A buried pool pipe can lose water without leaving a visible puddle. Soil, paving and the circulation system may offer clues, but testing is needed to separate pool plumbing from irrigation, drainage and other sources.

1. Damp soil persists in dry weather

Note where it occurs and whether nearby irrigation runs. A wet patch alone cannot identify the pipe or even establish that the pool is responsible.

2. Grass grows differently in one area

A greener strip over a possible pipe route is worth mentioning during an inspection. Compare it with irrigation coverage before assuming a leak.

3. Loss changes during circulation

A pattern linked to pump operation can help prioritise testing. Keep comparable records and ask for guidance before changing the operating schedule.

4. Air repeatedly enters the system

Lost prime or bubbles can indicate suction-side air entry. Equipment seals, cleaner hoses and a low pool level can produce similar symptoms.

5. Paving changes position

Sinking or lifting around the pool needs prompt attention. Water loss, drainage, roots and ground movement are possible causes. Keep people away from unstable areas.

6. Top-ups become more frequent

Check for backwashing, waste-line discharge and automatic top-up behaviour. A comparison bucket can help establish whether the loss exceeds evaporation.

7. Earlier surface repairs did not stop the loss

A repaired shell does not rule out a separate buried pipe defect. Send the previous scope and any test findings so the next investigation can build on them.
