Leaking Tap Repair Checklist for Derby Homeowners

Published July 2026 | Leaking Tap Repair Guide

This checklist covers the key checks, maintenance tasks, and warning signs every homeowner needs to know when it comes to leaking taps. Catching problems early - whether it's a worn washer or a failing cartridge - can save you from expensive water damage and a water bill that creeps up for no obvious reason.

Quick Visual Checks Anyone Can Do

You don't need tools or plumbing experience to spot the early signs of a failing tap. These checks take under five minutes and could save you a call-out fee if you catch something before it develops into a bigger problem.

1. Check for visible drips at the spout. Turn the tap fully off and watch the spout for 30 seconds. Even one drip every few seconds adds up to several litres of wasted water per day - and over a month that becomes a meaningful amount.
2. Look at the base of the tap body. Water pooling around the base, or a white limescale crust building up at the edge, often means the O-ring or gland packing is starting to fail.
3. Test the handle or lever for movement. If there's wobbling, or the handle feels noticeably loose, the headgear assembly is likely worn. In Derby's older housing stock - particularly Victorian terraces and inter-war semis - this is very common.
4. Open the cabinet and look under the sink. Damp patches, rust stains, or a faint musty smell point to a slow leak at a compression fitting or supply hose connection.
5. Check the tap body for cracks. On ceramic or chrome taps, hairline cracks can develop around the spout or body. These worsen quickly and typically mean the tap needs replacing rather than repairing.
6. Run the cold and hot sides separately. A tap that only drips when the hot is on usually has a problem on the hot side - often a washer that's been degraded by years of heat exposure.
7. Check the wall or surface behind the tap. Discolouration, soft plaster, or swollen worktop material behind a sink or bath tap is a sign that water has been reaching somewhere it shouldn't.

Monthly Maintenance Tasks

Monthly maintenance doesn't need to take long, but it's worth building into your routine - especially in parts of Derbyshire where harder water causes limescale to accumulate faster than homeowners often expect.

Clean aerator screens. The aerator - the small mesh fitting at the end of most modern tap spouts - collects limescale and debris over time. Unscrew it monthly, rinse it under running water, and soak it briefly in white vinegar if there's noticeable build-up. A blocked aerator forces the tap mechanism to work harder, which accelerates wear on internal components.

Exercise isolation valves. The small valves on the supply pipes under your sinks and baths should be turned off and back on once a month. Valves that sit fully open for years can seize, meaning that if you ever need to isolate the water quickly - which is exactly when you need them to work - they won't. A quarter turn off and back on is all it takes to keep them free.

Check all handles for early stiffness. A tap that's becoming harder to turn is usually telling you the washer or cartridge is on its way out. Catching it at this stage typically means a simple part replacement rather than a full tap change.

Wipe down tap bodies. Use a mild cleaner - nothing abrasive on chrome or brushed steel finishes. Keeping the surface clean makes it easier to spot new cracks or corrosion that might otherwise hide under limescale deposits.

Note any change in flow or pressure. If one tap has dropped in pressure while others haven't, it can indicate a partial blockage or a failing cartridge. In some properties with older pipework, fluctuating pressure can stress tap components over time - worth flagging to a plumber if it persists.

Annual Professional Checks You Should Book

Some tap issues need a trained plumber with the right tools to assess properly. An annual check is especially worthwhile for older properties, or if you've had any work done to the plumbing in the past year.

