How to Fix a Blocked Sink with Wickes

Показать описание

A blocked sink is blocked generally because food or other waste is caught in the pipe below the sink, but it's normally very easy to fix. Learn how to unblock a sink with this step by step guide from one of our Wickes experts.

There are many ways to fix a blocked sink. One way is with a plunger or a product like the blaster cup:

1. Place the blaster cup over the plug hole.
2. Block the overflow with a wet cloth and pump.
3. After just a few plunges the blockage should clear.

Another way you can unblock a sink is with liquid drain cleaner. Following the instructions, pour into the plug hole and a fizzing action will occur. Repeat a few times and rinse with warm water.

If this doesn't work, you can use a plumber's snake. To use, carefully push the snake down the drain, twisting to help it around the U bend. When you reach the obstruction pull, twist and push to unblock and then rinse with cold water.

Finally, if the blockage still persists you may have to get underneath the sink and deal with the plumbing directly:

1. Please ensure the water is turned off and then place a bucket or container underneath the trap, to catch any remaining water you might spill.
2. Unscrew the two nuts that hold the trap in place (this may need to be done with a wrench).
3. Once the nuts are undone, remove the trap and empty the water below.
4. Rinse the trap out in a bucket or use a piece of stiff wire to unblock.
5. Replace the trap by retightening the nuts.
