Rain Bird RC-7Bi with K-Rain Indexing Valve: Zones Change on Manual Advance

4 Output Wires from Timer → 2 Wires to Indexing Valve

Indexing valve (K-Rain 4000) rotates mechanically with water pressure. Each pressure cycle advances to next outlet. Timer can't control individual zones.

Solution

Install 4 separate automatic valves, connect to the 4 indexing valve outlets. Allows independent zone control. Some Florida counties ban indexing valves and offer credits for removal.
