Leaking Tap Repair Checklist for Midhurst Homeowners

Published August 2026 | Leaking Tap Repair Guide

This checklist covers every stage of tap maintenance - from the quick visual checks you can run in under ten minutes to the annual professional inspections that catch problems before they turn expensive. Keeping up with regular checks matters because a dripping tap that seems minor can waste thousands of litres of water a year and quietly damage the surfaces, seals, and pipework underneath it.

Quick Visual Checks Anyone Can Do

You don't need to be a plumber to spot the early warning signs of a leaking tap. Run through this list once a week - it takes about five minutes per tap and can save you a significant call-out bill further down the line.

1. Check under the spout for drips at rest. Turn all taps fully off and wait two minutes. Even a slow, irregular drip is worth noting - it typically means a worn washer or O-ring that needs replacing soon.
2. Look for mineral deposits or limescale rings. White or off-white residue around the base of the spout or on the sink surface below it is a clear sign of a slow leak that's been going on for some time.
3. Feel around the tap body and handles for moisture. Run your finger around the base where the tap meets the sink or worktop. Dampness here often points to a failing O-ring in the cartridge or body seal.
4. Test the tap handles for resistance. A handle that moves further than it used to, or that feels loose under your hand, can mean internal wear that leads to dripping. Tight, smooth operation is what you're after.
5. Inspect the flexi hoses under the sink. Open the cabinet under your kitchen or bathroom sink and look at the braided supply hoses. You're looking for bulging, rust staining, or any sign of moisture around the fittings.
6. Check the isolation valve. The small screwdriver-slot valve on the supply pipe should turn freely. If it's corroded or stiff, flag it to a plumber before it becomes an emergency situation.

Monthly Maintenance Tasks

Monthly checks take a bit more attention but are still well within what most homeowners can handle without specialist tools. Our engineers recommend building these into your routine - particularly in older properties across Midhurst where original brass fittings and pipework can degrade faster than in newer builds.

• Run hot and cold through every tap. This keeps cartridges and washers moving and prevents them seizing up, which is a common cause of leaks in taps that are rarely used - guest bathrooms being the typical offender.
• Clean aerators. Unscrew the mesh aerator from the end of the spout and rinse it under running water. A clogged aerator increases back pressure in the tap body, which accelerates wear on the internal seals over time.
• Check beneath baths and basins. Use a torch to inspect the trap, waste pipe, and any accessible supply connections. You're looking for mineral staining, damp patches on surrounding panels, or the smell of mildew.
• Run a simple water pressure check. If you have a pressure gauge (available from most plumbing merchants for around 10 to 15 pounds), attach it to an outdoor tap or the service valve on the rising main. Household water pressure in most West Sussex properties should sit between 1 and 3 bar. Consistently high pressure - above 3.5 bar - puts extra strain on washers and seals and commonly accelerates dripping.
• Log anything unusual. A brief note in your phone about which tap, what you noticed, and the date gives a plumber useful context when you call. It also tells you whether a problem is getting worse month by month.

Annual Professional Checks You Should Book

Some tap and plumbing checks genuinely need a qualified plumber - not because the work is beyond you, but because certain faults are difficult to spot without experience, and getting them wrong can cause more damage than the original problem. Our engineers typically recommend booking an annual plumbing health check, which most plumbers in and around Midhurst offer for between 80 and 150 pounds for a standard residential inspection.

Here's what a professional annual check should cover:

1. Cartridge and ceramic disc inspection. Most modern taps use ceramic disc cartridges rather than rubber washers. A plumber can remove and inspect these for cracks, contamination, or wear that isn't visible from the outside. Cartridge replacement typically costs between 40 and 100 pounds depending on the tap brand and model.
2. Internal valve seat condition. If a washer wears down unevenly, it can score the valve seat beneath it. Once the seat is damaged, replacing the washer alone won't stop the drip. Reseating or replacing the seat requires the right tool and the experience to know when it's needed.
3. Pipework condition check. A plumber will check the visible supply pipework for early signs of corrosion, pin-hole leaks, or failing joints. In West Sussex, properties with older lead or iron pipework benefit from this check most.
4. Stopcock function test. Your main stopcock - the valve that shuts off water to the whole property - needs to close fully and quickly in an emergency. It's not unusual to find stopcocks that haven't been turned in 20 or 30 years and are now partially seized. A plumber can free it off or replace it if needed, typically for between 50 and 120 pounds including labour.
5. Thermostatic mixer service. If you have a thermostatic mixer tap in your shower or bath, the cartridge inside needs periodic flushing and inspection to prevent both dripping and temperature inconsistency during use.

