About the Pentair Posi-Clear RP
Pentair's 2021 parts catalog lists the Posi-Clear RP cartridge filters (PXC series heading) in three sizes: 100, 150 and 200 sq. ft. The lid, center core and cartridge element depend on the size; the rest of the list is shared.
Repair or replace?
Most of these parts are replaceable on their own, which is why it matters which one has actually failed before anything is ordered. Whether a repair or a new pump makes more sense depends on what failed and the condition of the rest of the pump. Pool Filter Repair & Installation · Pool Equipment Replacement & Upgrades
