Leaking Tap Repair Guide for Melksham Homeowners

Published August 2026 | Leaking Tap Repair

In the first 10 minutes

A leaking tap left running wastes more water than most people realise. Even a slow drip - one drop per second - can lose thousands of litres a year. But beyond the water bill, a tap leaking under pressure can cause damp, mould, and lasting damage to cabinets and worktops if ignored long enough.

Here's what to do right now:

1. Find the isolation valve under the sink or basin. It's a small slotted screw - turn it 90 degrees with a flat-head screwdriver until the slot runs across the pipe, not along it. That isolates just the one tap without cutting water to the whole house.
2. If there's no isolation valve, go straight to the mains stopcock. In most Melksham homes, this sits under the kitchen sink. Turn it clockwise to close it.
3. Open the tap fully to drain any remaining pressure from the pipe.
4. Dry the area around the tap base and the inside of the cabinet with an old towel. Note where the water is actually coming from - spout, handle, base, or the supply pipes - because this tells you a lot about what's failed.
5. Don't force a stiff tap handle. You risk snapping the spindle or cracking an older ceramic fitting, which turns a minor repair into a bigger one.

If water is tracking down from the pipe joints rather than the tap itself, keep the area dry and take the pressure off those joints until a plumber can assess them.

Within the first hour

Once the water is off, take stock of what you're dealing with. Most tap leaks fall into one of four categories, and identifying which one you have helps your plumber arrive prepared.

Dripping from the spout is typically a worn washer or ceramic disc inside the tap body. This is the most common fault our engineers see in Melksham properties, and it's usually the most economical to fix.

Leaking from the base of the tap usually points to a worn O-ring around the tap body. Water tracks down and pools on the worktop or basin surround, often causing damage before anyone notices.

Leaking from around the handle commonly means the gland packing or O-ring around the spindle has dried out or deteriorated. You'll see water seeping out each time the tap is turned.

Leaking from pipe connections could be a loose compression fitting or failed PTFE tape on a threaded joint. This one needs a plumber rather than a DIY attempt.

Take a few photographs on your phone before you touch anything further. This is useful when getting a quote - you can share images via the Voltrade GoFIX diagnostic tool to get an initial assessment and avoid unnecessary callout charges.

If you're a tenant, call your landlord or letting agent now. They're responsible for arranging and funding plumbing repairs in most standard tenancy agreements. If you own the property, you'll need to decide whether this is a job for a confident DIYer or a professional. A washer swap on an old pillar tap is manageable with basic tools. A monobloc mixer, a quarter-turn ceramic tap, or anything involving the supply pipework is best left to someone who does it every day.

Same day

Getting help booked quickly matters in Wiltshire - particularly through autumn and winter, when increased demand and pipe pressure can turn a minor drip into something more serious. When you call a plumber, have the following to hand:

• The type of tap - pillar, monobloc mixer, bath mixer, or quarter-turn
• Approximate age of the tap if you know it
• Where the leak is coming from
• Whether the supply is already isolated
• Any photos you've taken

Most reputable plumbers serving Melksham will charge a fixed callout rate plus parts. For a standard tap repair, expect to pay somewhere between 80 and 150 pounds for labour, with parts adding roughly 5 to 40 pounds depending on the tap type. A rubber washer costs almost nothing; a ceramic cartridge for a premium mixer tap can run to 30 or 40 pounds for the part alone. If the tap is older and parts are no longer available, a plumber may recommend replacement rather than repair. A new tap supplied and fitted typically costs between 150 and 300 pounds depending on the quality and style chosen.

While you wait, don't leave the whole property without water if you can avoid it. If the faulty tap has its own isolation valve and the rest of the house is unaffected, turn the mains back on. There's no need to deprive the whole household.

The repair visit

Here's what to expect when a plumber arrives to carry out a leaking tap repair in a Melksham home.

The first thing they'll do is confirm the isolation and check there's no residual pressure before opening anything up. Then the process typically goes like this:

1. Remove the tap handle - usually held by a grub screw hidden under a decorative cap or index disc
2. Remove the headgear using an adjustable spanner - this is the core mechanical unit of the tap
3. Inspect the washer, O-ring, or ceramic disc cartridge and replace whichever component has failed
4. If the tap seat is damaged - the brass surface the washer presses against - the plumber may re-seat it using a tap reseating tool rather than recommending a full replacement
5. Reassemble, restore the water supply, and test under full pressure
6. Check all joints and connections for any sign of weeping once flow is restored

A typical repair takes between 30 minutes and an hour for a washer or cartridge replacement. Tap reseating adds time but often saves the cost of a new tap. If a cartridge is an unusual size or the tap uses a non-standard part, a plumber may need to order it and return for a second visit - another reason to book early in the day so there's time to source parts locally.

