Emergency Leaking Tap Repair Guide for Steyning Homeowners

Published September 2026 | Leaking Tap Repair

A dripping or actively leaking tap can cause serious water damage to your home if left unattended - turn off your water supply immediately if water is flowing freely or if you cannot bring the leak under control.

Immediate Actions - Do These NOW

If you've got a leaking tap in your Steyning home, the first few minutes matter. Whether it's a steady drip from a kitchen mixer or water spraying from a loose fitting, here's what you need to do straight away.

Step 1: Find your stopcock and turn off the water

Your stopcock (also called the main stop valve) is typically found under the kitchen sink, in a cupboard beneath the stairs, or near the water meter. Turn it clockwise until it stops. This cuts off your mains supply and immediately stops water flowing to the tap.

If you can't find the stopcock or it won't turn - they can seize up, particularly in older West Sussex properties - look for the isolation valve on the pipework directly feeding the leaking tap. It's a small valve with a flathead screw slot; turn it 90 degrees until the slot runs perpendicular to the pipe.

Step 2: Open the tap to release pressure

Once the supply is off, open the leaking tap fully. This drains any remaining water from the pipe and reduces pressure on the fitting. Keep a towel or bowl underneath to catch what comes out.

Step 3: Contain any water damage

Dry the area around the tap and check whether water has already reached under the sink, into a cabinet, or onto flooring. Place towels down and move anything electrical or valuable out of the way. If water has reached a wall cavity or underfloor space, you need a plumber quickly.

Step 4: Document it before drying up

Take a quick photo or short video before you dry everything up. This helps with fault diagnosis and supports any insurance claim you may need to make.

What NOT to Do

There are a few common mistakes that can turn a manageable leak into a costly repair job. Our engineers see these regularly across Steyning and the surrounding West Sussex area.

Don't ignore a slow drip

A tap that drips once per second wastes a significant volume of water over weeks and months. But the bigger risk isn't the water bill - it's cumulative damage. Water seeping slowly behind tiles, into chipboard under-sink units, or along pipework can cause mould, rot, and structural damage that costs far more to fix than the original tap repair ever would have.

Don't force the tap handle down hard

It seems logical - if it's dripping, tighten it more. But forcing a stiff tap handle hard closed doesn't fix the worn washer or cartridge causing the drip. It typically damages the tap seat or spindle, turning a 50 pound repair into a full tap replacement.

Don't use PTFE tape as a permanent solution

PTFE tape can temporarily slow a weeping threaded joint, but it won't fix a leaking valve seat or worn cartridge. Wrapping tape around things and hoping for the best usually just delays the inevitable - and sometimes makes the repair harder when a plumber does arrive, because fittings become harder to dismantle cleanly.

Don't attempt to solder pipework without the training

If the leak is coming from the pipework rather than the tap itself, leave it. Soldering copper pipe incorrectly can weaken joints, and misapplied push-fit connectors can cause a larger failure downstream. This is a job for a qualified plumber.

Don't use chemical sealants in drinking water lines

Some products marketed as "pipe sealers" are not suitable for use in potable water systems. If the tap is on your cold water drinking supply, only approved materials and fittings should be used. When in doubt, ask the plumber.

When This Is a Genuine Emergency vs When It Can Wait

Not every leaking tap is a crisis, but knowing the difference helps you decide whether to call someone out of hours or book for the next available slot.

Treat it as an emergency if:

• Water is spraying or flowing freely and you cannot stop it by turning off the stopcock
• The stopcock itself is leaking or won't turn at all
• Water is near any electrical installation, fuse board, or socket
• There is visible water damage spreading quickly - saturated floorboards, water appearing through a ceiling below
• The leak is from a hot water pipe and your boiler is cycling repeatedly trying to maintain pressure

In any of these situations, call a plumber immediately. Emergency call-outs to Steyning can typically be attended within a few hours depending on availability and time of day.

It can wait until normal hours if:

• You've successfully isolated the tap and the drip has stopped completely
• The drip is very slow and contained - a cloth underneath is managing it overnight
• There's no sign of water reaching joinery, flooring, or electrical fittings
• The affected tap is a secondary one you don't need urgently - a guest bathroom, outside tap, or utility room

If it can wait, use the Voltrade GoFIX diagnostic tool to describe your fault before the plumber arrives. It helps narrow down whether you're dealing with a washer replacement, a cartridge swap, or something more involved, so the engineer can arrive with the right parts.

Getting Emergency Help in Steyning

Steyning is a market town in the Adur district, and while it's not a large urban centre, there are qualified plumbers able to cover emergency call-outs to the area. Response times vary - arriving within two to three hours is realistic during business hours, and three to five hours for evening or weekend emergencies.

