Question
Hi Guillermo-

I have 2 zones on my sprinkler system that won't come on at all.  I have tried the following:

1.  re-stripped the wire ends (all the colored wires for each zone) and wired them back together with a new wire nut.
2.  check power to the valves.
3.  replaced the solenoid and the valves.
4.  swapped the wires at the clock to a zone that does come on.

Any thoughts on what else I can try?

Thanks-
Scott

Answer
Hi Scott,

The power at the valve should be at least 24 volts, if is less the solenoid will not open the valve. The water source is the same in all valves? If you have different sources make sure they all are open.

If you can feel the valve opening and the water flowing (slightly open the screw at the valve) water should come from the screw, check for possible obstructions after the valves.

Regards
Guillermo
