5 Signs Your Pool Has a Hidden Leak
Losing more than a quarter inch of water per day? Here are the warning signs to watch for before damage spreads.
Is your pool actually leaking?
A small leak ignored for months becomes a structural problem. Look out for these five signs:
- Water loss over 1/4" per day — anything more than evaporation is a leak.
- Wet spots in the yard — soft, soggy ground near the pool equipment.
- Cracks in the deck or coping — settling can indicate water undermining the shell.
- Air in the pump basket — a suction-side leak pulls air into the system.
- Rising chemical use — fresh water dilutes your chemistry constantly.
If you see two or more of these, request a leak detection visit.