When you call, have the following ready:

• The type of tap - mixer, pillar tap, quarter-turn lever, or monobloc kitchen tap
• Where in the house the fault is and whether you've already isolated the supply
• Whether the leak has stopped or is still active
• The approximate age of the property, since older homes in Steyning can have imperial-sized fittings or lead pipework that need specific parts sourced in advance

Emergency plumbing call-outs in West Sussex typically cost between 80 and 160 pounds for the call-out fee alone, depending on the time of day and day of the week. Labour and parts are charged on top. A washer replacement on a standard tap might add 30 to 60 pounds; replacing a ceramic cartridge in a modern mixer tap commonly costs 40 to 80 pounds including the part. If the tap itself needs replacing, expect to pay between 150 and 350 pounds in total, depending on the tap you choose and the complexity of the installation.

Always ask whether the call-out fee is included in the total estimate or charged separately before the engineer starts work. Any reputable plumber will be upfront about this.

What the Emergency Repair Involves

Understanding what a plumber will actually do helps you know whether the job is progressing correctly and what to expect.

Diagnosing the fault first

The most common causes of a dripping tap are a worn rubber washer (on older pillar and crosshead taps), a damaged ceramic cartridge (on most modern mixer taps), or a failed O-ring on the tap body. Our engineers start with a visual inspection and isolate the tap fully before dismantling anything.

Repairing a traditional washer-type tap:

1. Isolate the water supply and open the tap to drain the pipe
2. Remove the tap handle and cover plate to expose the headgear
3. Unscrew the headgear assembly with a spanner
4. Replace the rubber washer at the base of the headgear, and the O-ring if it's also worn
5. Reassemble, restore the supply, and test fully

This repair typically takes 30 to 45 minutes on a standard domestic tap.

Repairing a ceramic cartridge mixer tap:

1. Isolate both hot and cold supplies feeding the mixer
2. Remove the handle - usually held by a grub screw under a decorative cap
3. Extract the cartridge using a cartridge puller or careful manipulation
4. Fit a matching replacement cartridge - brands like Grohe, Hansgrohe, and Bristan have widely available cartridges, while lesser-known brands can need parts ordered in
5. Reassemble, restore the supply, and test for leaks

This takes 45 minutes to an hour, longer if the cartridge is a less common size or if there's corrosion on the fittings.

When the tap seat is damaged

On older taps, the brass seat the washer presses against can corrode or pit over time. A plumber will use a tap reseating tool to grind the surface smooth, or replace the seat insert. If the damage is too severe, a full tap replacement is the more practical route and typically works out better value in the long run.

Your Emergency Tap Repair Questions Answered

How much does an emergency leaking tap repair cost in Steyning?

Emergency plumbing call-outs in the Steyning area typically carry a call-out charge of between 80 and 160 pounds, with labour and parts charged on top. A washer replacement might bring the total to around 120 to 180 pounds. More complex jobs - replacing a cartridge, reseating the tap, or fitting a new tap entirely - commonly come to between 180 and 350 pounds depending on parts and time taken. Always confirm the total estimated cost before the engineer starts work, including whether the call-out fee is separate.

Can I fix a dripping tap myself before calling a plumber?

If you're confident isolating the water supply and have the right tools, replacing a rubber washer on a traditional crosshead tap is within reach for a capable DIYer. Ceramic cartridge repairs are more involved - you need the correct replacement part for your specific tap model, which isn't always easy to identify. If you're not sure what you're dealing with, it's better to isolate the supply and call a plumber rather than risk damaging the tap body or the pipework beneath. Poorly attempted DIY repairs can significantly increase final costs.

Is a dripping tap covered by home insurance?

Most standard home insurance policies don't cover general wear and tear, which is typically how insurers classify a dripping tap caused by a worn washer or cartridge. However, if the leak has caused consequential damage to flooring, ceilings, or cabinetry, that resulting damage may be claimable depending on your policy wording. Document any damage with photographs before repairs are made. Some home emergency cover add-ons do include plumbing call-outs, so it's worth checking whether you have this as part of your policy.

Why does my tap only drip when the heating is on?

This is commonly caused by thermal expansion in the pipework, or a failing cartridge that becomes less effective as water temperature rises. In some cases it points to a pressure issue in the hot water system - as water expands with heat, it can push past a worn seal that holds fine at lower pressure. A plumber attending in Steyning will typically check system pressure and the condition of the expansion vessel as part of diagnosing this, since it can sometimes indicate a wider hot water system issue rather than just a tap fault.
