Key points


  • To unblock your sink, make sure there’s some water in the sink and put a sponge over the overflow hole. Then use up and down motions with the plunger.
  • If it unblocks, you’ll know because the water will go down the sink.
  • If this doesn’t work, you’ll need to take the u-bend apart underneath the sink. Use gloves to do this and put a bucket under the u-bend, as water will come out. Twist to undo these two nuts and tip any excess water out. You may need to unblock the U-bend.
  • Once it’s cleared you’ll need to reattach it. Make sure the rubber seals are still on the U-bend, otherwise it will leak. If they’re damaged, you can buy replacements from your local hardware store.
  • Put the u-bend back in position and retighten the nuts and then run the tap to ensure the blockage has been cleared.
