- Sprinkler Solenoid 24VAC Woes
- ailing 30 year old underground wiring, failing solenoid valves and their solenoids. Some of the old solenoid valves were replaced as they had mechanically ... outstanding problem was the just failing valve solenoids. Interesting only the new valve solenoids were failing. The 30 year old valve solenoids and the pump contactor continued working without problems. I tried 3 different new solenoid valve types and all the solenoids failed, within a week to 6 months. I have... ctor? That being said the valve supplier kindly sent me 4 replacement solenoids. I reached out to Open Sprinkler about the
