A leaking pool isn’t always obvious. Water loss can be gradual, easy to dismiss as evaporation — but left unchecked it can cause serious damage to your pool structure, surrounding groundwork and equipment. If your pool is losing water and you’re not sure why, professional leak detection is the fastest way to find the problem before it gets worse.
Is it a leak or just evaporation? A simple water loss test will tell you. Mark your current water level — either by counting tile rows, noting the tile pattern, or using waterproof tape on a liner pool — and check it again after 24 hours. If the level has dropped noticeably, it’s worth investigating further. If you suspect a leak — we can help find it.
Signs your pool may be leaking
💧
Water level dropping consistently
Losing more than 1–2cm per week even in cool weather is a strong indicator of a leak.
💰
Water bills increasing
If you’re topping up more frequently than usual your pool could be losing water underground.
🌱
Wet ground around the pool
Soggy or unusually green patches near the pool or equipment room can indicate a pipe leak.
⚗️
Chemicals constantly out of balance
A leak dilutes your water constantly, making it very hard to maintain stable chemistry.
How we find the leak
01
Visual inspection
We start with a thorough inspection of the shell, fittings, skimmers, returns and equipment room to identify any obvious signs of water loss.
02
Pressure testing
We pressure test your pipework systematically — circulation lines, suction lines, return lines and drain connections — to pinpoint exactly where the loss is occurring.
03
Report & next steps
Once located we’ll explain exactly what we’ve found, where the leak is and what the repair options are — clearly, without jargon.
What we test
🔵
Main circulation pipework
Pressure tested to identify any loss in the primary circulation lines running to and from the equipment.
🔵
Return & suction lines
Both return and suction pipework tested individually to isolate the source of any pressure loss.
🔵
Skimmer & drain connections
Skimmer bodies, main drains and associated fittings inspected and tested for leaks.
🔵
Equipment fittings & unions
Pump, filter and heater unions and fittings checked — a common source of slow leaks often missed during routine maintenance.
