Why Is My Swimming Pool Losing Water But No Leak Is Found?
Many pool owners panic at the sight of water loss, immediately fearing a costly leak repair. However, water loss does not always mean there is a structural leak. Before jumping into repairs, it’s essential to understand the reasons behind water disappearance, especially when no visible leaks are detected.
Common hidden causes of pool water loss include:
- Evaporation: The most natural and common cause, especially during hot, dry, or windy days.
- Splash-out: Water lost due to swimming activity or wind splashing water out of the pool.
- Backwashing: Water lost during filter backwash cycles.
- Hairline cracks or unseen liner tears: Small leaks that evade basic visual inspection.
- Underground plumbing issues: Leaks in pipes that do not saturate the pool structure immediately.
- Malfunctioning equipment: Skimmers, valves, or pool returns that cause water loss internally.
Identifying the exact cause requires a thorough inspection and specialized techniques — and that’s where NJ Pool Patcher excels.
