Pool Leak Detection Melbourne: How to Tell If Your Pool Is Leaking

Is Your Pool Actually Leaking?

Melbourne pools can lose water to evaporation, splash-out, and backwashing — especially in summer. Before assuming a leak, it's worth doing the bucket test to confirm water loss is above normal evaporation rates. Fill a bucket with pool water and place it on the first step. Mark the water level inside the bucket and the pool water level on the outside. Wait 24 hours without running the pump. If the pool has lost significantly more water than the bucket, you likely have a leak. Normal evaporation in Melbourne is typically 2–3mm per day in summer. Consistent losses above 5–6mm per day suggest a leak.

Common Sources of Pool Leaks

Pool leaks typically occur at fittings and penetrations — light fittings, return jets, skimmer boxes, and main drains are all common failure points. Leaks can also occur through cracks in the pool shell, delamination of the pool surface, or in the underground pipework connecting the pool to the equipment. Pipework leaks are the most difficult to locate because the pipes run underground and can be anywhere between the pool and the pump/filter equipment pad.

How ATC Plumbing Finds Pool Leaks

We use a combination of pressure testing and acoustic leak detection to locate pool leaks precisely without unnecessary excavation. Pressure testing isolates individual pipe runs to determine which section is losing pressure. Acoustic detection then pinpoints the exact location of the leak by listening for the sound of escaping water through the ground. This approach means we can identify the leak location within centimetres — and excavate only where needed.
