A dripping tap might seem like a small inconvenience, but over time it can waste a large amount of water and increase household costs. It may also be a sign that parts inside the tap have worn down.
Across Edinburgh, the relatively soft water supply means less limescale than in many parts of the UK, but taps still wear with everyday use. Many leaks can be repaired quickly using simple tools.
Why Taps Leak
Dripping taps usually occur because internal components become worn.
Worn washers
Traditional compression taps use rubber washers to seal the water flow. These gradually wear out and allow water to pass through.
Damaged O-rings
O-rings create a seal around the spindle or base of the tap. When they deteriorate, water can leak around the handle.
Faulty cartridges or ceramic discs
Modern mixer taps often use ceramic cartridges which can become damaged or blocked.
Loose components
Sometimes the issue is simply a loose internal part or gland nut.
Corroded valve seat
A damaged valve seat prevents the washer from sealing correctly.
Tools and Preparation
Before beginning the repair, collect the following:
- Adjustable spanner
• Screwdrivers
• Replacement washer or cartridge
• PTFE plumber’s tape
• Cloth to protect surfaces
Make sure the water supply is switched off first.
How to Fix a Leaking Tap
- Turn off the water supply
- Remove the tap handle
- Unscrew the bonnet to access the mechanism
- Remove the cartridge or valve
- Replace worn parts
- Reassemble the tap and test
Replacing the washer or cartridge often stops the leak.
When to Call a Plumber
If the leak continues after replacing parts, the issue may involve corrosion or valve seat damage.
