Product details
The Pentair 357227 is the replacement lid for Pentair and Sta-Rite OptiFlo pumps. It is a new OEM part.
Why the lid matters
The strainer pot lid is a pressure seal, not a cosmetic cover. When it cracks, warps or no longer seats evenly, the pump draws air at the pot instead of water, and the symptom on the deck is a pump that will not hold prime and a pot that never stays full. Lids also cloud and craze with age and sun, which is a smaller problem but a real one, because a lid you cannot see through hides a basket that is packed with leaves.
Before you order
This is the lid on its own. Look at the lid o-ring while the old lid is off, since a flattened or cracked seal will let air past a brand new lid. Our source notes the lid may suit other Pentair pumps but does not list them, so order against the part number.
