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:

  1. Water loss over 1/4" per day — anything more than evaporation is a leak.
  2. Wet spots in the yard — soft, soggy ground near the pool equipment.
  3. Cracks in the deck or coping — settling can indicate water undermining the shell.
  4. Air in the pump basket — a suction-side leak pulls air into the system.
  5. Rising chemical use — fresh water dilutes your chemistry constantly.

If you see two or more of these, request a leak detection visit.
