How to check for water leaks

If your water bill unexpectedly increases but your water usage has not changed, it could mean you have a leak.

To check for a leak, turn off your taps on your property. If water use dial is still spinning, you have a leak and need to call a plumber.

If you are unable to find the leak, we suggest you contact a licensed plumber to detect and repair the leak for you.
