Frequently Asked Questions
What does the Pentair 357149 include?
The 3 HP wet-end / housing assembly for WhisperFlo and compatible IntelliFlo pumps. Confirm exactly which components ship with your unit and which of your existing parts (seal plate, impeller, hardware) transfer over.
Which pumps does it fit?
Pentair WhisperFlo and select IntelliFlo pumps rated at 3 HP. Because wet-end fitment depends on horsepower and pump family, verify your pump model and HP on the motor label before ordering.
How is this different from the 356175Z?
Both are wet ends, but for different pumps. The 357149 fits WhisperFlo and select IntelliFlo (3 HP); the 356175Z is the IntelliFlo3 wet end. Match the part to your exact pump.
When should I replace the wet end instead of the pump?
When the housing or volute is cracked or leaking but the motor still runs well. Replacing the wet end is far more economical than a complete pump.
Is this a genuine Pentair part?
Yes — genuine Pentair OEM, so it seals and flows correctly against the factory motor and seal plate.
Does it need professional installation?
Pump service is best done by a qualified professional. Disconnect power, relieve system pressure, and replace disturbed O-rings and the shaft seal during the swap.
