Leaking Tap Repair in Worthing - What Most Homeowners Get Wrong

Published October 2026 | Leaking Tap Repair

Most people think a dripping tap is a minor irritation they can deal with whenever they get around to it. They're wrong. That slow, rhythmic drip is wasting water, damaging your property, and getting worse every day - and most of the advice floating around about how to fix it is built on myths that lead homeowners to make the problem significantly more expensive.

Myth: A Dripping Tap Is Just a Minor Inconvenience

The Reality

A single tap dripping once per second wastes roughly 5,500 litres of water per year. For homeowners in Worthing on metered supplies, that typically translates to somewhere between 20 and 60 pounds disappearing down the drain annually - just from one tap. That's before you factor in the damage happening out of sight.

Water is patient and relentless. The drips that fall inside a sink cabinet, behind a wall, or onto grouting will find every small weakness in the surrounding materials. Our engineers regularly attend jobs in Worthing where what should have been a quick repair has turned into a full cabinet replacement because moisture got into the MDF beneath the sink over several months. Mould growth, timber rot, and tile adhesion failure are all common downstream consequences of leaving a dripping tap unattended.

What makes this myth so stubborn is that a dripping tap rarely feels urgent. Nothing floods. Nothing stops working entirely. The damage accumulates slowly out of sight, which is exactly the kind of damage that costs the most to put right - because by the time you notice it, it's already significant.

There's also the progressive wear to consider. A tap that drips twice per second today won't suddenly self-correct. Worn seals, corroded valve seats, and fatigued cartridges deteriorate under continuous water pressure. The drip you're ignoring now is almost certainly going to be a heavier drip in six months.

Myth: Turning the Tap Off Harder Will Stop the Drip

The Reality

This is one of the most damaging habits homeowners develop, and it's almost entirely counterproductive. The logic feels sound - if the tap is leaking, force it closed harder. But the mechanism causing the drip means extra force makes things worse, not better.

In traditional pillar taps, the seal is formed by a rubber washer pressing against a machined metal seat inside the tap body. Forcing the tap closed compresses and distorts the washer faster, accelerating the wear on the very component causing the problem. Repeated overtightening can also score and pit the metal seat itself. A damaged seat means even a brand-new washer won't seal properly - the rubber presses against an uneven surface and the drip returns within weeks.

In modern mixer taps - which are far more common in UK homes now and use ceramic disc cartridges rather than rubber washers - the consequences of overtightening are more acute. Ceramic is hard and durable under normal operating conditions, but brittle under sudden concentrated pressure. Forcing a ceramic tap closed hard can crack the discs inside the cartridge. A cracked ceramic cartridge needs replacing entirely, typically at a parts cost of 15 to 40 pounds, plus labour. If the cartridge housing is also damaged in the process, you could be looking at a full tap replacement costing between 80 and 250 pounds depending on the style and brand.

The tap temporarily stops dripping after you lean on it hard because you've forced a compromised washer or cartridge to temporarily plug the gap. The underlying wear hasn't changed at all. Within hours, sometimes minutes, it starts again.

Myth: Every Leaking Tap Just Needs a New Washer

The Reality

Washers are the best-known tap component, so they take the blame for almost everything. But a significant proportion of taps in UK homes don't use rubber washers at all - and fitting a new washer to a tap that uses ceramic cartridges won't help, because there's no washer in there to replace.

Traditional separate hot and cold pillar taps use rubber washers. Most modern taps - including monobloc mixer taps, thermostatic bar mixers, and single-lever kitchen taps - use ceramic disc cartridges, O-rings, or a combination of both. Opening one of these taps expecting to find a washer means you won't find what you're looking for, and you'll have disassembled the tap for nothing.

Even on taps that do use washers, the washer often isn't the root cause. The tap seat - the machined metal surface the washer presses against - can corrode, scale up, or become pitted over time. Pressing a brand-new rubber washer against a damaged seat means the washer fails again within a few weeks. The correct repair is to re-grind the seat using a tap reseating tool, or replace the seat insert if the tap design allows it.