Here's what our engineers typically cover during a professional tap inspection:

1. Full washer and cartridge assessment. Washers in traditional pillar taps typically last five to ten years depending on usage and water quality. A plumber will test the condition of every tap in your home and replace worn washers before they fail completely.
2. Gland packing inspection. The gland packing prevents water from leaking up through the spindle. It can be re-packed or replaced on most older taps without needing a full unit replacement.
3. Main stopcock test. Your stopcock - usually under the kitchen sink or where the supply enters the property - needs to be confirmed fully functional. A stopcock that fails in an emergency means you can't isolate the water supply to the whole house.
4. Pipework check around tap connections. Engineers inspect for early corrosion, movement in compression joints, and any signs that past DIY repairs aren't holding under normal operating pressure.
5. Water pressure assessment. Mains pressure in Derby typically runs between 1 and 3 bar. Properties at the end of long supply runs can sit below this, which affects how taps and appliances perform. A plumber can test this and advise whether a booster pump is worth considering.
6. Logged condition report via GoFIX. Voltrade engineers use the GoFIX diagnostic tool to log the condition of each tap and associated pipework, giving you a clear record of what was checked and what needs monitoring going forward.

A routine annual visit of this kind typically costs between 70 and 130 pounds depending on the number of taps and the complexity of the pipework involved. That compares well against the cost of water damage repair, which commonly runs to 500 pounds or more once you factor in drying out, replastering, and redecoration.

Warning Signs That Need Immediate Attention

Most tap issues can wait for a scheduled appointment. These ones can't. If you spot any of the following, stop using the tap and contact a plumber the same day.

• Water coming from the wall or floor near the tap. This points to a burst or severely failing connection behind the tiles or under the floor. Turn off the isolation valve immediately if it's accessible.
• A tap that won't close at all. If the handle spins freely with no resistance, the headgear has failed. You'll need to shut off the mains supply until a plumber can replace it.
• Discoloured or brown water. This can sometimes follow work on the mains supply in your area, but it can also point to internal corrosion in your pipework. Don't use the water for drinking or cooking until you've established the cause.
• A sudden pressure drop across multiple taps. A widespread drop could indicate a problem on the mains, a failed pressure regulator, or a significant leak somewhere in the system.
• Visible mould around a tap base. Mould growth means water has been sitting in a damp patch for some time. It's typically a sign a slow leak has been active far longer than you realised.
• Any leak near an electrical fitting. Water near a socket, light fitting, or appliance is a serious safety issue. Turn off the water and the relevant circuit breaker, and call a professional before doing anything else.

Your Maintenance Schedule

Building these tasks into a simple calendar is the most reliable way to stay on top of things without having to rely on memory.

Properties built before the 1980s benefit most from frequent checks. Older copper pipework and period fittings can carry hidden vulnerabilities that a newer build simply doesn't have, and the gap between a minor issue and an expensive leak can be shorter than you'd expect.

Checklist Questions

How much does a leaking tap repair cost in Derby?

The cost depends on the type of tap and what's failed. A washer replacement on a traditional pillar tap typically costs between 50 and 100 pounds all-in, including the call-out. A ceramic disc cartridge replacement - common in modern mixer taps - usually runs between 80 and 150 pounds. If the full tap needs replacing, expect to pay between 120 and 280 pounds for labour, on top of the cost of the tap itself. Calling a Derbyshire-based plumber for an initial assessment is always worth doing before assuming everything needs to come out.

Can I fix a leaking tap myself, or should I call a plumber?

Replacing a washer on an older pillar tap is something a confident DIYer can usually manage, provided you can isolate the supply at the isolation valve or mains stopcock. But if the tap uses ceramic cartridges, if the headgear is corroded in place, or if there's any sign of a leak behind the fittings rather than at the tap itself, call a professional. Attempting a repair you're not comfortable with can cause more damage - and in older Derbyshire homes where pipework hasn't been touched for decades, disturbing corroded fittings without knowing what you're doing can turn a simple job into a considerably larger one.

How do I know if my tap is dripping because of a faulty washer or low water pressure?

Low water pressure typically affects multiple taps across your home at once and usually shows up as reduced flow rather than a persistent drip. A faulty washer or worn cartridge tends to cause a drip at one specific tap - particularly noticeable when the tap is turned fully off. If you're unsure, our engineers can run a pressure test and inspect the tap's internal components in a single visit. The Voltrade GoFIX diagnostic tool logs both pressure readings and component condition together, so you get a complete picture rather than just a fix for the immediate symptom.
