Moving parts do wear out. It may be time to replace the diaphragm.

Sure sounds like dirt in the extremely small opening under the solenoid.

You may still have dirt in the valves, in the narrow passages beneath the solenoids or in the valve bonnets.

Hunter PGV valve not opening after cleaning

I have a PGV valves in my 6yr old system. This spring, upon start-up, several zones began to bleed past the valve. I first tried to pull off the solenoids and open the bleed screws to flush the valves, however, the problem persisted. I then pull the valves apart and cleaned the valve, but still had valve leakage. As a last resort, (lawn was drying up) I purchased new valves and pirated the diaphram from the new valves. Everything worked for short period, however, some additional dirt got into 2 of the valves, and I again took the valves apart and cleaned out a single grain of sand. When i reassembled the valves, the zones will not pressure up. All other zones work fine, But the two zones I recleaned, will not allow pressure through. They are in different valve boxes and on different wiring. One zone by using the bleed screw, I can get normal pressure. On the other zone, I get enough pressure to pop sprinklers up, but only enough to spray half their area.



Any ideas/suggestions?
