How to Fix a Leaking Tap in Ramsgate - A Complete Repair Guide

Published August 2026 | Leaking Tap Repair Guide

This guide covers how to diagnose and repair a dripping or leaking tap in your home, from identifying the cause through to replacing the internal components yourself. It's aimed at Ramsgate homeowners who are comfortable with basic DIY and want to attempt the repair before booking a plumber.

Before You Start - Safety First

Before you touch anything under the sink or behind a tap, you need to cut the water supply. This sounds obvious, but it's the step that causes the most grief when skipped. Water under mains pressure will make a mess of your kitchen or bathroom fast, so don't rush this part.

Most taps are fed by isolator valves located directly below the sink, usually on the hot and cold supply pipes. They look like small brass fittings with a flat-head screw slot. Turn the slot 90 degrees so it sits across the pipe rather than running along it - that means the valve is closed. If your property doesn't have isolator valves under the sink (common in older Ramsgate housing stock), you'll need to turn off the water at the main stopcock. This is typically found under the kitchen sink, in a cupboard under the stairs, or in the utility room. Turn it clockwise until it stops.

Once the supply is off, open the tap fully to release any residual pressure in the pipe and let the water drain away. Put an old towel in the sink and place a small bucket or tray under the pipework - there's almost always a bit of water sitting in the trap or supply lines.

One more thing: work in good light. Bathroom cabinets and under-sink spaces are dark. A decent head torch will save you a lot of frustration when you're trying to read the thread direction on a small brass nut.

What You Will Need

Getting your tools together before you start means you won't be halfway through a disassembled tap when you realise you're missing something critical.

Tools:

• Adjustable spanner (a 200mm and a 300mm if you have them)
• Crosshead and flathead screwdrivers
• Allen key set (many modern tap handles use a grub screw)
• Plumber's grease or silicone grease
• PTFE tape
• Head torch or work light
• Cloth or rag

Materials - and this is where it matters:

• Tap washer set (a mixed pack covers most sizes and costs around 3 to 5 pounds)
• O-ring kit (again, a mixed pack is worthwhile - typically 3 to 6 pounds)
• Replacement cartridge if you have a monobloc or ceramic disc tap (varies widely by brand - budget 8 to 25 pounds, more for premium brands)

Before buying parts, identify your tap type. Traditional pillar taps (separate hot and cold, with a round handle) almost always use a rubber washer. Monobloc mixer taps - the single-lever type found in most modern kitchens - typically use a ceramic cartridge. Quarter-turn taps with ceramic disc internals will need a ceramic disc replacement rather than a rubber washer. If you're in any doubt, take a photo of the tap and the removed components into your local plumber's merchant. There are good trade suppliers in Kent who'll point you in the right direction.

Time estimate: Allow 30 to 60 minutes for a standard washer replacement. A cartridge swap on a monobloc tap can take 45 to 90 minutes if you haven't done it before, especially if the tap is older and components are corroded in place.

Step-by-Step Instructions

Step 1 - Isolate the water supply and prep the workspace

Close the isolator valves under the sink by turning the screw slot 90 degrees, or shut off the main stopcock. Open the tap to release pressure and drain the lines. Lay your towel down and position your bucket. Double-check the water is off by trying the tap - only a trickle or nothing should come out.

Step 2 - Remove the tap handle

Most tap handles are secured by a grub screw hidden under a decorative cap on top of the handle. Prise this cap off carefully with a flathead screwdriver - they're usually just pressed or screwed on. Underneath you'll find either a Phillips head screw or a small hex bolt requiring an Allen key. Remove this fixing and lift the handle straight off. If it's stuck, don't force it sideways - a gentle rocking motion while pulling upward usually frees it. Penetrating oil left for a few minutes helps on older taps that haven't been touched in years.

Step 3 - Remove the headgear or cartridge

With the handle off, you'll see the headgear (on a traditional tap) or the cartridge assembly (on a monobloc). The headgear is a large brass nut that screws into the tap body. Use your adjustable spanner to turn it anti-clockwise and unscrew it. Be firm but controlled - the tap body needs to stay still while you turn the nut, so use your other hand or a second spanner to hold the tap base if it moves.

On a monobloc tap, the cartridge is usually held in by a retaining nut or clip. Remove this and pull the cartridge straight out. Note which way it's oriented before removal - photograph it if you need to.

Step 4 - Replace the washer or O-ring

At the base of the headgear you'll see a rubber washer, typically held in place by a small brass nut. Unscrew this nut, remove the old washer, and fit the new one of the same diameter. Give the seat inside the tap body a quick inspection with a torch - if it looks scored or damaged, no new washer will hold for long (more on this below).

If the leak is coming from the base of the spout rather than the outlet, the likely culprit is an O-ring sitting around the body of the headgear. These are the rubber rings that sit in grooves on the headgear stem. Roll off the old O-ring and stretch the new one into place. Apply a thin smear of silicone grease to help it seat correctly and protect it from wear.