If your tap body is cracked, the headgear threads are corroded beyond use, or the tap is so old that parts are simply unavailable, your plumber will explain the replacement options clearly before proceeding.

The following week

After the repair, spend a few minutes over the next couple of days checking everything is holding as it should.

Run both hot and cold through the repaired tap and watch the spout carefully after closing it. A properly repaired tap should stop flow completely - no slow drip, no trickle. If there's still a drip, something hasn't seated correctly and the plumber needs to know.

Check inside the cabinet with a torch. Look at the flexi hoses connecting the tap tails to the supply pipes. These braided metal hoses are a very common independent failure point, and if they're showing any swelling, rust staining at the end fittings, or signs of weeping, they should be replaced soon. A burst flexi hose can release a significant volume of water in a very short time - our engineers see the results of this regularly in Wiltshire properties, and it's usually far more disruptive than the original tap issue.

Also check that the isolation valves are open fully, that the tap handle moves without wobble or resistance, and that there are no damp patches remaining inside the cabinet. Most reputable plumbers offer a guarantee on their labour - typically 30 days as a minimum, sometimes considerably longer.

Long term

Most tap failures in Wiltshire homes come down to two things: water hardness and wear over time. Melksham sits in an area with moderate to high water hardness. Limescale accumulates inside tap bodies, on washers, and across ceramic discs, accelerating wear and reducing the working life of fittings.

For long-term tap health, consider the following:

• Don't overtighten taps when closing them. The old habit of forcing a tap fully shut damages washers faster than normal everyday use ever would.
• If a tap starts squeaking or stiffening up when turned, that's an early warning sign. A small amount of plumber's grease applied at that stage can defer a full repair by years.
• Ask your plumber to check tap washers during any annual boiler service visit to your Melksham property. It takes only a few minutes and can catch early wear before it becomes a drip.
• Fitting an inline water softener or under-sink scale inhibitor can significantly extend the life of taps, shower fittings, and boiler components throughout the home.
• If you're replacing taps as part of a kitchen or bathroom renovation, buy from brands with solid UK parts availability. Budget imports often use non-standard cartridges that become difficult or impossible to source. Brands such as Bristan, Grohe, and Hansgrohe have better aftermarket parts support than many cheaper alternatives.
• Keep a note of your tap brand and model number somewhere accessible - the inside of a cupboard door works well. When something fails, your plumber can order the correct cartridge before arriving rather than making multiple trips.

Timeline questions

How long does a leaking tap repair take in Melksham?

Most tap repairs take between 30 minutes and an hour once a plumber is on site. A simple washer replacement sits at the quicker end of that range. If the tap needs reseating or the cartridge is an unusual size that has to be ordered, the job may require a second visit. Booking early in the day gives the plumber the best chance of sourcing any parts locally on the same day.

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

A rubber washer replacement on an older pillar tap is manageable for a confident DIYer with basic tools and the water isolated correctly. Modern monobloc mixer taps and quarter-turn ceramic disc fittings are more involved - cartridge types vary widely between manufacturers, and fitting the wrong one will fail quickly. If there's any doubt, a plumber will save you time and avoid turning a minor repair into a bigger problem.

What does a leaking tap repair cost in Wiltshire?

In the Melksham area, expect to pay between 80 and 150 pounds for labour on a standard tap repair, plus the cost of parts. A washer kit typically costs under 5 pounds; ceramic cartridges range from around 10 to 40 pounds depending on the tap brand and model. A full tap replacement - supply and fit - commonly runs between 150 and 300 pounds. Always ask for a fixed quote before work begins.

What happens if I ignore a leaking tap?

A dripping tap adds to your water bill if you're on a meter, but the bigger risk is water damage. A tap leaking at the base or through supply connections causes ongoing damp inside kitchen or bathroom cabinets, which leads to mould growth, swollen woodwork, and eventually damage to flooring and structural materials. What starts as a quick repair at under 100 pounds can become a multi-hundred-pound remediation job if left long enough.
