Problem
Pool Losing Water
Ref R500 – R3 500 pool detection
Pools lose water every day to evaporation, and the amount changes with wind and heat. A marked bucket test establishes the real loss in 24 hours; after that, pressure isolation of the suction and return lines separates a plumbing failure from a shell or fitting leak.
Likely causes
What is usually behind this
- Underground suction or return line failure
- Skimmer, light niche or main drain fitting leak
- Crack or porous patch in the pool shell
- Hydrostatic valve or sump fault
- Autofill valve running continuously
- Evaporation mistaken for a leak
Safe checks you can do now
Before the technician arrives
- 01Run a bucket test for 24 hours beside the pool
- 02Mark the water level on the tiles and compare daily
- 03Check for air in the pump basket and lost suction
- 04Look for wet or sunken paving along the pipe route
Do not open walls, lift tiles or excavate before the leak is located — it multiplies the repair cost without improving accuracy.
