Leaking Tap Repair in Washington - A Complete Guide for Homeowners

Published September 2026 | Leaking Tap Repair Guide

The dripping starts quietly enough - a kitchen tap that wasn't quite closed off properly, or so you assume. Three days later it's still going, even with the handle cranked down as firmly as it'll go. That steady drip isn't just irritating; it's wasting water and adding needlessly to your bills, and it's not going to fix itself.

Understanding the Problem - What's Actually Going On Inside Your Tap

A leaking tap is a sign that one or more internal components have worn to the point where they can no longer create a watertight seal. Water is under constant pressure inside your pipes - typically between 1 and 3 bar in most UK homes - and the only thing stopping it from flowing out of a closed tap is a rubber washer, ceramic disc, or cartridge pressed firmly against a valve seat. When any of those components degrade, water finds its way through.

The location of the drip matters. A tap dripping from the spout usually points to a worn washer or damaged cartridge inside the body of the tap. Water seeping from around the base of the handle is a different problem - typically a failing O-ring or packing nut that seals the stem. Some taps leak from both points at once, which usually means the tap has simply reached the end of its serviceable life.

In Washington and across Tyne and Wear, the water supply is managed by Northumbrian Water. The water here sits on the softer side compared to many areas in the South, which is good news for taps - limescale build-up is less aggressive than in hard water regions. That said, taps still wear out, seals still harden and crack over time, and ageing pipework can create its own complications on top of that.

The Most Common Causes of a Leaking Tap

Understanding what's causing the leak helps you decide whether this is something you can tackle yourself or a job that needs a qualified plumber. Our engineers see the same handful of causes come up again and again in Washington homes.

Worn or Perished Rubber Washers

This is by far the most common culprit in older taps, particularly traditional pillar taps on kitchen sinks or older bathroom basins. Every time you turn a tap on or off, the rubber washer gets pressed hard against the valve seat. Over years of use - commonly 10 to 15 years under moderate use - the rubber hardens, cracks, or deforms and can no longer make a proper seal. The result is a constant drip from the spout even when the tap is fully closed.

The good news is that washers are cheap - usually just a few pence each from any plumbing merchant. The labour involved in getting to them is what you're paying for, not the part itself.

Damaged Ceramic Disc Cartridges

Modern taps, particularly quarter-turn lever taps, use ceramic disc cartridges rather than rubber washers. These are more durable than rubber, but they're not immune to failure. Grit or debris in the water supply can score the ceramic surface, and prolonged use eventually causes wear. A cracked or deteriorated ceramic cartridge will cause the tap to drip, and unlike a washer you can't repair the cartridge - you replace the whole unit.

Cartridges vary considerably in price depending on the manufacturer. Generic cartridges can cost as little as 5 to 15 pounds, but branded cartridges for taps from manufacturers like Grohe, Hansgrohe, or Bristan can run to 30 to 60 pounds or more. Getting the right replacement is important - a near-match rarely works as well as the correct part.

Worn O-rings

If the leak is coming from around the base of the tap handle rather than the spout, the likely cause is a worn O-ring. These small rubber rings create a seal around the tap's spindle or stem. When they wear or perish, water seeps out around the handle - you'll often notice damp patches on the worktop or basin surround rather than an obvious drip from the nozzle. O-rings are inexpensive, but getting to them on some modern taps requires partially dismantling the tap head, which can be fiddly if you haven't done it before.

Corroded or Pitted Valve Seats

The valve seat is the surface inside the tap body that the washer presses against to form a seal. In older Washington properties with ageing pipework, sediment and mineral deposits can corrode or pit this surface over time. Even a brand new washer won't seal properly against a damaged seat. This is where a simple washer job can become a more involved repair - the seat either needs to be reground using a tap reseating tool, or the tap body itself needs to be replaced.

Loose Packing Nuts

In older pillar taps, a packing nut holds the gland packing in place. This packing - sometimes a graphite-impregnated cord or a rubber gasket - compresses around the spindle to prevent water tracking up the stem. If the packing nut works loose or the packing material hardens with age, you'll get a slow seep of water around the spindle. Tightening the packing nut is often enough to stop this type of leak without any further disassembly.

Solutions That Actually Work

How you fix a leaking tap depends on the type of tap, the cause of the leak, and your own confidence with basic plumbing. Here's a practical breakdown of what each repair actually involves.

Before you do anything else, locate your stopcock. In most Washington homes this is under the kitchen sink or in a utility cupboard near the front of the house. You'll need to close this off before working on any tap. If you're not sure whether it fully isolates the supply, have towels and a bucket ready before you start.

For a traditional pillar tap with a dripping spout, the process typically runs like this:

1. Turn off the water at the stopcock and open the tap fully to drain any remaining pressure from the pipe.
2. Remove the tap handle by undoing a small screw, usually hidden under a decorative cap on top of the handle.
3. Use an adjustable spanner to unscrew the headgear (the internal mechanism) from the tap body - turn anti-clockwise.
4. At the base of the headgear you'll find the jumper and washer. The washer is held in place by a small nut or pressed into a recess.
5. Replace the washer with a matching size - 12mm or 3/4 inch are the most common for UK taps.
6. Reassemble in reverse order, turn the water back on slowly, and check carefully for any leaks before leaving the tap in use.

