My pool pump is a 2 hp whisper flo which I have had fir over 12 yrs. How do I know which gasket I need?

A  Answered on 4/27/2015 by InyoPools Product Specialist Patrick P.

Hi Richard, There have been two lids used on the Pentair Whisperflo pumps over the years and each use a different gasket. For Whisperflo pumps before November 1998 they used a stainless steel band clamp to secure the pump lid and this style lid uses The Old Whisperflo Lid O-ring. For Whisperflo pumps after November 1998 they used a plastic locking ring to secure the pump lid and this style lid uses The New Whisperflo Lid O-ring. I hope this helps!

Air leak

Had air leaking under the cap into the pump filter basket. I remove the dome cover, cleaned thoroughly and installed new gasket. This repair was easy and worked fantastic. I no longer have air in my filter basket in front of the pump.

Were these instructions helpful?
