How to replace a tap washer

  1. Turn off the water supply. Some sinks will have an isolation valve underneath, otherwise turn it off at the mains.

  2. If you’re here to find out how to change a tap washer on a mixer tap or hot water tap, turn off the boiler and immersion heater, too.

  3. Put the plug into the plug hole. That way, you won’t lose screws or tap parts.

  4. Place an old towel, cloth or rags into the sink to protect the surface against parts being dropped.

  5. Use the screwdriver to remove the tap cover.

  6. Once the valve is exposed, remove it with the spanner. For stubborn valves, cover it with a cloth and use a wrench.

  7. Beneath the valve is the tap washer, which will be secured with a screw or nut.

  8. Using a spanner, remove the tap washer. For stubborn washers, use a penetrating oil to soak the area and loosen the washer.

  9. Replace the old washer with a new one, ensuring that it is the same size.

  10. Replace the tap parts in the same order you removed them. Take care not to overtighten the valve to prevent causing damage.

  11. Once the water is turned back on, you should have a perfectly working tap once again! If you’ve changed the washer because the tap was leaking, and you’ve still got the same problem, read our article on how to fix a leaky tap.
