How to find and fix leaks

The 3-Step Leak Check

Step 1: Ask people in your home not to use water while you do the test, and make sure that there is no water being used in your home i.e. that the washing machine is not on.

Step 2: Go to your water meter and take a reading of the last two red digits on your water meter - write it down or take a photo.

Step 3: Wait 5 minutes – remember not to use any water during this time. Take a reading of the last two digits in red. If there was any movement of the dial, you may have a leak.  Even the smallest movement can add up to a lot of wasted water over a year.

Reminder: It’s a good idea to do the 3-Step Leak Check every few months. Perhaps set yourself a reminder, such as when your bill arrives.

Where should I check for leaks?

  • Leaks can occur regularly in the garden - check for wet patches, green spots, popped off drippers, joiners or disconnections in the garden irrigation system every couple of weeks.
  • Inside the home, check for dripping taps and shower heads.
  • Leaking toilets can leak far more water than a tap – sometimes up to hundreds of thousands of litres a year being wasted. You can checks by listening for any noise or water movement in the bowl, or by putting food dye in the cistern and seeing if it ends up in the bowl - see the video above for a demonstration.

I’ve found a leak, how do I fix it?
