I have an FNS Plus 48, installed in March 2013. Recently, it developed a leak where, or very near to, where the top and bottom meet. I am not sure how to best proceed and am hoping for insight. I've replaced the gasket (lubing it liberally), and it still leaks. I've inspected the band clamp and...

I have found conflicting info on the web, so I am hoping someone here knows for sure -- should the gasket that seals between the top and the bottom of the filter tank on a Pentair FNS Plus be trapezoidal shaped, or round? I've found people selling supposedly the same Pentair part number, with...

Last weekend, I returned home from a trip and found my pump circuit breaker tripped and the relay not working (doesn't switch, test button stuck in the down position). I ordered a new one and in the interim moved a relay of the same model from another circuit. Everything seemed to be working...

I have 2 WhisperFlo pumps for waterfalls that weren't used all summer (they were last used when the anti-freeze cycle activated, likely in March or so). Last week I tried to use them, and neither turned over -- they just hummed. I disassembled one of them, verified no blockage, and that the...
