Why does your tap need a repair kit?
A dripping tap wastes water and can damage your sink or vanity over time. Most modern taps use a ceramic disc cartridge that can wear out or get blocked by grit. Older taps use rubber washers that degrade. A tap repair kit under £100 gives you the right replacement parts without replacing the entire tap.
What to check before buying a tap repair kit
Tap type: Identify if your tap is a mono mixer, pillar tap, or kitchen mixer. Mono mixers typically need a cartridge. Pillar taps usually need a washer or valve.
Valve size: Most UK taps use 1/2 inch or 3/4 inch threads. Measure the diameter of your existing valve or cartridge.
Spline count: For mixer taps, the number of splines on the cartridge stem matters. Common counts are 12, 18, or 24 splines.
Ceramic vs washer: Ceramic disc cartridges last longer and provide smoother operation. Washer kits are cheaper but need replacing more often.
Mistakes to avoid
Buying a universal kit without checking compatibility. Many kits claim to fit all taps but do not fit every brand. Always remove your old cartridge first and compare dimensions.
Forgetting to turn off the water supply. Always isolate the hot and cold feeds before removing the tap handle.

FAQs
What is the difference between a ceramic disc cartridge and a washer cartridge?
A ceramic disc cartridge uses two smooth ceramic plates that slide against each other to control water flow, lasting longer and requiring less effort to turn. A washer cartridge uses a rubber washer that presses against a seat, which wears out faster and needs more turns.
How do I know which tap repair kit to buy?
Remove the tap handle and take out the old cartridge or valve. Measure its diameter, length, and count the splines on the stem. Compare these measurements to the specifications of the replacement kit.
Can I use a universal tap repair kit on any tap?
Universal kits work on many standard taps, but they may not fit every brand or model. Always check compatibility by comparing the old part to the new one before installation.
Do I need special tools to replace a tap cartridge?
Most tap cartridge replacements require only a screwdriver and an adjustable spanner. Some kits include a fitting tool, but basic tools are usually sufficient.
How long does a ceramic disc tap cartridge last?
Ceramic disc cartridges typically last 5 to 10 years, depending on water quality and frequency of use. Hard water can reduce their lifespan due to limescale buildup.
What causes a tap to drip after replacing the cartridge?
A drip after replacement usually means the cartridge is not the correct size, the splines do not match, or the tap seat is damaged. Check the fit and consider a reseating kit if needed.
Is it cheaper to repair a tap or replace it?
Repairing a tap with a kit under £100 is almost always cheaper than replacing the entire tap, which can cost £50 to £200 or more. Repair is also faster and less disruptive.
Can I fix a leaking mixer tap without a cartridge?
Some mixer tap leaks are caused by loose connections or worn O-rings, which can be fixed without replacing the cartridge. Check for visible damage or looseness before buying a new cartridge.
What is a tap reseating tool used for?
A tap reseating tool smooths the metal seat inside the tap body where the washer seals. It fixes leaks caused by a rough or pitted seat that prevents a proper seal.
Do all tap repair kits work with both hot and cold water?
Yes, most tap repair kits are designed for both hot and cold water supplies. The materials used, such as ceramic or brass, can handle typical household water temperatures.
How do I stop a tap from leaking at the base?
A leak at the base of a tap is usually caused by a worn O-ring or seal. Replacing the O-ring with a kit that includes various sizes can fix this issue.
Can I use a tap repair kit on a kitchen spray tap?
Kitchen spray taps often use a different cartridge design. Check the manufacturer's specifications or remove the old cartridge to find a compatible replacement.
