Zone 6 Dead After Pipe Repair: Check Valve Power, Not Just Pipes

Trench Work Killed Zone 6: Likely Wire Damage, Not Pipe Blockage

Homeowner broke pipes before zones 5 & 6 while trenching. Repaired pipes, cleaned debris, left ends exposed overnight. Now zone 6: no water, no hiss. No geyser = no new leak. Suspects vapor lock.

Overlooked: Electrical Damage

Trenching likely cut or nicked the valve wires for zone 6. The valve isn't getting the "on" signal.

Diagnose: Check Solenoid Power

1. Turn on station 6 at controller.
2. Carefully unscrew the solenoid (wire-connected cylinder on valve).
3. Feel/hear for click or plunger movement.
4. Click = power OK → problem is hydraulic (debris, valve).
5. No click = no power → trace/repair wires from controller.

Don't assume pipes—check the wire first.
