Pool Losing Water
Before assuming a leak, understand what normal looks like here. In peak Bakersfield heat, evaporation of roughly a quarter inch per day is ordinary, and wind and low humidity increase it.
Likely Causes
Evaporation
The most common answer between June and September. Uncovered pools with water features lose considerably more.
Splash-out and backwash
Heavy use, aggressive water features and routine backwashing all remove real volume.
Equipment pad leaks
Pump seals, filter tank bands, valves and unions can lose steady water while the system runs.
Plumbing leaks
Underground line failures often show as loss that continues even when the pump is off, or wet ground near the run.
Structural leaks
Cracks, failed skimmer throats and worn light-niche or fitting seals.
Autofill malfunction
A stuck autofill can mask a leak entirely — or add water continuously and hide the problem on your bill instead.
What You Can Safely Check
- Run a bucket test: a filled bucket on a step loses water only to evaporation; compare the drop to the pool over 24 hours
- Note whether loss continues when the pump is off
- Check the pad for wet ground and the yard for unusually damp areas
- Confirm the autofill is functioning normally
When to Call a Professional
If the bucket test shows the pool losing meaningfully more than the bucket, there is a leak. We start with the accessible components — pad, fittings, skimmer, light niche — before recommending excavation or specialized detection.
