Leaking Tap Repair Guide for Torquay Homeowners

Published September 2026 | Leaking Tap Repair

You noticed the drip a few days ago - just a slow beat from the kitchen mixer tap you told yourself you'd deal with at the weekend. Now it's Tuesday evening, the sound is louder, and there's a rust-orange stain forming around the plughole. If you're in a Torquay property, you're not alone: leaking taps are one of the most common plumbing calls our engineers attend across Devon every single week.

What's Actually Happening When a Tap Leaks

A leaking tap isn't just an annoyance - it's your plumbing system telling you something has worn out or failed. Inside every tap there's a mechanism that controls the flow of water. When that mechanism can no longer form a watertight seal, water finds the path of least resistance, usually back out through the spout, around the base, or from the handle itself.

The water mains in most UK properties are under constant pressure, typically between 1 and 3 bar in domestic homes. That pressure doesn't switch off when you turn the tap handle - it's always there, pushing against whatever seals are inside. Over time, those seals break down. It's not dramatic. It's just physics and wear.

Understanding which part of the tap is leaking is the first step to fixing it properly. Our engineers use the Voltrade GoFIX diagnostic tool to log the fault type and tap make before attending a job, which means arriving with the right parts rather than making multiple trips back to the merchant.

The Most Common Causes of a Leaking Tap

There are several distinct failure points in a tap. Each one has different symptoms and requires a different fix. Getting this diagnosis right is what separates a lasting repair from one that fails again in three weeks.

Worn Washers

The most common cause of a dripping tap is a worn or damaged washer. Traditional pillar taps - the kind with separate hot and cold controls - use a rubber or fibre washer pressed against a valve seat every time you turn the tap off. Do that tens of thousands of times over several years and the washer eventually compresses, cracks, or hardens. The seal becomes imperfect and water starts to get through.

When the washer goes, you'll typically see a steady drip from the spout even with the tap fully closed. The drip is usually constant rather than intermittent. Replacing a washer is one of the simpler plumbing jobs, but it does require isolating the water supply first, and the right washer size matters more than most people expect.

Faulty O-Rings

O-rings are small rubber rings that create a seal around the spindle - the rotating part connected to the handle. When they deteriorate, water leaks from the handle itself or from the base of the spout rather than from the spout opening. This kind of leak is particularly common in mixer taps, especially older chrome-finished units you find in many Torquay period properties.

O-rings harden with age, and certain limescale cleaning products accelerate that process considerably. If you're noticing water pooling at the base of your tap when it's in use, a faulty O-ring is a very likely culprit.

Corroded or Pitted Valve Seat

The valve seat is the connection point between the tap body and the spout. Over time, sediment deposits from hard water can corrode or pit the valve seat surface, meaning that even a brand-new washer won't form a proper seal against it. Devon water is generally considered moderately hard in coastal areas, and mineral build-up is a genuine issue in Torquay properties - particularly in kitchens and bathrooms that haven't had any filtration fitted.

If you've already replaced a washer and the tap still drips, a damaged valve seat is usually the next thing to investigate. It's a step that often gets skipped, which is why some homeowners find themselves repeatedly replacing washers on the same tap.

Loose Packing Nut

The packing nut sits just below the handle and holds the stem securely in place. A packing nut that's worked loose over time allows water to seep up around the stem and drip from around the handle rather than the spout. This type of leak is sometimes mistaken for condensation. It can often be resolved by carefully tightening the packing nut, though worn packing material inside may need replacing as well.

Failed Ceramic Disc Cartridge

Many modern taps - particularly quarter-turn lever taps and contemporary mixer designs - use ceramic disc cartridges instead of traditional rubber washers. These are more durable than rubber, but they're not indestructible. Grit in the water supply, mineral deposits, or a manufacturing defect can cause the ceramic discs to crack or chip, allowing water to pass through when the tap should be closed.

Ceramic disc failures often show up as a tap that won't fully close, or one that leaks more noticeably when the water is cold. These cartridges typically need to be replaced rather than repaired, and sourcing the correct one for your specific tap brand can take a bit of research.

Solutions That Actually Work

The right solution depends entirely on what's causing the leak. Here's what our engineers actually do on a repair call, broken down by fault type.

Isolate the water supply first. Before any work starts, the supply to the affected tap needs to be shut off. This is usually via an isolation valve on the supply pipe (look for a flat-head screw slot on the pipe under the sink - turn it 90 degrees). If there's no isolation valve, or it's seized, you'll need to turn off the mains stop tap, which in most Torquay houses sits under the kitchen sink or in a cupboard near the front of the property.

Replacing a washer:

1. Turn off the water supply and open the tap fully to release any pressure in the line.
2. Remove the tap handle - usually held by a screw hidden under a decorative cap on top.
3. Use an adjustable spanner to remove the headgear nut (turn anticlockwise).
4. Pull out the jumper valve or spindle and locate the washer at the base, often held by a small nut.
5. Replace the old washer with an identical-size replacement and reassemble in reverse order.
6. Turn the water back on slowly and test through several open-and-close cycles.

The washer itself costs very little - typically under 5 pounds for a mixed pack - but getting the right diameter is essential. Our engineers carry a full range of sizes and washer types for exactly this reason.

