Most frequent questions and answers

Kitchen Sinks –

Fallen Leaves into the sink drain usually located outside the property from where the kitchen waste pipes run can cause the sink to block up.

Build up of fat and food waste.

Detergent from washing machines if they are run into the same waste system can cause issues by forming hard scale in the pipe work.

Bathroom Sinks –

Build up of hair in the system .

Shampoos , soap and other sanitary items used can build up scale in the pipes.

Sometimes your blocked sink could be due to an external drain being blocked. We will check the inspection chambers when necessary. Things like tree roots and debris can potentially cause sinks to block further along in the system.



You can try the following method but if it doesn’t work you are better off calling a professional to deal with it, as it can cause more problems if you keep putting “drain clearance” substances down the sink:

To try clearing a blocked sink you will need:

  • White vinegar and baking soda, liquid drain un-blocker
  • A bowl or bucket
  • A Plunger
  • A cloth
  • Rubber gloves

1) – Clear the plughole

Remove the plug by unscrewing it and clear out any sludge of debris that may be blocking the pipe

2) – Make the plughole airtight.

Submerge the plughole in water to create an airtight seal before using the plunger.

3) – Seal off the overflow

Us a cloth to block the overflow and create a seal that is airtight.

4) – The plunger

Position the plunger over the plughole and push it up and down gently while keeping the cloth over the overflow to maintain a good seal.

5) – Vinegar & baking soda, or liquid drain unblocker.

If the plunger doesn’t free the blockage, you could try using the vinegar and baking soda or a liquid drain unblocker. Pour some baking soda down the drain, and then a cup of white vinegar to follow, or pour the drain unblocker down the plug hole.

6) – Hot water

You should hear “fizzing” when the vinegar and baking soda react. After a few minutes, pour hot water down the sink to flush it through.

7) – The u-bend

If the above has not worked try removing and cleaning out the u-bend.

8) If none of the above methods are successful, you should call a professional drain clearance company. DrainBoss offer a local 24 hour service.

We have experienced engineers that can quickly unblock your sink. It usually takes no more than an hour, however with bathroom sinks depending on the access ( if behind boarding for example ) it can take slightly longer.


We have all the equipment necessary to clear the sink on our vehicle. We use high pressure mini jets, electro mechanical cable machine and suction vacs.

Unfortunately, if left, it will start to back up in other areas of the same drainage run and can cause issues further in the system with possible spillages and flooding.

We have a fixed price for clearing a sink. Call our friendly advisors and will provide a price to you, depending on the access and other factors.
