Leaking Tap Repair in Norwich: Busting the Myths That Are Costing You Money

Published August 2026 | Leaking Tap Repair Guide

Most people think a dripping tap is no big deal - just background noise you tune out after a few days. That's one of the most expensive assumptions a homeowner can make. A leaking tap is rarely just a leaking tap, and the myths surrounding what causes them, how to fix them, and when to call a plumber are keeping people in Norwich paying more than they should.

The reality

A tap dripping once per second wastes roughly 5,500 litres of water per year. On a metered supply - which a significant proportion of Norfolk homes now have - that translates directly to a higher water bill, every single year the tap is left unrepaired. The irony is that the fix, in most cases, costs far less than the accumulated waste.

Our engineers see this regularly in Norwich homes: a kitchen tap that's been dripping for two or three years, owners assuming it's "not worth the bother." When we price up the water cost against a typical repair bill, the maths rarely stacks up in favour of waiting. Repair costs typically sit between 60 and 150 pounds for a straightforward washer or cartridge job. The water you're wasting in the meantime isn't free.

There's also the structural side. Water finding its way past a worn seal doesn't always drip neatly into the basin. It can work back through threads, around gland nuts, and into the cabinet below - causing timber swelling, mould, and eventually damage that costs a lot more to put right than a new washer ever would have.

The reality

Replacing the washer is the right fix for some taps - specifically older pillar taps with a rubber washer seated on a jumper valve. But it's not the universal solution people assume it to be. Modern taps use completely different internal mechanisms, and diagnosing a leak without understanding which type of tap you're dealing with is where a lot of DIY attempts go wrong.

There are four main tap types you're likely to encounter in Norwich homes:

Compression taps (the traditional style with rubber washers) - these do respond well to washer replacement, provided the valve seat isn't damaged.
Ceramic disc taps - these use two ceramic discs that rotate against each other. When they leak, you typically need to replace the ceramic cartridge, not a washer. Using a rubber washer here achieves nothing.
Ball taps - common on single-lever kitchen mixers, these have a rotating ball mechanism. Leaks usually involve worn O-rings or springs inside the ball assembly.
Cartridge taps - again common on mixer taps, these use a replaceable cartridge. The fix is swapping the cartridge, not applying a washer.

Our Voltrade GoFIX diagnostic approach starts with identifying the exact tap type before recommending any repair. Throwing the wrong fix at a ceramic disc tap can make the situation worse - cracked ceramics don't respond well to being forced.

The reality

This is one of the most damaging habits our engineers encounter. When a tap starts dripping, the instinct is to crank it shut as hard as possible. It might briefly stop the drip - or at least slow it - which feels like confirmation that the strategy works. It doesn't.

On compression taps, the rubber washer sits against a metal valve seat. Over-tightening grinds the washer into the seat, accelerating wear. You end up needing a new washer sooner, and if you've damaged the brass seat in the process, you're now looking at reseating the valve with a specialist tool or replacing the tap body entirely.

On ceramic disc taps, forcing the mechanism is even worse. Ceramic is hard but brittle. A cracked disc means the cartridge has to be replaced rather than simply serviced. Cartridges for quality taps - Bristan, Grohe, Hansgrohe - can cost anywhere from 15 to 60 pounds for the part alone, on top of labour.

If your tap is dripping, turn it off with normal hand pressure and book a repair. Don't try to muscle the problem away - it doesn't work and it shortens the life of the tap.

The reality

Replacing a tap is sometimes the right call - but it's far from always necessary, and it's a conclusion people often jump to prematurely. In most cases, what's failed is a small internal component: a rubber washer, a ceramic cartridge, an O-ring, or a gland packing nut. These are serviceable parts that cost a few pounds and take a skilled plumber under an hour to swap out.

Full tap replacement becomes the sensible option when:

1. The tap body itself is corroded or cracked
2. The valve seat is too damaged to reface
3. Replacement cartridges are discontinued and unavailable
4. The tap is very old and the owner wants to upgrade anyway

If your tap is a relatively modern model - say, less than 15 years old - the odds are good that a repair is viable and economical. Even for older taps, it's worth a diagnostic check before committing to a full replacement. A repair might cost 60 to 120 pounds including labour. A new tap installation, including supply and fitting, typically runs between 120 and 280 pounds depending on the tap chosen and the complexity of the installation.

We see both extremes in Norfolk properties - new-builds where a £12 cartridge has been overlooked for months, and Victorian terrace conversions in Norwich where the tap body genuinely is beyond economical repair. The distinction matters, and it starts with a proper look at what's actually going on.

The reality

These are two different failure points and they have different causes. A dripping spout - water coming out of the end of the tap when it's switched off - points to a failed washer, cartridge, or disc inside the body of the tap. A leak from the base of the tap, where it meets the sink or basin, is typically a problem with the O-rings on the tap stem or a degraded tap tail seal.

Base leaks are commonly misdiagnosed because they're less visible. The water pools in the cabinet underneath rather than dripping into the basin where you'd spot it immediately. By the time a homeowner notices a damp cabinet floor in their Norwich kitchen, the water has often been sitting there long enough to start softening the chipboard shelf below the sink.

The fix for a base leak usually involves isolating the supply, removing the tap, and replacing the O-rings or fibre washers on the tap tails. It's not a complicated job, but it does require isolating the water supply and knowing which seals to replace. Bodging a base leak with PTFE tape from the outside rarely holds for long - the pressure finds a way through eventually.

