Planning & preparation
Do it right
Staying safe
Step by step
Step 1
Start by turning off your water supply. To do this, locate the stopcock and turn it clockwise.
Step 2
Remove any cupboard doors that may block your access to the pipes and the underneath of the strainer.
Step 3
Place a bucket or watertight container underneath the strainer to catch any water that spills out.
Step 4
Unscrew the two compression fittings that hold the waste pipe in place. You may need to use a wrench if the compression fittings are particularly tight.
Step 5
Carefully remove the waste pipe and empty the water into the container below.
Step 6
Next, disconnect the overflow pipe from the side of the strainer.
Step 7
Remove the lower half of the strainer by unscrewing the screw that holds the top of the drain to the strainer. It’s best to reach underneath and hold the bottom of the strainer still whilst you do this.
Step 8
Now remove the lower half of the strainer unit.
Step 9
Then, lift the top of the strainer unit out from above.
Step 10
Use a cloth to thoroughly clean the parts and the area around the hole. Take care as the edge may well be sharp.
Step 11
To install the replacement strainer, start by placing the thinner, wider, rubber washer between the sink and the top part of the strainer.
Step 12
Then, put the thicker rubber washer and the bottom part of the strainer into position underneath the sink.
Step 13
Use a screwdriver to tighten the screw and secure the strainer in place.
Step 14
Reconnect the overflow pipe to the waste pipe, and then connect to the trap.
Step 15
Turn your water supply back on by twisting the stopcock anticlockwise.
Step 16
Finally, run the tap to check the leak has been resolved.
