Leaking Tap Repair Guide for Eastbourne Homeowners

Published July 2026 | Leaking Tap Repair

Most people think a dripping tap is a five-minute job - grab a new washer from the hardware shop, tighten a few things, done. It is one of the most persistent myths in home maintenance, and it is responsible for more wasted water, damaged pipework, and expensive call-outs than almost any other DIY misconception. If your tap is dripping, the truth is a bit more involved than the internet would have you believe.

Myth: A New Washer Will Fix Any Leaking Tap

The Reality

This is the big one. The rubber washer fix works well - but only on a specific type of tap: the traditional pillar tap with a rising spindle. These are the older-style taps where the handle rises as you turn it. A new washer on this type of tap can absolutely stop a drip.

The problem is that a large proportion of taps fitted in UK homes over the past 20 to 30 years use ceramic disc cartridges instead. Quarter-turn taps, modern mixer taps, monobloc kitchen taps - almost all of them rely on two ceramic discs that rotate against each other to control water flow. There is no rubber washer to replace. If you try to fit one where it does not belong, you will either achieve nothing or introduce a new leak.

Our engineers use the Voltrade GoFIX diagnostic tool to identify tap type before touching anything. It takes two minutes and means you buy the right parts first time rather than making three trips to the hardware shop. In Eastbourne, where a lot of the housing stock mixes Victorian-era plumbing with more recent upgrades, you simply cannot assume what is inside a tap until you look.

When the ceramic discs themselves are worn or chipped - which is common in hard water areas - you typically need to replace the whole cartridge. Cartridges vary enormously by manufacturer and tap model. The wrong cartridge will either not fit or will leak worse than before.

Myth: Turning the Tap Off Harder Will Stop the Drip

The Reality

We hear this one constantly. The logic seems sound - if water is getting through, force it shut. In practice, cranking a tap handle down as hard as you can is one of the more effective ways to destroy a tap from the inside.

On washer-based taps, the rubber washer presses against a brass valve seat. Over-tightening crushes and distorts the washer, scoring grooves into the valve seat below it. Once the seat is scored, no new washer will seal properly against it - you have now created a more complex repair than you started with. Valve seat regrinding tools exist, but using one correctly requires experience. It is an extra step and extra cost that did not need to happen.

On ceramic disc taps, forcing the handle causes a different problem. The ceramic discs are hard but brittle. Excessive torque can crack them, at which point you are looking at water hammering out rather than a steady drip. The repair bill goes up significantly.

If your tap is dripping despite being turned off at normal hand pressure, the tap needs attention. Eastbourne plumbers typically charge between 80 and 120 pounds for a standard tap repair call-out, which is far less than the cost of replacing a damaged tap body entirely.

Myth: PTFE Tape Will Fix a Leaking Tap

The Reality

PTFE tape - that white thread-seal tape you will find in every plumber's toolkit - is a useful product. But it is useful for one specific job: sealing threaded joints on pipework and fittings. It is not a fix for a dripping tap spout.

PTFE tape goes around the threads of pipe fittings to create a watertight seal between metal surfaces that screw together. It does nothing for a tap that is dripping from the spout. If your kitchen tap is producing a steady drip, wrapping PTFE around the base connection will not touch the actual fault, which is almost always in the valve mechanism inside the tap body itself.

Where PTFE does come in during tap repair is when you are fitting new packing gland material around the spindle of an older pillar tap, to stop water weeping from the top of the tap rather than the spout. But this is a different fault, a different location, and a different fix. Knowing which type of leak you are dealing with is the first step - and this is where a quick diagnostic with the Voltrade GoFIX tool makes the difference between a 15-minute repair and an afternoon of trial and error.

Myth: DIY Tap Repair Is Always Cheaper Than Calling a Plumber

The Reality

Sometimes it is. A simple washer replacement on a traditional pillar tap is well within the capabilities of a careful homeowner with basic tools. A bag of assorted washers costs a few pounds. If that is the fault, and if you can isolate the water supply cleanly before starting, there is nothing wrong with having a go.

The myth falls apart when the repair is more complicated than expected - which, in our experience across East Sussex, is more often than not.

Here are common ways a DIY tap repair becomes expensive:

• The isolation valve under the sink has not been turned in years and seizes when you try to use it, causing a flood before work even begins
• You buy the wrong cartridge because you have misidentified the tap model, then buy another, then give up and call a plumber anyway who has to undo what you have done
• Old tap bodies on period properties in Eastbourne are often corroded and brittle - attempting to remove a seized gland nut without the right tools and technique can shear it off entirely
• The valve seat is scored and now needs professional regrinding, or the tap body needs replacing altogether

A plumber who gets it right first time typically costs between 80 and 150 pounds for a tap repair including parts. A DIY repair that goes wrong and then requires a plumber can cost 200 to 300 pounds or more, particularly if there is any water damage involved. The maths on saving money by doing it yourself depends heavily on correctly diagnosing the actual fault before you start.

Myth: A Slow Drip Is Nothing to Worry About

The Reality

A dripping tap producing one drop per second wastes approximately 15,000 litres of water per year. At current water rates in the South East, that commonly works out to an additional 30 to 60 pounds per year on a metered water bill, depending on your tariff. Many homes in East Sussex are on metered water supplies, meaning every litre counts directly towards your quarterly statement. Southern Water serves the majority of the Eastbourne area, and homeowners on meters will often see a slow drip reflected in their bills without connecting the two.

