Zone three not going on. I have 8 zones and only 4 valves. Wire look good. My thinking is, if I have 8 zones and 4 valves they must be tandemed together. So whatever is wired with zone 3 is still working. I do think the solenoid and valve is good? being all other zones are working. What a PITA I …

Have you tried disconnecting the zone 3 when running to see if it makes a difference and/or tried moving zone 3 to another unused zone?

Hi, I moved the zone 3 wire and plugged it into the zone 1 push pin. And it still doesn’t work. And if I put zone 1 into zone 3 push pin, then 1 doesn’t work.:frowning:

Sounds like possibly a problem with zone 3 relay and maybe zone 3 value, wiring, or water
