If your meter reading increased using the above test, you should try to find where the leak is.
Taps and sinks – check to see if any taps are dripping. Dripping taps often just need a replacement washer.
Kitchens - check to see if there is water pooling under a dishwasher or fridge (if it is connected to the plumbing). You should also look for warped or discoloured cupboards, bench tops or walls. This is a sign that water is leaking from somewhere close by.
Bathrooms - check to see if the toilet cistern is continually running. If it is you’ll need to contact a licensed plumber to help you fix the problem.
Outside areas – if you can see wet patches or bright green areas of grass in the areas surrounding your property, this could indicate that there is a concealed leak in a pipe underground. Other things you can look for include
- Water in a drain when there hasn’t been any rain and it would normally be dry.
- Water dripping form an overflow (eg hot water system).
If you think you have a leak, and a plumber is needed, you will be responsible for the cost. You will also be charged for the water that is on your property while the leak remains unrepaired.
