Orbit Valve Won't Open: Check Wiring & Timer Voltage

New valve + timer, 1 zone, won't open. Valve must be in CLOSED position (bleed screw tight). Likely wiring issue.

Test

  1. Verify all wire connections tight.
  2. At timer: run zone, measure zone terminal to common → 24 VAC?
  3. If yes → valve/solenoid issue.
  4. If no → timer or wiring fault.
