Licensed plumbers, gas fitters and drainers · Local since 2011
Find the leak before it finds your walls
A hidden leak can run for months before you notice a damp wall, a patch of lush grass or a bill that keeps climbing. Finding the exact spot early saves water and avoids damage to walls, floors and foundations.
Asflow uses leak detection equipment to locate leaks in pipes behind walls, under slabs and underground, so any digging is limited to the spot that needs it. We can then repair the pipe in the same visit where possible.

Signs of a hidden water leak
- A water bill that has risen with no change in use
- A water meter that keeps moving when everything is off
- Damp patches, stains or peeling paint on walls and ceilings
- Mould or musty smells
- Unusually green or soggy patches in the yard
- The sound of running water when no tap is on

Leak detection questions
How do I know if I have a hidden leak?
Check your water meter with all taps off. If it is still moving, you probably have a leak. A rising bill, damp patches and the sound of running water are other signs.
Can you find a leak without digging?
Often yes. We locate the leak first so any excavation is kept to the smallest area.
Do you repair the leak as well?
Yes. We can repair leaking pipes and fittings, including burst pipes.
Who is responsible for a leak?
Generally, leaks on your property are the owner’s responsibility. If you are unsure, check with your water provider or call us.
