Faulty sprinklers

16 years ago

My sprinkler system (toro valves) has 8 zones. everything operates normally up to zone 5. When zone five finishes and zone 6 comes on, zone 5 fails to shut off. When zone 6 shuts off so will zone 5 leaving zones 7 and 8 to operate normally. Any suggestions on what will cause this problem? The system was installed in 1997.

Additionally, how do I identify the type of toro valve that I have? I suspect they are Flo pro type valves but how do I determine the specific type?

After reading some other posts I suspect the valve diaphragms are failing (zone 5) I also found out the valves I have are no longer made (flo pro 2800514). Will another model Flo pro valve diaphragm work? Or do I have to replace the valve manifold?
