become expensive ones.

A proper annual tap service should cover the following:

1. Inspect and clean all aerators. Remove, descale in white vinegar, and refit. Note any reduction in mesh condition and replace if the mesh is collapsing.
2. Check all isolation valves. Operate each one to confirm it moves freely. Grease or replace if stiff.
3. Inspect all flexi-hoses. Look for kinks, bulging, corrosion at the fittings, or any sign of weeping. Flexi-hoses have a recommended replacement interval of around ten years, though some fail sooner - and a failed flexi-hose can cause thousands of pounds of water damage in a matter of hours.
4. Test tap operation. Check smoothness of operation on all taps, looking for early signs of stiffness or inconsistency that indicate worn internals.
5. Look for signs of leakage under the sink. Check cabinet interiors, pipe runs, and waste connections for damp, staining, or swollen board.
6. Inspect visible seals and O-rings. Replace any that are starting to harden or perish.
7. Check water pressure. High water pressure - anything above 3 bar consistently - causes accelerated wear on tap internals. If pressure is running high at your property, a pressure-reducing valve may well be worth fitting.

For most households, this service takes less than an hour when combined with other plumbing maintenance. Some Portsmouth homeowners include it as part of a broader annual home systems check alongside boiler servicing.

Simple Habits That Extend the Life of Your Taps by Years

The biggest factor in tap longevity isn't what brand you buy - it's what happens after installation. These habits cost nothing and make a measurable difference over time.

Use a water softener or inline filter if you're in a hard water area. Given how hard the water supply is across most of Hampshire, this is one of the most effective things you can do for all your plumbing fixtures - not just taps. A whole-house water softener typically costs between 500 and 1,200 pounds to supply and fit, but it pays for itself through reduced limescale damage across your boiler, taps, shower heads, and appliances.

Don't use abrasive cleaning products on chrome taps. Cream cleaners, scouring pads, and harsh spray products strip chrome plating and create micro-scratches where corrosion starts. Warm soapy water and a soft cloth is all you need for regular cleaning.

Flush new taps through before fitting aerators. When a tap is newly fitted, running it briefly without the aerator catches any debris from the installation before it gets trapped in the mesh. It's a small step that prevents a surprisingly common source of blockage.

Deal with a drip the day you notice it. A dripping tap isn't just wasteful - a tap dripping once per second loses around 12 litres of water per day, adding up to over 4,000 litres per year. More importantly, the drip usually means a washer is failing, and continued use accelerates damage to the tap seat. Fixing it promptly costs far less than fixing it once the seat is gone.

Fit lever handles if you have elderly or young residents. Lever handles require less grip force than traditional cross-head handles, which means less tendency to overtighten - a common cause of washer damage. They're also more accessible for people with limited hand strength or arthritis.

Keep a note of your tap brand and model. When you need parts in ten years, knowing what you've got is the difference between a ten-minute online order and an hour trying to match fittings at a plumbers' merchant. A photo on your phone of the tap and any visible branding is sufficient.

Maintenance Questions

How often should I replace the washers in my taps?

There's no fixed schedule - washers don't need replacing until they show signs of failure, which is typically a drip from the spout. In hard water areas like Portsmouth, washers may deteriorate faster due to limescale and debris working their way into the seal. If a plumber is already on site for other work, it's worth asking them to check washer condition while they're there. Proactive replacement of a worn washer costs very little and prevents the more expensive scenario of a damaged tap seat that needs regrinding or full tap replacement.

Can I fix a leaking tap myself or do I need a plumber?

Replacing a washer on a traditional pillar tap is well within the capability of a competent DIYer - you'll need to isolate the supply, remove the tap head and gland, swap the washer, and reassemble. Modern ceramic cartridge taps are more involved but still manageable if you can identify the correct cartridge part number. That said, if you're not confident isolating the water supply, or if the tap seat feels rough after the washer is out, it's worth calling a plumber rather than risking a more expensive repair down the line.

Why does my tap drip only when the hot side is used?

A drip occurring only on the hot side typically points to a failed washer or cartridge on that specific supply - both sides have independent internals in most mixer taps. It can also occasionally indicate that hot water pressure or temperature is causing expansion that stresses a marginal seal. A plumber familiar with local water conditions across Hampshire can diagnose this quickly, and the Voltrade GoFIX diagnostic process will identify whether the fault sits in the tap or further back in the system, such as at the hot water cylinder or expansion vessel.

How do I know if my tap is beyond economic repair?

The main indicators are visible corrosion or cracking on the body, a drip that returns quickly after a washer change (suggesting tap seat damage), multiple failure points developing at the same time, or parts that are no longer available for your model. If a repair is going to cost more than half the price of a quality replacement tap fitted by a professional, replacement is usually the better long-term decision. A plumber can give you a clear assessment within a few minutes of inspecting the fitting, so it's worth asking before committing to either route.
