Faulty washers can mean dripping taps, wasted water, and increased bills. Thankfully, changing the washer on a mixer tap is a straightforward task that can be done with a few basic tools. This guide will walk you through the process step-by-step, ensuring you can fix that drip and enjoy a fully functional tap in no time.

Essential Tools & Equipment

Step 1: Turn Off the Water Supply

  • Before starting any work on the tap, ensure that the water supply is turned off – the stopcock is usually found under the kitchen sink.

  • Once turned off, drain the tap to remove any residual water.

Step 2: Remove the Tap Handles

  • Carefully take off the tap handles using a screwdriver if necessary.

Step 3: Detach the Tap Unit

  • Under the tap handles, you’ll find the tap units.

  • Using an adjustable spanner, loosen the screw to remove the tap unit.

Step 4: Inspect and Replace the Washers

  • At the bottom of the tap units, you'll find the washers. 

  • Check them for any signs of damage. 

  • If they appear worn out, gently remove them using a screwdriver and replace them with new ones. 

  • Ensure that the replacement washers are of the same size. It's a good idea to replace all the washers while you're at it.

Step 5: Reassemble the Tap

  • Once the washers have been replaced, it's time to reassemble the tap. 

  • Ensure all parts are securely tightened, but be careful not to over tighten as this can cause damage to the tap.

Step 6: Turn the Water Supply Back On:

  • After reassembling the tap, turn the water supply back on and check for any leaks.
