Hello, I just installed a 3050 and a fns60. I keep getting air in my pump's hair/lent basket after several hours of running on 2100 rpm. I did have a pool company come out and give me a pressure test, He said no leaks. My pool was green with algae, He suggested my filter was back pressuring into the pump. Now my water is crystal clear and still have small bubbles that turn into an inch and bigger in the basket. Here is the kicker, when I shut the valve to the pool off and go to the spa the bubbles are sucked out, but will reappear after some time.
The pumps owners manual says something about a check valve if I have a booster pump in series. I do have a booster pump for the spa, it looks like it goes directly to the spa to the booster, no filtering. When I turn on the spa function and the intelliflo is on I can hear air type noise from the blower. I replaced a hayward 2.5 hp pump and the glass was so fogged up in the basket I do not know if this has been going on forever or if its something to do with this new pump system.
any help or ideas are appreciated.
