Rain Bird RC1260BI: Zones 2 and 5 Cycle but Deliver No Water

The timer shows zones 2 and 5 running, but no water comes out. The owner asks how to replace the valves.

Diagnosis

Since two zones failed simultaneously, a wiring issue is more likely than two valves failing at once. Check the field wires from the controller to the valves for cuts, disconnections, or corrosion.

Action

1. Inspect all wire connections at the valve box and controller.
2. Use a multimeter to verify 24 VAC reaches each valve solenoid when the zone is active.
3. Only if wiring is sound, rebuild or replace the valve (see irrigationtutorials.com for guidance).