The reality

In theory, every tap should have an isolation valve on its supply pipes - usually tucked inside the cabinet below the sink, where you can use a flathead screwdriver to turn it 90 degrees and cut off flow to just that tap without affecting the rest of the house. In practice, a lot of homes - particularly older properties in Norfolk - either don't have proper isolation valves, or have valves that have seized through years of disuse.

Attempting to replace a washer without a working isolation valve means shutting off the main stopcock. You'll know where yours is, we hope - typically under the kitchen sink or where the service pipe enters the property. If you don't know, find out before you need it in a hurry.

What our engineers regularly find in older Norwich properties is that the stopcock itself is stiff, partially seized, or doesn't fully isolate the supply. This is not the moment to find that out. If you're attempting any tap repair as a DIY project, test your isolation valves and stopcock first. Turn them, make sure they work, make sure they actually stop the flow. If your stopcock is stiff or only partially closes, getting it serviced before it becomes an emergency is money well spent.

Across our Norwich and wider Norfolk callouts, the tap repairs that go smoothly tend to share the same characteristics: the right diagnosis, the right parts sourced in advance, and the water supply properly isolated before work begins. The ones that become complicated jobs almost always have at least one of those missing.

Here's what actually helps:

1. Identify your tap type before anything else. If you're not sure, a photo of the tap (and ideally of the inside mechanism if you can safely access it) goes a long way. Knowing whether you have compression, ceramic disc, cartridge, or ball-type is the foundation of the right repair.
2. Source parts before isolating the water. Once the water's off, you want to be reinstating it the same day. Running to a plumbers' merchant mid-job because the washer doesn't fit means a cold, waterless house while you're gone.
3. Check the valve seat on older compression taps. A new washer on a scored seat will leak again within months. Reseating the valve with a tap reseating tool costs a few pounds if you're doing it yourself, or takes a few minutes if your plumber does it.
4. Don't ignore slow leaks at the gland nut. A tap that weeps from the spindle area - not the spout, not the base, but from around the handle stem - usually needs the gland nut tightened or the packing replaced. It's a quick fix, but left alone it gets worse.
5. For mixer taps, check the hot and cold supplies separately. A mixer that drips might have one failed cartridge on the hot side, one perfectly fine on the cold. Replacing both when only one is at fault isn't wrong, but it's worth knowing which is the problem.

The Voltrade GoFIX diagnostic process runs through each of these checkpoints systematically before a repair is quoted. It means our engineers arrive with the right parts for the job, not a van full of possibles and a best guess.

Can I repair a leaking tap myself, or do I always need a plumber?

Replacing a rubber washer on an older-style pillar tap is genuinely within reach for a confident DIYer. You'll need to isolate the water supply, remove the headgear with an adjustable spanner, and swap the washer and O-ring. Where it gets more involved is ceramic disc taps, mixer taps with cartridge mechanisms, or any situation where the valve seat is damaged. If you're not confident identifying the tap type and have any doubt about isolating the supply safely, a plumber is the sensible call - the repair typically costs 60 to 120 pounds and takes under an hour.

Why does my tap still drip after I replaced the washer?

The most common reason is a damaged valve seat. Even a brand-new rubber washer can't create a watertight seal against a scored or pitted brass seat. The seat needs to be resurfaced with a tap reseating tool, or the tap body needs replacing. The second most common reason is that the wrong washer size was used - tap washers come in different diameters, typically 12mm or 15mm for standard taps. If you've swapped the washer and the drip continues, the seat is the next thing to check.

How much should a leaking tap repair cost in Norwich?

For a standard washer or cartridge replacement on a kitchen or bathroom tap, expect to pay in the region of 60 to 150 pounds including labour for a local Norwich plumber. That range moves depending on the tap type, parts required, and callout pricing for the time of day. Emergency evening or weekend callouts typically attract higher rates. Full tap replacement, where the tap itself needs swapping out, usually comes in between 120 and 280 pounds all in, depending on the tap specified and access difficulty. Always get the diagnosis confirmed before agreeing to a full replacement if a repair might be viable.

Frequently Asked Questions

Is a dripping tap in a Norwich rental property the landlord's responsibility to fix?

Yes, in most cases. Under the Landlord and Tenant Act 1985, landlords are responsible for maintaining water supply installations in a proper working order. A dripping tap caused by normal wear and tear - a worn washer, a failed cartridge - falls to the landlord to repair. Tenants should report the fault in writing and keep a record of the notification. If the leak worsens and causes damage while awaiting repair, that documentation matters. Tenant-caused damage is a different matter, but standard component failure is not a tenant liability.

How long does it typically take for a leaking tap to be repaired?

A standard washer or cartridge replacement on an accessible domestic tap typically takes between 30 and 60 minutes once a plumber is on site. The total time from booking to completion depends on availability, but for a non-emergency repair in Norwich, most local plumbers can attend within one to three working days. Emergency same-day callouts are usually available but cost more. If specialist parts need ordering - certain ceramic cartridges for less common tap brands, for example - allow an extra day or two for delivery before the repair can be completed.

Can a leaking tap increase my water bill in Norfolk?

Definitely. Norfolk homes on metered water supplies - and the majority now are - pay for every litre used. A tap dripping at a steady rate can add hundreds of litres to monthly usage without the homeowner noticing any obvious change in daily habits. If your bill has crept up without explanation, it's worth checking every tap, including outdoor taps and garden hoses, for slow leaks. The repair cost is almost always recovered in water savings within a few months, particularly on properties with higher metered rates.
