Last night, I noticed that the return flow was somewhat diminished, so I decided to backwash my 200# Hayward sand filter with spider valve (my pressure gauge is broken and I haven't replaced it yet ). I set the valve to BACKWASH, turned on the pump, and nothing happened. I then set the valve to RINSE just to see if it would start flowing and it did. I was running out of daylight at this point so I came back to it this morning.
Now, I can't get any flow with the valve placed in the BACKWASH, FILTER, or RINSE locations. I get good flow with it in RECIRCULATE, though, which leads me to believe this is a filter or valve issue. Does anybody have any ideas where I need to start looking?
