Leaking Tap Repair Checklist for Devizes Homeowners

Published July 2026 | Leaking Tap Repair Guide

This checklist covers everything you need to inspect, maintain, and address when it comes to leaking taps in your home. Catching small drips early saves you from the kind of water damage and inflated bills that our engineers see all too often in Devizes properties.

Quick Visual Checks Anyone Can Do

You don't need tools or plumbing knowledge to spot the early signs of a problem. These checks take less than ten minutes and are worth doing every few weeks.

1. Check the spout for dripping. Turn your tap fully off and watch the spout for 30 seconds. A single drip every few seconds means the internal washer or ceramic disc is worn and needs replacing.
2. Look at the base of the tap. Water pooling around the base when the tap is running points to a failing O-ring on the body of the tap itself.
3. Inspect under the sink. Open the cabinet beneath the basin or kitchen sink and look for moisture, staining, or white limescale deposits on the supply pipes or joints. Wiltshire's water supply is moderately hard, and limescale build-up around joints is a common early indicator of a slow leak.
4. Feel the tap handles. Handles that are stiff, loose, or wobbly suggest wear inside the headwork or a loose packing nut. Both are fixable before they become active leaks.
5. Check your water meter. If you have an accessible meter, note the reading, avoid using any water for an hour, and check again. Any change in the reading when no taps are open suggests a leak somewhere in your supply system.
6. Look at the grouting and sealant around kitchen and bathroom taps. Cracked or missing sealant lets water work its way into the surface beneath, causing silent damage to worktops and cabinets over time.

Monthly Maintenance Tasks

A small amount of regular attention keeps your taps working properly and stops minor wear from turning into a full repair job. These are the monthly tasks our engineers recommend to homeowners across the area.

Run all taps fully. Taps that are rarely used - a bathroom basin in a spare room, for example - can develop stiff seats or seized mechanisms. Run them fully on both hot and cold settings once a month to keep the internal parts moving freely.

Clean aerators. The aerator is the small mesh filter at the end of the tap spout. Unscrew it carefully, rinse it under running water, and soak it in a cup of white vinegar for 20 to 30 minutes if limescale has built up. Blocked aerators put extra back-pressure on the internal washers, accelerating wear.

Check isolation valves under sinks. Each tap has an isolation valve on its supply pipe beneath the sink - the small slotted valves that let a plumber shut off just that tap without turning off the entire water supply. Turn them a quarter-turn each way to make sure they move freely. Valves that seize up become a serious problem in an emergency.

Look for discolouration on surfaces. Rust-coloured staining on enamel basins or around the base of taps suggests prolonged contact with standing water. It often means a drip has been present longer than you realised.

Test your stop tap. Once a month, locate your mains stop tap (typically under the kitchen sink) and confirm it turns. If it's seized, a plumber can free it - usually a quick job costing around 60 to 90 pounds - but you want to know that before you're dealing with a burst pipe.

Annual Professional Checks You Should Book

Some parts of your plumbing need a trained eye rather than a visual scan. Booking an annual plumbing check with a qualified plumber is worth the cost, particularly in older Devizes properties where pipework may be original or where previous repairs have mixed different pipe materials.

An annual professional inspection should cover:

• Full tap service. A plumber will dismantle tap heads, inspect washers, O-rings, and ceramic disc cartridges, and replace any that show wear before they fail. This typically costs between 40 and 90 pounds per tap depending on the tap type and access.
• Inspection of flexible hoses. The flexible braided hoses connecting taps to supply pipes have a limited lifespan, commonly around ten years. Our engineers see these fail without warning in older properties across Wiltshire, and the resulting flood can cause thousands of pounds of damage to floors and cabinets. Replace them proactively rather than waiting for failure.
• Pressure check. Water pressure above 3 bar puts stress on tap internals and pipe joints. A plumber can fit a pressure reducing valve if needed, which protects every tap and appliance in your home.
• Check waste connections and traps. The trap beneath your sink - the curved pipe section - should be inspected for corrosion, cracking, and correct alignment. A slow-leaking trap can rot a kitchen cabinet floor before anyone notices.
• Review of older tap types. If your property still has rising spindle taps (the traditional type with replaceable rubber washers), a plumber may recommend upgrading to ceramic disc taps, which need less frequent servicing and are more resistant to limescale damage.

If you're not sure what condition your plumbing is in before a visit, the Voltrade GoFIX diagnostic tool lets you log symptoms and describe the issue clearly so the plumber arrives knowing what to expect.

