Step 6 – Flush with hot water
When the baking soda and vinegar begin to work, you will hear a fizzing sound. Leave for a few minutes, then turn your bathroom sink faucets on to wash the mixture down the drain using hot water.
Step 7 – Use the soda crystals
You can also use soda crystals to unblock the sink. Dissolve half a packet of soda crystals into boiling water, and pour the mixture down the drain to help eliminate soap scum and grime.
Step 8 – Clean the U-bend
If none of the previous methods have worked, remove the U-bend and clean it out thoroughly.
Step 9 – Grab the bucket
Identify the first bend in the pipe under the sink, and place a bucket or washing-up bowl underneath the U-bend to catch any water.
Step 10 – Drain the U-bend and inspect
Unscrew the fitting where the U-bend meets the bottom of the bathroom sink. As the water starts to drip out, cease unscrewing and allow the water to drain into the bucket or washing-up bowl. Once the water has drained, remove the U-bend completely and look inside it. Remove any debris from the U-bend and clean it out thoroughly. Re-connect the U-bend, and your sink should no longer be blocked. Water from your luxury faucets should flow through freely. If none of the above steps have solved the problem, we recommend enlisting the services of a qualified plumber.
