A dripping tap may appear harmless, but even a slow leak can waste thousands of litres of water each year and increase your household water costs. Left unresolved, it may also signal worn internal parts that could lead to leaks or damage around sinks and worktops.
Across Edinburgh, relatively soft water means taps experience less limescale than in harder water regions. However, everyday use still causes components to wear out. Fortunately, many dripping taps can be repaired quickly with a few simple tools.
Why Fix a Dripping Tap Quickly?
Ignoring a small drip can allow the problem to worsen. A damaged washer or faulty cartridge can easily turn a minor drip into a constant leak.
Persistent dripping may also indicate issues such as worn internal components or pressure irregularities within the plumbing system. Repairing the tap early helps reduce water waste and avoid more costly repairs later.
Common Causes of a Dripping Tap
Dripping taps are usually caused by worn internal components.
Worn washer
Older taps use rubber washers that eventually wear out, allowing water to pass through.
Faulty cartridge or ceramic disc
Modern mixer taps contain ceramic cartridges that may wear down or become blocked with debris.
Damaged O-ring
O-rings seal areas around the tap handle and base. When these deteriorate, leaks can appear around the tap body.
Loose or corroded components
Internal fittings may loosen or corrode over time, preventing a proper seal.
High water pressure
Excess pressure can push water through fittings and seals.
How to Fix a Dripping Tap
Many dripping taps can be repaired using basic tools.
- Turn off the water supply.
- Remove the tap handle and decorative cap.
- Access the tap mechanism.
- Remove the valve or cartridge with a spanner.
- Replace any worn washers, cartridges or O-rings.
- Reassemble the tap securely.
- Restore the water supply and test the tap.
Often, simply replacing a washer or cartridge will stop the drip.
When to Call a Plumber
If the leak continues after replacing parts, the issue could involve deeper problems such as corrosion or a worn valve seat.
Preventing Future Drips
- Avoid tightening taps too firmly
• Check taps periodically for early leaks
• Maintain balanced water pressure
• Use quality tap fixtures when replacing fittings