If you'd like to run a preliminary assessment before calling anyone out, the Voltrade GoFIX diagnostic tool can help you identify whether the symptoms you're seeing match a common fault pattern - saving you time when speaking to a plumber and helping you describe the issue accurately.

Warning Signs That Need Immediate Attention

Most tap leaks are slow-burning problems, but some signs mean you should call a plumber the same day rather than waiting for your next scheduled check. Don't leave these until the weekend.

• Water pooling under the sink cabinet. Even a small puddle suggests a failed connection, a cracked flexi hose, or a leaking waste trap. Left overnight, this can cause significant damage to the cabinet base, adjacent flooring, and in two-storey properties, the ceiling below.
• A tap that won't fully turn off. If you can't stop the flow regardless of how hard you turn the handle, the washer or ceramic disc has likely failed completely. Turn off the isolation valve and call a plumber - don't leave it running.
• Discoloured water from the tap. Brown or rust-coloured water points to corroding pipework rather than the tap itself. This needs investigation quickly, as corroded pipes can fail with little further warning.
• Banging or hammering pipes when using a tap. This is commonly called water hammer and can indicate a pressure problem that's putting strain across your whole plumbing system, not just the one tap you're using.
• Visible mould or mildew around the tap base. This suggests a slow leak has been present long enough to create persistent damp conditions behind or beneath the tap. The leak itself may be minor, but the moisture damage underneath can be significant.

Your Maintenance Schedule

A simple calendar makes it easy to stay on top of tap maintenance without letting tasks slip. Here's what our engineers recommend for most homeowners in the Midhurst area:

Older properties - particularly those with original fittings from the 1970s or 1980s - may benefit from moving the six-monthly checks to quarterly, especially during winter when temperature changes put additional stress on seals and joints throughout the system.

Checklist Questions

Have you checked every tap in the property, including outside taps?

It's easy to focus on kitchen and bathroom taps and overlook outside bib taps or utility room fittings. Outside taps are particularly vulnerable in West Sussex winters, where frost can crack seals and split supply pipes. Check them all, and remember to isolate and drain outside taps before the first hard frost each autumn - it's a five-minute job that commonly prevents a much more expensive repair come spring.

Do you know where your main stopcock is and can you turn it off quickly?

In a plumbing emergency, being able to shut off the water supply within 30 seconds makes a real difference to the damage you end up dealing with. Most stopcocks are under the kitchen sink or in the understairs cupboard, but in some Midhurst properties - particularly converted or extended homes - they can be in less obvious locations. Find it now, test that it turns, and make sure everyone in the household knows where it is and what it does.

When did you last have the internals checked on your most-used taps?

Tap internals don't last forever. In a busy household, the kitchen tap cartridge or washer may need attention every three to five years, even if there's no visible drip yet. If you can't remember the last time a plumber inspected the internals of your frequently used taps, add it to your next annual check. Cartridge replacement is typically one of the lower-cost plumbing jobs - commonly between 40 and 80 pounds per tap including labour.

Frequently Asked Questions

How much does it typically cost to fix a leaking tap in Midhurst?

The cost depends on what's causing the drip and the type of tap you have. A simple washer replacement on an older pillar tap is typically one of the cheapest plumbing jobs - often between 50 and 100 pounds including a call-out. Replacing a ceramic cartridge in a modern mixer tap commonly costs between 80 and 150 pounds. If the valve seat is damaged or the tap needs a full replacement, expect to pay between 120 and 250 pounds depending on the fitting you choose and the complexity of the installation.

Is a dripping tap an urgent plumbing problem?

A slow, steady drip isn't usually a same-day emergency, but it shouldn't be left for weeks either. Beyond the water waste, a persistent drip accelerates wear on the valve seat beneath it, which turns a minor repair into a more involved one. If the drip is accompanied by water pooling under the sink, discolouration, or a tap that won't close fully, treat it as urgent and call a plumber straight away rather than waiting for a convenient appointment slot.

Can I fix a leaking tap myself without a plumber?

If you're comfortable turning off the water supply and have basic DIY experience, replacing a rubber washer on an older-style tap is a reasonable task to attempt yourself. Modern ceramic disc cartridges are also replaceable at home if you can identify the correct part for your tap model. That said, if the valve seat is scored, the pipework under the sink looks corroded, or you're not confident about any step of the process, it's worth getting a plumber in - a botched repair on a live supply pipe can cause significantly more damage than the original drip.
