I'm looking to purchase a new pump. I don't know the HP of the old pump. The sticker is gone. Please see below for more pool specifics.
I have found a used WhisperFlo pump locally for a good price. My concern with it is that it is oversized for my pool. It is a 1 HP model WF-4C. According to Pentair customer service I only need the 1/2 HP model. Is there a reason not to use this pump other than spending more money on electricity than I need to? Thank you.
