Detecting and reporting a leak

Some leaks are quite easy to see or hear. Like a dripping tap, a leaking toilet or new wet patch on your lawn. Other leaks are not as easy to spot, and you may not notice it until your next water bill.

What are some common signs of a water leak?

Leaks can happen inside or outside your home, and knowing the signs can help you catch them early:

• Outside: Look for damp soil, unusually green patches of grass, or wet paths on brickwork or concrete.
• Inside: Damp, warped, or discoloured walls, floors, or carpets can indicate a hidden leak.
• Appliances: Watch for drips from your hot water system, evaporative air conditioner, or water pooling under the dishwasher or in cupboards.
• Toilet cistern: A running toilet can waste up to 260 litters of water a day. Add food colouring to the cistern, and if it shows up in the bowl without flushing, you have a leak.
