Product details

The Pentair 355301Z is the genuine strainer pot lid for the Challenger and Pinnacle pumps, and for the AFP-75, AFP-120 and AFP-150 WaterFall Specialty pumps. It is the factory part, not a generic lid.

Why lids get replaced

The strainer pot lid takes sun, heat and repeated tightening. Over time it crazes, cracks or warps enough that it stops sealing. The result is usually an air leak: the pump struggles to prime, or holds prime for a while and then loses it. Since the lid is also what lets you see the basket, a clouded or damaged one hides how full the pot has become.

Order the seal with it

The lid o-ring is a separate part. If the old o-ring is flat, hard or split, replace it at the same time. A new lid on a tired seal will still pull air.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps does this lid fit?
The Pentair Challenger and Pinnacle high flow and high pressure pumps, and the AFP-75, AFP-120 and AFP-150 WaterFall Specialty models.
Does the o-ring come with it?
No. This is the lid alone. The lid o-ring is ordered separately, and it is worth replacing at the same time.
My pump will not hold prime. Is the lid the problem?
It is one of the first things to check. A cracked lid, or a lid sealing on a flattened o-ring, lets air into the strainer pot and the pump will keep losing prime.
Is it a genuine Pentair part?
Yes. It is the Pentair OEM lid, part number 355301Z.