For quarter-turn ceramic disc taps, the process is similar up to the point where you remove the headgear - instead of a washer, you'll find the cartridge. Note the manufacturer's name on the tap if you can, since getting the right replacement cartridge matters. Take the old cartridge to a plumbing merchant or photograph it clearly before ordering a replacement online.

Fixing a leak around the base of the handle typically means replacing O-rings. These are available in assorted packs from any plumbing merchant or hardware shop for a few pounds. The challenge is matching the right size, so take the old ring with you when buying a replacement rather than guessing.

If you discover a pitted valve seat once the tap is dismantled, a tap reseating tool can grind the surface smooth again. These tools cost around 15 to 30 pounds and are available from larger hardware stores. It's a manageable job but requires patience and a steady hand to achieve an even finish.

When You Need a Professional and When You Can Sort It Yourself

Many tap repairs are within reach of a careful homeowner with basic tools and a bit of research. But there are situations where calling a plumber is the right call, and recognising those situations saves you from turning a minor problem into a significantly more expensive one.

You can likely handle it yourself if:

• The tap is a standard pillar tap or a common lever tap from a recognisable brand
• You can isolate the water supply easily and the stopcock turns and closes fully
• The fix involves a washer, cartridge, or O-ring replacement and the tap body looks in reasonable condition
• You're comfortable with basic spanner work and patient enough to do the job properly

You should call a plumber if:

• Your stopcock is seized or doesn't fully close - this is a problem in its own right and not something to work around
• The tap body or spindle is visibly corroded, cracked, or damaged
• You've already replaced the washer but the tap is still dripping - the valve seat is likely damaged
• The leak is coming from the pipework connections beneath the sink rather than from the tap itself
• You have a mixer tap with a complex cartridge system and you can't identify the manufacturer or source a replacement part
• The tap serves your boiler, hot water cylinder, or any gas appliance

In Washington and across Tyne and Wear, our engineers use the Voltrade GoFIX diagnostic tool to assess tap problems accurately before any work starts. That means you get a clear picture of what the repair involves and what it's likely to cost before we touch anything - no surprises on the invoice.

What to Expect from a Tap Repair Visit

If you've decided to bring in a plumber, knowing what the visit involves helps you prepare and avoids unexpected additions to the bill.

A competent plumber will start by isolating the water supply and inspecting the tap to confirm the cause of the leak before dismantling anything. This step matters because the fix for a worn washer and the fix for a corroded valve seat look identical from the outside but involve different work and different costs.

For a simple washer or cartridge replacement in Washington, you'd typically expect to pay somewhere between 60 and 120 pounds including parts, depending on the engineer's call-out rate and the cost of any specific cartridge required. If the valve seat needs regrinding or the tap needs to be replaced entirely, costs typically run between 120 and 250 pounds, with tap replacement costs varying depending on whether you supply your own tap or the plumber sources one for you.

A thorough plumber will also check the condition of your isolation valves - the small inline valves directly beneath the tap under the sink or basin - while they're there. These are commonly in poor condition in older properties and are worth addressing at the same time if they're not working correctly, since a seized isolation valve makes any future tap work much harder.

Most simple tap repairs can be completed within an hour to an hour and a half. If parts need to be ordered in - which occasionally happens with less common branded cartridges - a second visit may be needed, though most plumbers working in Washington carry a stock of common washers, O-rings, and standard cartridges.

Always ask for a fixed price or a clear breakdown before work starts. Any reputable plumber working in Tyne and Wear will provide this without hesitation, and it protects both you and them.

Common Questions from Washington Homeowners

How much water does a dripping tap actually waste?

A tap dripping at a rate of roughly one drop per second can lose around 15 to 20 litres of water per day - that's well over 5,000 litres across a full year from a single tap. If you're on a water meter, as many Washington households now are, that waste is directly reflected in your bills. Even on a rateable value charge, a persistent drip causes ongoing wear to the tap's internal components, so fixing it sooner is always better value than leaving it.

Can I use PTFE tape to stop a leaking tap?

PTFE tape is useful for sealing threaded pipe joints, but it won't fix a tap that's dripping from the spout or leaking around the handle. Those leaks are caused by worn internal components, not by threaded connections. Wrapping PTFE tape around tap threads can actually create more problems than it solves if applied in the wrong place, so use it only where it's genuinely appropriate - on compression fittings and threaded connections in pipework, not as a patch for a failing seal inside the tap body.

My landlord says it's my responsibility to fix the leaking tap - is that right?

In most cases, no. Under UK tenancy law, landlords are generally responsible for maintaining plumbing fixtures, including taps, in proper working order. Routine wear and tear - which covers worn washers, seals, and cartridges - typically falls on the landlord, not the tenant. If you caused damage to the tap yourself, that's a different matter. If your landlord in Washington is pushing back on this, raise it in writing and refer to your tenancy agreement alongside the Landlord and Tenant Act 1985.

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

It depends on the tap's condition and age. If the tap body is sound and the problem is a worn washer or cartridge, a repair makes good sense and will typically cost considerably less than a full replacement. If the tap is more than 20 to 25 years old, shows visible corrosion, or has needed repeated repairs over the years, replacement usually offers better long-term value. A new tap fitted by a plumber in Washington typically costs between 100 and 250 pounds all in, depending on the tap you choose and whether any additional pipework adjustments are needed.
