Hello TFP community,
My Pentair WFE-6 WhisperFlopump started making a loud rattling/humming sort of sound that definitely is not right. I shut it off worrying some damage may be or will be occurring if I let it continue to run, even though it was still pumping. I have found a exploded view of the pump and parts, and am hopping the subject matter experts here could pass on some educated guesses as to what may be faling. Maybe the impeller, or a bearing? When I power on the unit it runs quiet for the few seconds before the water starts hitting it, then the noise begins.
