How to unclog a sink

Unclogging a sink could be a very simple task if the blockage is minor and very localised to the plug hole. 

If you are attempting to unblock the sink using a plunger:

  • Coat the edge of the plunger’s cup with vaseline (petroleum jelly) to improve suction
  • Add a couple of inches of water to the sink to also aid suction
  • Also cover the overflow holes with a damp cloth if possible to help build up pressure

Do’s & Don’ts of what to put down your sink:

  • Do not ever pour fat down sinks – over time this will solidify and lead to potentially bigger problems
  • Do not wash food debris down the sink – this will inevitably lead to a blockage
  • Make sure you regularly remove hairs from plug holes in sinks, baths and shower
