Sudden Pressure Loss Across All Zones After Valve Repair

After a repairman fixed a stuck solenoid on one Weathermatic zone, all zones lost pressure—only gurgling. Water meter didn't spin abnormally, ruling out major mainline leak. The system is 6 years old.

With no meter movement, a large leak is unlikely. The issue may be multiple valves stuck open simultaneously due to a wiring fault, controller malfunction, or crossed wires—exceeding supply capacity. Test by activating one zone and watching the meter: if it spins rapidly, only that zone runs. If it spins wildly, multiple zones are on. Check controller output voltages and field wiring for shorts. A master valve (if present) could also be stuck open.
