Been having a few problems lately. First, my heater's unitherm governor blew out, and in the process I discovered the heater is shot. Right after, I noticed my sand filter is also leaking. And now my pump has gotten super loud.
It's a 2hp whisperflo (here's a pic: http://imgur.com/43ZemhG ). I've watched a few videos for "loud whisperflo" and all of them sound lower pitched than the sound this is making. It's extremely loud, and I'm able to hear it inside the house. (The pump sits all the way across the backyard!)
We've also had a handful of freezing nights since this all started. Wondering what the issue might be and what might have caused it? (The heater, the cold, etc?)
