Kitchen Tap Repair
Overview
Stop a kitchen tap from dripping or sticking by replacing its worn cartridge or washers.
Skill level: 3 / 5 (confident DIYer).
Typical duration: 1 – 2 hours hands‑on.
Safety First
Scalding water – isolate hot and cold supplies; wait for pipes to cool.
Sharp edges & small parts – wear cut‑resistant gloves and keep a parts tray nearby.
Pressurised splash‑back when reopening valves – open tap slowly while shielding eyes.
Slips under the sink – place an absorbent towel and use knee pads for stability
Tools & Materials
Item | Purpose |
Adjustable spanner or basin wrench | Loosen supply nuts and retaining collars |
Allen keys / screwdriver | Remove handle grub screws and escutcheons |
Replacement cartridge / washer kit | Cure leaks and stiff operation |
Silicone grease | Lubricate O‑rings and threads |
Old toothbrush & white vinegar | Clean limescale from spout and internals |
Towels & small bucket | Catch residual water |
Step‑by‑Step
1 – Shut off supplies & drain
Why: Prevents water spray when the tap body is opened.
Pro‑tip: Photograph the pipework layout before touching anything (1 of 3).
2 – Remove tap handle and cover
Why: Exposes the retaining nut or cartridge for access.
3 – Extract cartridge or valve assembly
Why: The ceramic discs or rubber washers inside are the usual leak source.
Pro‑tip: Note the orientation of old parts so the new cartridge seats correctly (2 of 3).
4 – Clean seating & spout
Why: Debris or limescale on the valve seat can cause new seals to fail.
5 – Install new cartridge / washers
Why: Restores smooth action and watertight seal.
Pro‑tip: Apply a light smear of silicone grease to O‑rings for easier future removal (3 of 3).
6 – Reassemble and test
Why: Confirms leak‑free operation and correct handle alignment.
Completion Checks
Tap operates smoothly with no drips at spout or base.
Handles align to original positions and stop firmly.
No water droplets under the sink after 5 minutes pressurised.
Aerator flows evenly without sputter.
When to call a pro instead
Call a qualified plumber if isolation valves are seized, the tap connections are inaccessible behind rigid pipework, or you discover corroded supply lines that need cutting and re‑soldering; professionals have the tools and insurance to handle these risks quickly and safely.