Replacing an O-ring follows a similar disassembly process. Once you've located the worn ring on the spindle, replace it with one of the correct diameter. Applying a small amount of silicone grease to the new O-ring before fitting helps it seat properly and extends its service life.

Reseating a valve seat requires a specialist tool called a tap reseater, which grinds away the pitted surface to create a smooth face for the new washer to press against. This is not a tool most homeowners keep to hand, and using it incorrectly can worsen the damage. If the seat is badly corroded, replacing the whole tap is sometimes the more economical choice.

Replacing a ceramic cartridge means removing the handle and retaining screw, pulling out the old cartridge, and fitting a new one in the same orientation. The tricky part is sourcing the correct cartridge for your tap brand. Less common brands use proprietary cartridges that can take several days to arrive. Our engineers check the Voltrade GoFIX system for tap model details before the visit to confirm part availability ahead of time.

When to Fix It Yourself and When to Call a Plumber

Not every leaking tap needs a professional. A dripping pillar tap with a worn washer is a job many confident DIYers can manage with basic tools. But there are situations where attempting the repair yourself can create a more expensive problem.

You can probably manage it yourself if:

• The tap is a traditional pillar tap with separate hot and cold controls
• You can easily isolate the water supply with a working isolation valve
• The drip is from the spout rather than the tap body or the connections beneath
• You're comfortable with basic disassembly and have the right tools to hand

Call a plumber if:

• The leak is from the supply pipes beneath the tap rather than the tap itself
• There's no isolation valve, or it's seized and won't turn
• The tap is a complex mixer, thermostatic, or pull-out spray type
• You've already attempted a fix and the drip has returned
• There are signs of water damage to the cabinet below - swollen chipboard, mould, or discolouration
• The tap components are seized and won't move without significant force

In Devon, many older properties have plumbing that dates back decades and supply pipes in genuinely awkward locations. Working on ageing systems without plumbing experience carries a real risk of cracking older pipework or stripping corroded fittings, which turns a modest repair into a much larger job. If in doubt, a call-out to diagnose the issue properly is money well spent.

What to Expect from a Repair Visit

When one of our engineers attends a leaking tap call in Torquay, the process is fairly consistent. Here's what typically happens from arrival to sign-off.

The visit starts with a visual inspection to confirm where the leak is coming from and to check the condition of the surrounding plumbing and isolation valves. We check that the isolation valve is operational before starting, because a seized valve can change the scope of the job - if we can't isolate the supply locally, we need to turn off the mains, which may affect other areas of your home.

Most standard washer or O-ring replacements take between 30 minutes and an hour, including reassembly and testing. We run the tap through several cycles before leaving to confirm the seal is holding properly.

Ceramic cartridge replacements depend on parts availability. If we carry the right cartridge for your tap model, the visit takes a similar amount of time. If the cartridge needs to be ordered, a second visit will be required.

Typical costs for a leaking tap repair in the UK:

• Call-out and basic washer replacement: typically between 80 and 150 pounds including labour
• Ceramic cartridge replacement: typically between 100 and 180 pounds depending on parts and tap make
• Full tap replacement where the existing tap is beyond economic repair: typically between 150 and 300 pounds including the new tap, depending on fitting complexity and the tap you choose

These figures reflect standard residential work. Prices vary depending on time of day, whether weekend call-out rates apply, and what's discovered once the tap is opened up. It's worth asking your plumber to confirm any additional costs before work begins if the initial inspection reveals something unexpected.

Common Questions from Torquay Homeowners

How much water does a dripping tap actually waste?

A tap dripping once per second wastes roughly 5,500 litres of water per year - around 5 to 6 cubic metres. In practice, most dripping taps run faster than one drip per second, so the actual figure is commonly higher. If you're on a water meter in Torquay, a persistently dripping tap will typically add a noticeable amount to your quarterly bill, often more than the cost of getting it repaired. Fixing it promptly is almost always cheaper than ignoring it.

Can I use sealant or tape to temporarily stop the leak?

PTFE tape and plumber's putty have legitimate uses in proper plumbing repairs, but applying sealant to the outside of a leaking tap as a temporary patch rarely works and can make the eventual correct repair harder. The leak is almost always caused by a worn internal component. Covering the outside changes nothing about what's happening inside. Replacing the faulty washer, O-ring, or cartridge is the only reliable fix.

Why does my tap only leak when the water is hot?

This is a common symptom and it typically points to a washer or O-ring that has hardened unevenly. Hot water causes metal tap components to expand slightly, changing the pressure against a worn seal in a way that cold water doesn't replicate. It's also possible that your hot supply is at marginally higher pressure than the cold. Either way, the fix is the same - replacing the worn sealing components - but the symptom is useful information for diagnosing which part is at fault.

How long should a tap washer or cartridge last?

A rubber washer in a regularly used tap commonly lasts between 5 and 15 years, depending on water quality and how firmly the tap is closed each time. Local water in coastal areas and the mineral content it carries can accelerate wear on rubber components. Ceramic disc cartridges typically last longer - often between 10 and 20 years - but they're more susceptible to damage from grit or sediment in the supply. Turning taps off gently rather than forcing them closed is one of the most effective ways to extend washer life.
