How do you find a leak in a pool?
A visual inspection of your pool is the first step to finding a leak. Examining the shell, liner or tiling can provide an indication of the source of your leak. If everything seems fine, then sonar leak detection technology can be deployed to find issues within your pipework—such as cracks, broken joints or root intrusion—that would otherwise be invisible to the naked eye.
How do you fix swimming pool leaks?
First of all, it's important to identify the type of leak. There are two basic types: a crack in a pool surface or a leak from a pool line, such as a supply pipe or return jet. To fix a pipe leak, first of all the location of the leak will need to be found using sonar or pressure testing, then the offending pipe will need to be dug up and repaired. This may require a new joint or replacement pipe. Cracks in the pools surface will often need to be fixed with appropriate relining.
How can I tell if my pool is leaking or just evaporating?
Evaporation is normal, but if your pool is losing more than a few centimetres of water per week, it’s likely a leak. Mark the water level overnight—if it drops noticeably, it’s time to get it checked.
Common Signs of a Pool Leak
Pool leaks can often go unnoticed until the signs become obvious. While a small amount of evaporation is normal, continuous water loss usually means there’s a problem. Here’s what to look out for:
- Water levels dropping faster than normal
- Air or gurgling sounds in the pool system
- Sand or dirt entering the pool through the returns
- Increasing power or water bills
- Cracked or shifting tiles near the pool edge
- Algae growth or cloudy water that’s hard to balance
- Damp patches or pooling water around pipes or equipment

If any of these sound familiar, it’s worth arranging professional leak detection before the problem gets worse.
