Pentair Pentair Clean & Clear Plus Cartridge Pool Filter LID ORING LEAK Error Fix: Lid O-Ring Leak

Water is seeping from the junction between the tank lid and the tank body. The large O-ring that seals this joint has dried out, cracked, compressed flat, or become pinched during lid installation. Remove the lid, inspect the O-ring, clean the O-ring groove of debris, and apply silicone-based O-ring lubricant generously. Replace the O-ring if it is cracked, flat, or permanently deformed (approximately $10-20 for the O-ring). When reinstalling the lid, ensure the O-ring is seated properly in its groove before tightening the clamp.
