How do I detect if I have a leak?

Signs of a leak include:

  • Higher-than-usual meter readings
  • Damp patches around your property
  • Areas in your garden where plants or grass continue to grow through a dry spell
  • Loss of water pressure
  • The sound of running water in your property when none is being used

To detect a leak, follow the steps below

  1. Turn off all your appliances in your property which use water and all of your taps to ensure no water is being used.
  2. If it is safe to do so, take a look at the silver dial in the middle of your water meter:
  3. If your dial is spinning when everything is turned off then this could indicate you have a leak

If you have an internal leak, it is your responsibility to get it fixed. It is important you repair the leak as soon as reasonably possible, as you may be eligible for a leakage allowance.
