What You'll Need To Unblock a Sink

The 10 Steps to Unblocking a Sink

The following steps should be completed in order until the sink is no longer blocked. It may be that the initial plunging will solve the problem and you only need to proceed as far as step 4. Or, if the blockage is stubborn, you may require all 10 steps.

  1. Clean the plug hole – remove the plug and get rid of any dirt or debris.
  2. Create a seal – make sure the plug hole is covered in water, creating an airtight seal for plunging.
  3. Seal the overflow – using the dish cloth, block the sink’s overflow, again creating an airtight seal.
  4. Take the plunge – place the plunger over the plug hole and push it up and down whilst holding the dish cloth against the overflow and maintaining a good seal.
  5. Pour down baking soda and vinegar – If there’s still a blockage after using the plunger, it’s time to get out the baking soda and vinegar. Pour a little baking soda down the drain first, followed by one cup of white vinegar. Leave for a few minutes. You should hear a slight fizzing noise as this starts to work.
  6. Pour hot water down – once the baking soda and vinegar have fizzed away for a few minutes, wash the mixture down the drain using hot water.
  7. Use soda crystals – this step can be done in addition, or instead of the baking soda and vinegar. Dissolve about half a packet of soda crystals in boiling water and pour the mixture down the drain to remove built up residue.
  8. Locate the u-bend – if by this stage, the blockage still remains, then you’ll need to get your rubber gloves on and prepare to remove and clean the u-bend…
  9. Position the bucket under the u-bend – place the bucket or washing-up bowl under the first bend in the pipe under the sink ready to catch any water.
  10. Drain and clean the u-bend – Start unscrewing where the u-bend meets the bottom of the sink until water begins to drip out. Wait for the water to drain out into the bucket or bowl, before completely removing the u-bend. Get rid of any debris from the pipe and then reconnect. Your sink should be back in working order again.

If you have tried all of these steps and are still having problems with a blocked sink, then it’s time to call a qualified plumber. Replace Your Bathroom will be able to provide a solution for you.
