Stop the drip: How to change a tap washer in 10 easy steps
A dripping tap can lose up to 2L / hour, 48L / day, 336L / week, water is far too precious to waste so follow the
tips below or call a licenced plumber to properly service all of your household taps.
Make sure you have a new tap washer (one that is the correct size for the tap you are fixing) ,
a shifter, a multi grip tool and some silicone.
Turn off the water at the mains, release water from the pipes at the nearest garden tap
and then at the tap you are changing
Remove the handles and the flange (use the multi grips, if it is a bit tight) scrape away old silicone.
Unscrew the spindle, replace the body washer if it is worn
The brass seat that the tap washer sits on needs to be re-seated back to brand new, a good plumber
would carry a re-seating tool with them and do this if they were changing the washers or you can purchase
a cheap one from the hardware shop (but they may not work as effectively)
Remove the old tap washer and replace it.
Screw the spindle back on make sure the tap off.
Turn on the mains outside and return to the tap you were just working on to check for leaks.
Once you are happy there are no leaks, it is a good idea to re-seal around the spindle with some more silicone,
especially if the tap is in the shower, preventing water damage inside the wall.
Assemble the tap as it was, flange, handle and tighten button with a spanner
Mission accomplished, now check your other taps
For safety: If your hot water is in the ceiling, call a licenced plumber
