Customer Question

Have a Hayward Pro Series High Rate Sand Filter.
I had managed to get it to filter but when I tried to backwash it wouldn't work.
I was told it was the spring in the Vari-Flo Valve so I replaced it.
Didn't resolve the problem.
No matter where I set the handle could not get it to work unless I turned the pump on and off multiple times.
When I was finally able to get it to filter yesterday it put a white foam out onto the pool surface. It hadn't done this before.
Could it be the pump?
Could it be sucking in air someplace?
Hope you can help.
