I have a leak, how do I find it?

If your leak test showed that you have a leak then you need to investigate where the leak is located.

Inside your 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 your home

  • Look in your outdoor garden for dripping taps or hoses, and check irrigation systems (including sprinklers).
  • Other items to check include automatic solenoids, manual isolation valves and exposed pipe work.
  • Hot water systems and air conditioning units can sometimes leak, so make sure you check them for leaks.
  • Damp and unstable brick paving and garden areas that may be moist and greener than expected can be a sign of leak.

Irrigation systems

  • Irrigation systems often use the most water in a household and leaks in these systems can be costly.
  • Regularly test your garden irrigation system for leaks.
  • Try to be home when your irrigation system is scheduled to run so that you can detect a leak.

Frequently asked questions

All plumbing work carried out in WA must be completed by a licensed plumber or tradesperson working under the direction of a licensed plumber. You can search online for tradespeople who are endorsed as waterwise and are up-to-date on water saving plumbing practices.

Once the repairs have been completed, carry out the leak detection test again to confirm the leak/s have stopped.

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.

In the case of irrigation repairs, a manual isolation valve and master solenoid are mandatory. You can find a waterwise garden irrigator with our search tool.

You will need to make sure the licensed plumber or waterwise garden irrigator completes the online leak allowance application or they can download the paper based leak allowance application form, which will provide us with details regarding the leak, once the repairs have been completed. For more information please 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 you should arrange to have the repairs completed as a matter of priority.

It is in your best interest to ensure that there are no leaks inside or outside your property, as the property owner you are responsible for the cost of any water used.

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.
