How to Fix a Kitchen Sink Tap Leak: Step-by-Step Guide

A dripping kitchen tap is more than just annoying—it wastes water and drives up bills. Fixing a kitchen sink tap leak is a simple, cost-effective task anyone can do with the right tools and guidance.

Begin by identifying where the leak originates—under the faucet, around the spout, or at the supply lines. Turn off the water supply, disassemble the tap carefully, and inspect washers, O-rings, and seals for wear or damage. Visual inspection often reveals the culprit without disassembly.

You’ll need an adjustable wrench, screwdrivers, replacement washers or cartridges (match the model number), plumber’s tape, and a cloth. Having the correct parts ready ensures a smooth, efficient repair without delays.

1) Shut off the water supply under the sink.
2) Remove the tap handle by unscrewing the cap and retaining nut.
3) Take out the valve stem and inspect internal components. Replace worn washers, O-rings, or cartridges.
4) Apply plumber’s tape to threads before reassembling.
5) Test the tap and monitor for leaks. Tighten gently—over-tightening can cause new issues.

Fixing a kitchen sink tap leak is a manageable DIY task that saves water and avoids costly repairs. With the right approach and tools, you’ll restore function and peace of mind. If the leak persists, consult a licensed plumber to ensure long-term reliability.
