I have a Fimco 6 zone indexing valve. I’ve replaced all of the parts in it, as I was having a problem with the zones sticking. Although everything is new in the valve, on occasion, the zones still stick, and will not move to the next zone.
When it does work, I have watched it move. I turn off the pump, and 30 seconds later, the Cam indicator moves to the next zone. I have noticed that this in conjunction with a sucking noise, and the wire on the other valve in my photo jerking back a bit.
So my questions are: What is the other valve in the picture (it’s the black valve on the left with the light blue cap, with a wire attached to it terminating at an an adapter on the PVC inlet pipe)? Do I need it? What is its function? Does the Fimco indexing valve need it? Does it have a vacuum function that is causing the Fimco zones to stick?
Thank you!
