The equipment pad got flooded and most of the pool equipment was under about 2' of water for a period of time overnight this past summer. Everything still worked the next day but both the regular pump and the Polaris booster pump seemed noisier. The pad is - below - the level of the pool, maybe 2' or so.
The booster got quite noisy and also started to leak. We contacted a local PB/repair company who said they only replaced booster pumps and would not repair, so that's what we did.
Now that the booster is quiet again, the noise from the main pump is more noticeable and seems to be getting a bit worse as time has gone on. Seems to work OK, though. It's not really a metallic noise, but rather a loud WAH-WAH-WAH-WAH that kind of ruins one's enjoyment of the backyard.
Any ideas on whether the pump is repairable and where we should start? We're coming up on the pump's 4th season but the pool stays open year 'round with the pump getting a workout on those nights/days when the temps drop below freezing. The pump is also only a single speed, uprated pump that's probably oversized to our pool, so perhaps we could get some energy savings switching it out.
We have a waterfall that's not in my signature. Oh, and the pump's a Pentair Challenger High Pressure 2.0 HP. Any help/thoughts would be most appreciated.
