A dripping tap is more than just an annoyance—it can waste litres of water and increase your utility bills. Fortunately, fixing a leaking tap is a simple DIY task that usually involves replacing a worn-out washer or cartridge.
This guide provides step-by-step instructions to stop a dripping tap, whether it is a traditional or modern mixer tap.
1. Why Is Your Tap Dripping?
A leaking tap is often caused by:
- Worn-out washer – Common in traditional taps with rubber washers
- Faulty ceramic disc cartridge – Found in modern mixer taps
- Loose or damaged O-ring – A small rubber seal inside the tap
- Corroded valve seat – Where the washer seals the tap against water flow
2. Tools and Materials You Will Need
- Adjustable spanner (or wrench)
- Flathead and Phillips screwdriver
- Replacement washer or ceramic disc cartridge (depending on your tap)
- O-ring (optional)
- PTFE (plumber’s tape) for extra sealing
Tip: Take your old washer or cartridge to a DIY store like B&Q, Screwfix, or Wickes to find an exact replacement.
3. How to Fix a Dripping Tap (Step-by-Step)
Step 1: Turn Off the Water Supply
- Locate your home’s stopcock (usually under the sink).
- Turn it clockwise to shut off the water.
- Open the tap to drain any remaining water.
Step 2: Remove the Tap Handle
For Traditional Taps:
- Pry off the decorative cap (marked H or C for hot or cold) using a flathead screwdriver.
- Unscrew the handle and remove it.
For Mixer Taps (Ceramic Disc):
- Find the small screw under the handle (often hidden).
- Unscrew and pull the handle off gently.
Step 3: Replace the Washer or Cartridge
If It Is a Traditional Tap (Rubber Washer):
- Unscrew the tap body using a spanner.
- Remove the old washer from the valve and replace it with a new one.
If It Is a Mixer Tap (Ceramic Disc Cartridge):
- Remove the valve unit and take out the old ceramic disc cartridge.
- Insert the new cartridge and secure it properly.
For O-Ring Issues:
- Slide off the old O-ring and replace it.
Step 4: Reassemble and Test the Tap
- Reattach the tap components in reverse order.
- Turn the water supply back on.
- Test the tap—if the leak stops, your fix is successful.
4. When to Call a Plumber
While most dripping taps are easy to fix, call a plumber if:
- The tap still leaks after replacing the washer or cartridge
- The tap will not turn off fully
- The leak is coming from the pipework, not the tap
Cost: A professional tap repair in the UK costs between £50 and £100, depending on the complexity.