If you're replacing a ceramic cartridge, simply insert the new one in the correct orientation and reassemble. No washer or O-ring work is needed - the cartridge is a self-contained unit.

Step 5 - Reassemble the tap

Work in reverse order. Screw the headgear back in clockwise - hand-tight first, then snug with the spanner. Don't overtighten; you're sealing against a rubber washer, not metal on metal, and excess force can split the seat. If you applied PTFE tape to any threads (sometimes useful on older fittings with worn threads), wrap it clockwise so it doesn't unravel as you screw the nut in.

Refit the handle, tighten the retaining screw, and press the decorative cap back into place.

Step 6 - Restore the water supply and test

Turn the isolator valves back open slowly - a quarter turn back to align with the pipe. Let the pressure build for 30 seconds, then check under the sink for any drips from the supply connections. Now operate the tap and watch closely. Let it run for a minute, then turn it off and watch the outlet for 30 seconds. No dripping means the job is done. If it still drips, tighten the headgear by a quarter turn and test again before assuming the repair has failed.

Step 7 - Clean up and document

Note down what parts you used and keep any spares. If you're in a Ramsgate property with older plumbing - particularly pre-1990s housing - there's a reasonable chance you'll be back at this tap again in a year or two. Knowing the exact washer size saves time next time.

What to Do If This Does Not Fix It

If the tap is still dripping after a new washer or O-ring, the problem is likely a damaged valve seat inside the tap body. The seat is the machined surface the washer presses against to form a seal. Over time, hard water deposits, grit in the supply line, or simply age can score or pit this surface. A new washer pressed against a damaged seat will never seal properly.

A seat grinding tool - sometimes called a reseating tool - can be bought or hired and used to re-cut the seat back to a smooth surface. It's a fiddly job but entirely possible for a capable DIYer. Alternatively, a tap repair kit often includes a plastic seat insert that presses into the existing seat and gives the washer a clean surface to work against.

If the leak is from the base of the tap or around the spout joint rather than the outlet, it's more likely an O-ring issue rather than the seat. Go back and check all the O-ring positions carefully. The Voltrade GoFIX diagnostic tool can help you narrow down where the leak is originating from if you're not sure, which saves stripping the whole tap again unnecessarily.

For monobloc taps that continue leaking after cartridge replacement, check that the new cartridge is correctly orientated and that the retaining nut is fully tightened. A cartridge that's even slightly cocked in its housing will let water through.

When to Stop and Call a Professional

Some situations call for a qualified plumber, and recognising them early saves you from a bigger repair job later.

Call a plumber if:

• You can't isolate the water supply because isolator valves are seized or absent, and you don't know how to safely shut off the mains
• The tap body itself is cracked or corroded through - no repair will hold
• The supply pipes are plastic push-fit and one has pulled loose when you moved the tap
• There's water coming from behind the wall or under the floor - this is a separate leak and nothing to do with the tap
• The headgear nut shears or rounds off and won't move - forcing it further risks damaging the tap body beyond repair
• You have lead pipework (identifiable by its dull grey colour and soft, bendable quality) - this should be assessed by a professional and is common in parts of Ramsgate's older residential areas

A local Ramsgate plumber will typically charge between 60 and 120 pounds for a callout and basic tap repair, with parts on top. If the tap needs full replacement, budget 150 to 300 pounds including labour depending on tap type and access. Emergency or out-of-hours callouts in Kent will cost more - usually 150 pounds or above just to attend.

If you've got a leak you genuinely can't stop and can't reach a plumber immediately, close the main stopcock and leave the water off until you can get help. Running water onto a wet subfloor or into a cabinet overnight causes serious damage that costs far more to fix than the original leak.

Questions About This Process

How much does it typically cost to fix a dripping tap in Ramsgate?

If you do the repair yourself, parts cost very little - a washer kit runs 3 to 5 pounds and a replacement ceramic cartridge is usually 8 to 25 pounds depending on the tap brand. If you call a plumber in Ramsgate, expect to pay between 60 and 120 pounds for labour on a standard repair, plus parts. Emergency callouts or weekend appointments in Kent will push that figure higher, commonly 150 pounds or more.

How do I know if I have a ceramic disc tap or a traditional washer tap?

The simplest test is how the handle moves. Traditional washer taps require multiple turns - usually two or more full rotations - to go from fully closed to fully open. Ceramic disc taps operate with a quarter turn only, from fully off to fully on in 90 degrees of movement. Monobloc taps with a single lever are almost always ceramic cartridge. If you're still unsure, removing the handle and headgear will tell you immediately: rubber washer at the base means traditional, ceramic disc means the other type.

Can a dripping tap cause serious damage if I leave it?

Yes, over time it can. Beyond the water waste - a tap dripping once per second wastes roughly 30 litres a day - a persistent drip keeps moisture in the cabinet under your sink, encouraging mould growth and softening the cabinet base. It also causes limescale build-up on the seat and washer over time, which accelerates wear. In Ramsgate and across much of Kent, where water hardness is moderately high, scale deposits can significantly shorten the life of tap internals if a slow drip is left running for months.
