I have a Haywood s200t filter. It was fine last year. Open the pool up and start the pump motor blows up in less then a day. So I get a new motor and start it up. Then it starts losing flow on returns dumping back into pool. Back wash and it helps for a 1/2 hour then back to no flow. It's pumping in the pumps skinner. So then I try recirculate and it works fine no issues.
So I replace the sand in my filter cause it's been atleast 8 years and the sand was really good. But I replaced anyway with new. I'm at a total lose here. Can someone help
