Usually, it all comes down to simply knowing the answer to the question “how do you change a tap washer?" While most of us weren’t taught this at school, it’s an easy skill to pick up.

Before learning how to replace a tap washer, be sure to identify which type of tap you have. Not every style can follow the standard instructions.

How to change a tap washer

Before you start learning how to replace a tap washer, you need to know where to find it. A regular tap washer is actually made of two main parts: the washer seat and the actual washer. The washer sits just above the seat and is a circular device that’s generally larger than the seat. Once you’ve found it, here’s how to change it in a standard tap:

  1. Turn off your water supply.
  2. Use a screwdriver to remove the tap’s cover, before removing the inner valve with a spanner.
  3. Beneath the valve you’ll find the tap washer.
  4. Remove the washer with a spanner, using a little penetrating oil if it’s stiff.
  5. Replace the washer with a new one in the same size.
  6. Put the rest of the tap back together again. Easy!
