How to Fix a Leaky Tap: Step-by-Step Guide
A dripping tap is one of the most common household problems, wasting water and creating an annoying sound. The good news is that most tap leaks can be fixed with basic tools and minimal plumbing experience.
Before You Start
Tools You'll Need
- Adjustable spanner
- Screwdriver set
- Torch or headlamp
- Cloth or old towel
- Penetrating oil (if needed)
Safety First
Always turn off the water supply before starting any repair. Locate your stopcock (usually under the kitchen sink or by the front door) and turn it clockwise to shut off the water.
Diagnosing the Problem
Common Causes of Leaky Taps
- Worn washer: Most common in traditional taps
- Damaged O-ring: Causes leaks around the base
- Worn valve seat: In ceramic disc taps
- Corroded valve: In older taps
Step-by-Step Repair Guide
For Traditional Washer Taps
Step 1: Remove the Tap Handle
Look for a screw under a decorative cap on top of the handle. Remove the cap and unscrew to lift off the handle.
Step 2: Remove the Headgear
Use an adjustable spanner to unscrew the hexagonal headgear (packing nut). Turn anti-clockwise to remove.
Step 3: Replace the Washer
At the bottom of the headgear, you'll find a rubber washer held by a small screw. Replace both the washer and screw if worn.
Step 4: Check the O-Ring
Inspect the O-ring around the headgear body. Replace if cracked or damaged.
Step 5: Reassemble
Reverse the process to reassemble the tap, ensuring all connections are tight but not over-tightened.
For Ceramic Disc Taps
Step 1: Remove the Handle
Most ceramic disc taps have a small grub screw under the handle. Remove this to lift off the handle.
Step 2: Remove the Cartridge
Unscrew the large retaining nut and lift out the ceramic cartridge.
Step 3: Clean or Replace
Clean the cartridge with descaler or replace if damaged. Ceramic cartridges typically last 10-15 years.

Preventing Future Leaks
Regular Maintenance
- Don't over-tighten taps when turning off
- Replace washers annually in hard water areas
- Clean aerators regularly to prevent buildup
- Address small leaks quickly before they worsen
Water Quality Considerations
Hard water areas experience more frequent washer replacement due to limescale buildup. Consider a water softener if this is a recurring problem.

- Simple washer replacement: £50-£80

When to Replace Rather Than Repair
