Pentair Pentair Clean & Clear Plus Cartridge Pool Filter AIR VALVE FAIL Error Fix: Air Relief Valve Failure

The air relief valve on top of the filter is stuck, broken, or will not seal. When stuck open, the valve continuously leaks water or sprays a stream. When stuck closed, air cannot be bled from the filter after service. Over time, the valve spring corrodes and the O-ring degrades. Replace the air relief valve assembly (approximately $5-15). This is a simple unscrew/screw replacement on most Pentair filters.
