Blocked Sink Solutions

A blocked sink or plug hole leads to slow draining water and bad smells, yet it's easy to unblock a blocked sink. Here's how to fix that sink blockage and get your sink draining correctly again.

Step 1: Unblocking Tools You Will Need

  • Sink plunger
  • Cloth
  • Pair of grippers
  • Bowl
  • Strong wire (tip: a wire coat hanger will do)

Step 2: Sink Plunger

Plug the overflow with a damp cloth or something similar to stop air escaping and put a little water into the blocked sink. Push the plunger down over the plughole of the blocked sink and pump several times. The suction caused by this should remove the blockage and the water should easily drain away. Squirt a little disinfectant down the plughole of the blocked sink to finish the job off.

Step 3: The Pipes

If the sink plunger didn't unblock the blocked sink you'll have to dismantle the pipes under the blocked sink. Don't panic, this is easier than it sounds!

Put a bowl underneath to catch any dirty water first or it'll end up on your floor. You will either have a U-bend or a bottle shaped trap. With a U-bend unscrew the retaining nuts at either end.  With a bottle trap, unscrew the whole thing. Once removed, use your fingers or a piece of wire to poke out any blockage in the pipes.

BEWARE: Not only does it look grim but it will also stink. Rinse the pipes well to get rid of every last bit of dirt.

Step 4: Reassemble

Put the system back together, firmly tightening all nuts.  Chuck the dirty water down an outdoor drain and not back down the unblocked sink. Lastly squirt a little disinfectant down the plughole to finish the job off.

Step 5: Call The Professionals

If, after following the above steps, you are still experiencing a blocked sink, it's possible that your problem is further up the plumbing system and could be external to your property.
