All Zones weep
This is an 11 zone system with I believe Buckner valves and a Hunter controller. This is in southern CA so freezing is never a problem. The system was off but pressurized for about 6 months. After turning on, all worked OK except zone 11 would not turn on. The solenoid appears to work OK, nothing stuck in the valve body. Then I noticed the pressure gauge downstream of the regulator showed zero pressure. Replaced the regulator with new and turned water on. Now all circuits weep water and cannot get pressure to hold in the system. Tried adjusting the regulator but no help problem still exists. Cut power to the controller, removed back up battery, still all circuits weep water and no pressure in the system. I'm baffled. Help please!