Our engineers use the Voltrade GoFIX diagnostic approach before starting any tap repair. Checking the tap type, identifying whether the fault is at the seat, the washer, the cartridge, or an O-ring, takes a few minutes but prevents the common mistake of replacing the wrong component and having the homeowner call us back a fortnight later.

The main fault types our team encounters on leaking taps:

1. Worn rubber washer (traditional hot and cold pillar taps)
2. Damaged or worn ceramic disc cartridge (modern mixer taps and monoblocs)
3. Failed O-ring around the spout body (causes leaking at the base rather than from the spout)
4. Pitted or corroded tap seat (washer keeps failing quickly after replacement)
5. Scale-blocked or cracked cartridge housing (more common in harder water areas)

Getting the diagnosis right is what determines whether a repair holds for years or starts dripping again within the month.

Myth: Fixing a Leaking Tap Is Always a Simple DIY Job

The Reality

Some tap repairs are within reach for a competent DIYer with basic tools. Replacing a washer in a traditional pillar tap, where the water isolates cleanly and the mechanism is accessible, is something many homeowners can manage. But that's a narrow set of circumstances, and things get complicated fast.

A significant number of properties in Worthing and across West Sussex - particularly older terraced houses and purpose-built flats - have isolator valves on their supply pipes that haven't been turned in a decade or more. These valves can seize, fail to close fully, or begin leaking themselves when operated for the first time in years. If an isolator valve fails mid-repair, you've lost running water to part of the property until the main stopcock can be used. If the main stopcock is also corroded or stuck - which is common in older properties - you now have a situation requiring an emergency plumber, not a washer swap.

Parts compatibility is another common sticking point. Ceramic tap cartridges vary considerably in diameter, depth, and valve orientation. Ordering a cartridge that looks similar but doesn't match your tap's exact specification means it either won't fit, will fit but leak because the tolerances are wrong, or the tap handle will turn the wrong direction. For branded taps, you need the specific model number to order correctly, and that information isn't always obvious from looking at the tap.

There's also the question of what you discover when you open things up. Corroded compression fittings, failing flexible tap connectors, and deteriorating pipework are common findings during what looks like a quick job. A professional can deal with these on the spot. A DIYer who discovers corroded connections halfway through a repair is in a difficult position - work half-done, water turned off, and a problem they weren't equipped to handle.

For a professional tap repair in the Worthing area, expect to pay typically between 60 and 150 pounds including call-out, depending on the complexity of the fault and the parts required. Set against the cost of a repair that goes wrong, causes water damage, or requires a second emergency call-out, that's a reasonable cost for a reliable result.

Myth: New Taps Don't Develop Faults This Soon After Installation

The Reality

It's a common assumption that a recently fitted tap shouldn't need any attention for several years. In practice, leaks in newer taps are often caused not by the tap wearing out, but by how it was installed in the first place.

Cartridges not seated squarely, O-rings pinched or rolled during fitting, and inlet connections overtightened to the point of cracking are all installation errors that cause leaks to appear in the weeks or months after a tap goes in. These faults can be subtle - a slightly misaligned cartridge will seal under low pressure but weep under normal household mains pressure. Our engineers see installation-related faults on relatively new taps across West Sussex more regularly than most homeowners would expect.

Manufacturer defects also occur at all price points. Ceramic disc cartridges can be faulty from the box. If your tap is under 12 months old and already dripping, check the manufacturer warranty before spending money on a repair. Most reputable tap brands offer at least a one-year parts warranty, and some cover five years or more.

Water quality is another factor that's frequently overlooked. Parts of West Sussex sit in moderate to hard water zones, and limescale deposits form inside tap mechanisms faster than most people realise. A 12-month-old tap in a hard water area can already have meaningful scale buildup inside the cartridge housing, which reduces how effectively the discs seal and leads to a drip that looks like early product failure but is actually a water chemistry issue. In these cases, treating the water rather than just the tap is the more durable solution.

What Actually Matters - Expert Advice on Getting a Tap Repair Right

The myths aside, here's what actually determines whether a leaking tap repair holds up long-term.

