Frequently asked questions
How do I know which pump part I need?
Pool pump families share housings but differ internally by horsepower and revision. Use the part number from the exploded parts diagram for your exact pump model rather than picking by appearance - impellers in particular are horsepower specific.
What is the part number for this pump part?
Pentair lists this pump part under part number 350305S. Quote 350305S when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Should I replace the seal at the same time?
Whenever a pump is opened up, replacing the shaft seal and the housing O-rings at the same time is standard practice. The parts are inexpensive relative to a second teardown, and old seals rarely reseat properly once disturbed.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
What causes this part to fail?
The usual culprits are running the pump dry, debris passing through a damaged basket, and chemical attack from unbalanced water. Fixing the underlying cause matters as much as fitting the replacement, or the new part will fail the same way.
Is there a warranty on this pump part?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
