Where to look for a leak

Inside the home

Look in the kitchen, bathroom/s and laundry for dripping taps or leaking washing machine and dishwasher connections. Damp patches on the walls may also indicate a leak.

You can check your toilet cistern for leaks by placing a few drops of food colouring in the tank. Without flushing it, look for colouring in the toilet bowl. If it's getting through then you have a leak.

Outside the home

Look around at:

  • outdoor garden taps/hoses
  • garden irrigation (including sprinklers)
  • automatic solenoids and manual isolation valves
  • exposed pipe work
  • hot water systems and air conditioning units
  • damp and unstable brick paving and garden areas that may be moist and greener than expected.

Regularly test your garden irrigation system for leaks. Irrigation systems can often use the most water in a household and leaks in these systems can be costly. They are usually scheduled to run when there may be no one around to notice a leak. If you suspect your irrigation system has a leak, contact your local Waterwise Garden Irrigator.

Did you know?

  • A leaking tap can waste up to 10,000 litres of water a year.
  • A constant trickle into the toilet bowl wastes around 9,000 litres a year.

We may offer a reduction in your water use charges if you have had undetectable leaks repaired by a licensed plumber.

A leak allowance will be considered only after you have your plumbing or irrigation repairs completed to the required industry standards with all leaks repaired.

In the case of irrigation repairs, a manual isolation valve and master solenoid are mandatory.

You will need to make sure the licensed plumber or waterwise garden irrigator completes the leak allowance application form online or by downloading the paper based leak allowance application form, which provides us with details regarding the leak, once the repairs have been completed. For more information, read our Leak Allowance Policy.

The stop tap, which is found at the water meter, is installed to temporarily stop the flow of water when carrying out routine repairs and maintenance.

We understand that you may need to use this tap when an internal leak is present, however it is not a long term solution and the property owner should arrange to have the repairs completed as a matter of priority. 

Whilst we supply water to the property boundary up to the water meter, property owners are responsible for:

  • the cost of any water use registered on the water meter
  • all water used or lost through the internal water service
  • ensuring the internal water service is in good condition.

If you require water supply to the property to be turned off regularly, or for an extended period of time, a manual isolation valve must be installed on the internal pipework.
