Blocked Sink – Tips on clearing a blockage

Blocked Sink call Chiswick PlumbingPrevention is better (and cheaper) than cure.  Here are some tips to maintain your sinks and drains, keeping your water flowing and bad smells at away!



  1. Don’t pour grease or oil down the drain.  We all learnt at school that oil and water don’t mix, nothing has changed since then!  If you pour grease down the sink, over time it will coat the pipes, and clog up causing a bad smell and blocking your sink!  Egg shells are bad too!


  1. To dispose of fat or grease, wait for fat to solidify or oil to cool and dispose of it through recycling program or small amounts in garden compost or in a sealable jar in general waste.
  2. Use a sink drainer, you can pick them up cheaply from supermarkets or hardware stores.  These collect food scraps, hair and other nasties and stop them from clogging  up kitchen or bathroom sinks, simply empty it regularly into general waste.


  1. To unclog a kitchen sink with a plunger:  Put on rubber gloves, bail out the current liquid in the sink and pour into a bucket, then partially fill the sink quarter to halfway with HOT water.
  2. Position the plunger over the drain.  If you have a double sink, plug the unclogged drain side to ensure the plunger’s pressure is focused on the blocked drain.
  3. Work the plunger vertically up and down until the water starts to drain.
  4. Continue using the plunger until the clog is dislodged, it may take a while.
  5. If you don’t have a plunger on hand, you can also unclog your kitchen sink with vinegar and baking soda:
  6. As before, bail out any water that’s currently in the sink.
  7. Push 1 cup of baking soda with the back of a spoon down the drain.
  8. Pour 1 cup of white vinegar into the drain, and let sit for 5 minutes.
  9. Pour hot water to see if clog disappears, if not repeat baking soda and vinegar solution, careful if bailing out hot water.
  10. If your sink is still clogged, call Chiswick Plumbing 1300 55 2248