A dripping tap with a worn valve seat or damaged cartridge tends to get worse over time rather than staying the same. What starts as a slow drip after the tap is turned off commonly becomes a steady trickle, then a flow that cannot be fully stopped. Catching it early is cheaper than waiting.

There is also the secondary damage to consider. A slow drip into a sink or basin is not causing immediate harm, but a weeping tap connection inside a kitchen unit or vanity cupboard can saturate chipboard cabinetry over months - damage that costs hundreds of pounds to repair and is entirely avoidable. Our engineers regularly attend Eastbourne properties where a minor tap fault has been left for a year and the cabinet below needs replacing alongside the tap repair.

What Actually Matters - Expert Advice on Tap Repairs

Before touching anything, identify your tap type. This determines everything that follows - which parts you need, which tools are required, and whether the job is realistically DIY territory.

Here is how our engineers approach a leaking tap diagnosis:

1. Identify the leak location first. Is water dripping from the spout? Weeping from around the handle or base? Dripping from under the sink at the connection point? Each is a different fault with a different fix.
2. Identify the tap type. Quarter-turn ceramic disc, traditional rising spindle, cartridge mixer - look at how far the handle turns and whether the spindle rises visibly when you open it.
3. Check the water pressure. Unusually high water pressure (above 3 bar) accelerates wear on ceramic discs and can cause cartridges to fail repeatedly. A pressure-reducing valve may be the actual long-term solution rather than continuous cartridge replacement.
4. Turn off the water correctly. Use the isolation valve under the sink if there is one. If not, you will need to shut off the supply at the mains stopcock - in most Eastbourne properties this is under the kitchen sink or in a meter box near the front boundary.
5. Note the tap manufacturer and model before ordering parts. Cartridges from different manufacturers are not interchangeable. Take the old one to a plumber's merchant rather than a DIY superstore - they will match it correctly.

Water hardness is worth highlighting here. East Sussex sits in a hard water zone, and limescale build-up inside tap bodies and around cartridges is a significant cause of leaks across the region. Regular use of a proprietary limescale remover around tap heads and connections reduces wear on internal components and extends the life of a repair considerably.

Myth-Busting Questions About Tap Repairs

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

Repair makes sense if the tap body itself is in good condition - no cracks, no heavy corrosion, no stripped threads. Even an older tap can run well for many more years with a new cartridge or washer. Replacement becomes the better option when the tap body is damaged, when the style is outdated and parts are no longer available, or when repair costs approach the price of a decent new tap. A mid-range replacement mixer tap commonly costs between 60 and 150 pounds for the tap itself plus fitting labour, so it is worth doing the comparison before committing to a repair on a tap that is already on its last legs.

Can I repair a tap without turning off the mains water supply?

Only if there is a working isolation valve on the supply pipe directly below the tap - the small flat-headed valve that you turn 90 degrees to close. Always check it actually stops the flow before starting work, because isolation valves can fail or only partially close after years without use. If there is no isolation valve or it does not hold, you need the mains off before you touch anything. Attempting a tap repair with water under pressure is how floods happen. Our engineers test isolation valve function as a first step on every job, and it is a step worth taking seriously.

Why does my tap drip only at certain times of day?

This is typically a pressure issue. Water pressure in the mains supply fluctuates throughout the day - it is commonly higher at night when demand across the network drops, which is why many homeowners notice dripping taps after midnight or in the early hours. A worn cartridge or valve seat that holds at normal pressure will let water through when pressure spikes. The Voltrade GoFIX diagnostic process includes a pressure check for this exact reason. Fixing the worn component resolves the drip, but if pressure is consistently running high, a pressure-reducing valve installed on the incoming supply protects all the tap fittings across the whole property.

Frequently Asked Questions

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

A standard leaking tap repair by a plumber in Eastbourne typically costs between 80 and 150 pounds including labour and basic parts such as a cartridge or washer set. If additional work is needed - such as valve seat regrinding, replacing a seized isolation valve, or fitting an entirely new tap body - costs commonly run between 150 and 300 pounds. Always ask for an itemised quote before work starts so you know exactly what is included and can compare it against the cost of a full tap replacement.

Why does my tap drip after I turn it off?

A tap that drips after being turned off almost always has a worn or damaged sealing component inside - either a rubber washer that no longer creates a proper seal against the valve seat, or ceramic discs that have become chipped, scored, or coated with limescale deposits. In some cases on older taps the valve seat itself is damaged. The fault is inside the tap mechanism rather than in the pipes or water supply, and in most cases it is repairable without replacing the whole tap unit.

Is a leaking tap classed as an emergency plumbing job?

A tap dripping from the spout is not typically a plumbing emergency - it is an urgent repair, but the water damage risk is low if the water is draining normally. However, a tap that cannot be fully shut off, a leak from a connection underneath the sink, or water appearing inside a cabinet does warrant immediate action. Turn off the isolation valve or mains supply and call a plumber promptly. Most East Sussex plumbers offer same-day attendance for active leaks, typically at a higher call-out rate than a standard appointment booking.