Warning Signs That Need Immediate Attention

Some tap and plumbing issues can't wait for a scheduled appointment. Call a plumber promptly if you notice any of the following in your Devizes home.

A tap that won't stop dripping even when turned off as hard as possible. This typically means the washer or cartridge has failed completely. A tap dripping roughly once per second wastes around 15 litres of water per day, which adds up fast on a metered supply.

Water hammering. A banging noise in the pipes when you turn a tap off is caused by a pressure surge. Left unresolved, this can loosen pipe joints throughout your system and cause damage well beyond the tap itself.

Visible corrosion on pipe joints. Green or white crystalline deposits on copper pipe joints under your sink mean the joint is weeping. The deposit forms when water reacts with the pipe material and dries repeatedly, and it gets worse each time water passes through.

Water appearing in unexpected places. Staining on ceilings below a bathroom, damp in kitchen cabinets, or wet patches on walls near pipes almost always indicate a slow leak that has already done some damage. Get it diagnosed quickly - the longer it runs, the more expensive the remediation becomes.

A sudden drop in water pressure from a single tap. This can indicate a blocked aerator or a failing supply valve. If multiple taps are affected at once, contact a plumber or your water supplier, as the cause may be further upstream in the system.

Checklist Questions

How do I know if my tap washer needs replacing?

The clearest sign is a tap that drips from the spout when fully closed. With traditional rising spindle taps, this almost always points to a worn rubber washer. With modern ceramic disc taps, the disc cartridge is the more likely culprit. Either way, the internal component isn't creating a proper seal. You might also notice the tap requires more force to stop the drip than it used to - that's wear getting progressively worse. A plumber can replace a standard washer or cartridge in under 30 minutes, and parts typically cost just a few pounds. Labour for a basic washer replacement in Devizes usually runs between 60 and 90 pounds including the call-out, which is much cheaper than waiting until the drip turns into a constant flow.

Can I fix a leaking tap myself?

If you're reasonably confident with basic DIY and you've isolated the water supply to that tap using the under-sink valve, replacing a tap washer on a traditional rising spindle tap is a job many homeowners manage themselves. You'll need the correct size washer (take the old one to a hardware shop to match it), a pair of adjustable spanners, and a basic understanding of how the headwork goes back together. Ceramic disc cartridges are trickier because the cartridge type varies by tap manufacturer, and fitting the wrong one can cause leaks inside the tap body. If you're at all uncertain, the cost of a professional repair is almost always less than the cost of a botched DIY job that damages pipework or the tap body.

What does a full tap repair typically cost in Wiltshire?

Costs vary depending on the type of tap, the nature of the fault, and whether parts need ordering. As a general guide from our engineers' experience, a standard washer replacement runs between 60 and 90 pounds including labour. Replacing a ceramic cartridge tends to cost between 80 and 130 pounds. Full tap replacement, where the existing tap is removed and a new one fitted, typically costs between 120 and 250 pounds depending on the tap being supplied and the difficulty of access. Emergency call-outs outside normal working hours commonly carry an additional charge of 30 to 60 pounds on top of the standard rate, so it pays to act on warning signs before they become urgent problems.

Frequently Asked Questions

How much water does a dripping tap actually waste?

A tap dripping roughly once per second wastes around 15 litres of water per day, which amounts to over 5,000 litres per year from a single tap. If it's a hot tap, you're also paying to heat that water. On a metered supply, the water cost alone from one persistent drip can add 20 to 40 pounds to your annual bill, not accounting for any surface damage caused by prolonged contact with water around the sink or worktop.

Is it worth repairing an old tap or should I replace it entirely?

In most cases, a repair is the better value option if the tap body itself is in good condition and parts are available. If the tap is heavily corroded, if replacement parts are no longer made for that model, or if it's an older tap that's already been repaired multiple times, replacement makes more sense. A new tap installed by a plumber typically costs between 120 and 250 pounds all in, and a quality modern tap will need considerably less maintenance than an ageing one. Your plumber can advise once they've assessed the existing fitting.

Why does my tap make a whistling or banging noise?

Whistling or squealing when a tap is turned on is commonly caused by a worn or incorrectly sized washer vibrating under water pressure. A high-pitched hum can also point to high water pressure in the system. Banging or hammering when you turn a tap off is usually water hammer - a pressure surge caused by the sudden stoppage of flow through the pipes. All of these are worth raising with a plumber at your next service visit, as each can be resolved fairly quickly once the cause is confirmed.
