Compare water loss with normal pool use
Rainfall, evaporation, splash-out, cleaning and automatic filling can obscure a water-loss pattern. Note the dates, water level and what the equipment was doing. Avoid assuming a single daily water-loss threshold diagnoses every pool.
A bucket test can help identify a pattern
A comparison between water loss in a bucket and the pool can help separate evaporation from a possible leak. Ask your provider for a suitable procedure for your pool, and account for rainfall, filling and pool use. A greater drop in the pool is a reason to investigate; the comparison does not locate the source.
Useful details for a leak specialist
- Does the pattern change with the pump running?
- Has the waterline settled at a particular height?
- Are there damp areas near equipment or plumbing?
- Was any equipment, deck or pool work recently completed?
- Do you have an earlier detection report?
Choose the next step
If the source is unknown, start with pool leak detection. If a test has already located it, share the report when asking about pool leak repair. Do not drain the pool or excavate plumbing just to investigate.
