Sprinkler System Dead After Wire Repair: Check Master Valve & Main Shutoffs

System worked after wire repair, now nothing — not even manual bleed. Check:

1. All main valves open (curb, backflow, irrigation main).
2. Master valve? Check controller wiring for MV terminal wire.
3. If MV wired, it must open for any zone to run.

Recent house water shutoff may have left irrigation main closed.
