How to Find a Water Leak in Your House

It’s important that every home owner knows how to detect a leak, either from visible signs or even the less obvious signs. If you don’t know how to detect a leak, you run the risk of wasting not just water, but your money too. By regularly checking your taps, pipes, and fittings you could save yourself water and money on your utility bill.


Leaks can occur in any home, regardless of its age, location or construction method. You may be able to visibly see signs of a leak, but sometimes, you might not.
Some visible signs include:

  • Sinks/Taps: Dripping taps. This could indicate a leak, but often it means that something like the washer needs to be replaced.
  • Kitchen: Look for water pooling under dishwasher or the fridge, warped or discoloured cupboards, bench tops or walls. If you see this, there may be water leaking somewhere nearby.
  • Bathroom: Check that the toilet cistern is continually running.
  • Laundry: is there pooling water under the washing machine or laundry tub? If you do see these, go ahead and check the washing machine hose for cracks, fraying or bulging.
  • Backyard: look for wet patches or random bright green areas of grass in your yard. If you find this, there may be a leak in one of the underground pipes.


If you’re unsure based on the visible signs whether you have a leak or not, you can follow these steps to find out:


#1: Turn off all running water in your house

#2: Find your water meter

#3: Take a reading of your water meter immediately (write down the red numbers on the top of your meter).

#4: Wait about an hour and make sure not to use any water at all and then take another reading.

#5: The Water Corporation website has a tool which you can use that will calculate whether you have a leak. You can find that tool here:
