Common Problem
Pool Filter Leaking? Common Causes and Next Steps
Filter leaks are often solvable without a full replacement. Common culprits include the tank o-ring, clamp band or multiport spider gasket — all wear parts stressed by Miami's constant humidity.
Most likely causes
- Failed tank o-ring
- Loose clamp band
- Cracked multiport valve
- Split lateral or manifold
What to do now
Shut the pump off, mark where water is coming from, and consider scheduling filter service. Never tighten a pressurized clamp band.