Identify the tap type before buying anything. Traditional separate hot and cold pillar taps use rubber washers. Monobloc mixers, thermostatic taps, and bar mixers use cartridges. Knowing this before you start means you're not buying parts you can't use.

Isolate the water properly. Most modern taps have isolator valves on the supply pipes beneath the sink - a flathead screwdriver slot on a small brass fitting. A quarter turn so the slot is perpendicular to the pipe means it's closed. If you don't have isolators, or they won't move, use the main stopcock rather than trying to work around a valve that won't close fully.

Match parts precisely. Tap cartridges are not interchangeable between models even when they look similar. Take the old cartridge to a plumbing merchant to compare, or look up the specific tap model number before ordering online. A close-but-wrong cartridge means the leak continues, and you've wasted the cost of the part.

Don't overtighten when reassembling. Finger-tight plus a quarter turn with a spanner is sufficient for most tap fittings. Any more force than that risks cracking ceramic components, splitting plastic fittings, or distorting fibre washers. The instinct to tighten harder to "make sure" is almost always the wrong call.

Test properly before calling the job done. Turn the water back on slowly, run the tap for a minute, then turn it off and wait. Check the spout for drips, the base of the tap body for weeping, and the supply connections under the sink. A tap that looks fixed but has a slow seep at a connection underneath will cause water damage just as surely as the original drip - it just takes longer to show up.

Myth-Busting Questions

Can PTFE tape be used to stop a tap dripping from the spout?

PTFE tape is for sealing threaded connections - the joints where pipes meet tap bodies, isolator valves, or flexible connectors. It has no effect on the washer or cartridge mechanism that causes a tap to drip from the spout. Wrapping PTFE around internal components in an attempt to stop a drip won't work and can make the tap harder to disassemble correctly for a proper repair later. Use PTFE on threaded pipe connections only, wrapping clockwise with three to five turns.

Is a constantly dripping tap considered a plumbing emergency?

A tap dripping from the spout is not typically an emergency in the way a burst pipe is, but it shouldn't be ignored indefinitely. The risk escalates if the leak is at the base of the tap rather than from the spout, particularly if water is pooling inside a cabinet or running onto surfaces below. In those cases, getting a repair done within a day or two is sensible rather than waiting. A spout drip gives you more time, but every week of delay means more water wasted and more wear on the surrounding components.

Do all taps eventually need replacing rather than repairing?

Not at all. Most taps can be repaired multiple times over their lifespan by replacing washers, cartridges, and O-rings as each component wears. Replacement becomes the better option when the tap body itself is corroded, the threads are stripped, or manufacturer replacement parts are no longer available for an older model. A useful guide: if the total repair cost exceeds roughly half the price of a new equivalent tap fully fitted, replacement is usually the more economical long-term choice.

Frequently Asked Questions

How much does a leaking tap repair cost in Worthing?

Professional leaking tap repairs in Worthing typically cost between 60 and 150 pounds for a standard job, including call-out charge and parts. The lower end of that range covers a simple washer or cartridge replacement on a tap with accessible isolator valves. The upper end applies to more complex faults, seized valves, or taps requiring non-standard parts. Always ask for a clear quote before any work starts so there are no surprises on the final bill.

How long does a typical tap repair take?

Most tap repairs take between 30 minutes and two hours depending on the fault and the condition of the surrounding pipework. A basic washer or cartridge replacement on an accessible tap with functioning isolators sits at the shorter end of that range. Jobs involving seized valves, corroded connections, or sourcing specific cartridge parts for an older tap take longer. In the vast majority of cases, a single visit is enough to complete the repair fully without a return trip for additional parts.

Should I repair or replace a tap that is more than ten years old?

Age alone is not a strong reason to replace a tap that's otherwise in good condition. If the fault is a worn washer, failed cartridge, or deteriorated O-ring and the tap body itself is sound, repair is almost always better value. Consider replacing if the tap is visibly corroded, has been repaired several times and keeps developing new faults, or if replacement parts are no longer stocked by plumbing merchants for that model. A tap that's been well-maintained can last twenty years or more with periodic component replacement.
