Quick overview

  • Chemical resistant Molded to stand up to pool chemistry better than a standard clear lid.
  • Blue tinted PVC Tinted rather than fully clear, so you can still see the basket and the water level.
  • WhisperFlo fitment Pentair lists it as the chemical resistant lid for the WhisperFlo pump.
  • Genuine Pentair Factory part 357156, not an aftermarket lid.
  • Fixes a crazed lid A lid that has gone cloudy, crazed or brittle will not hold prime and is the usual reason for an air leak at the pot.
  • Lid only Supplied as the cover; the clamp and lid o-ring are separate Pentair parts.

Product details

The Pentair 357156 is the chemical resistant strainer cover for the WhisperFlo pump, molded in blue tinted PVC. It is the genuine Pentair part.

What the chemical resistant version buys you

Pump lids live in a hard spot. A pot that sits near a chemical feeder, or takes splash at the equipment pad, attacks an ordinary lid until it goes cloudy, crazes and eventually cracks. This cover is molded to resist that, and the blue tint keeps enough visibility to check the basket and the water level without opening the pot.

When to replace

A crazed or distorted lid stops sealing, and the pump then draws air instead of water. If the pump is losing prime, running noisy or showing air in the pot, look at the lid and the o-ring before chasing the plumbing.

What is included

The cover only. The lid o-ring and the clamp are separate Pentair parts, and it is worth fitting a fresh o-ring while the lid is off.

Questions and answers

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

Which pump does this lid fit?
Pentair lists 357156 as the chemical resistant lid for the WhisperFlo pump.
Is the lid see through?
It is tinted blue rather than water clear, so the basket and water level are still visible through it.
Does it come with the o-ring and the clamp?
No. This listing is the cover on its own. The lid o-ring and the clamp are separate Pentair parts, and a lid change is a good time to replace the o-ring.
Why would I choose the chemical resistant version?
A pump that sits downstream of a feeder or gets chemical splash at the pad wears out an ordinary lid faster. The chemical resistant molding is made for that duty.
