Customer Questions & Answers

My orbit system doesn't come on with my timer could this be the problem

Asked by: Sprinklerguy
Sprinklerguy, there are several reasons why this might be happening. The cheapest and easiest thing to try first is to see if the flow control knob has the valves closed: Turn the flow control handle on the valve as far as it will go counter clock-wise, then turn the valve on. Next would be to use a voltmeter to determine if your timer is outputting voltage (confirming that the timer is functioning normally): When zone 1 is “on,” put the voltmeter to measure AC voltage and put one probe on the common “C” and the other on Zone “1,” You should read 23 to 26 volts. Next to make sure the voltage is being received at the valves to confirm the wires have not been cut somehow. You could use a voltmeter again, but if you do not have a volt meter, turn off the water pressure to your system and remove the solenoid from the lid of the valve and confirm that the solenoid piston moves in and out as you turn the valve on and off electrically. If the solenoid piston for zone 1 does not move in and out as the zone is turned on and off, but you know that the voltage is being delivered through the wires, you could have a bad solenoid or corroded connection between the sprinkler wires and solenoid wires. If you have only one bad valve on a manifold of 2 or more valves, you can swap solenoids or valve lids to see if the issue follows the solenoid or lid. That would help narrow down the scope of the problem. If none of the above attempts have not resolved the issue, please give our Support team a call at 1-800-488-6156. We'd be more than happy to help in any way we can, so your sprinkler system works properly. Thanks!

Rated 4 out of 5 by from Dont let this freeze I had to replace one of the valves on my sprinkler system because I forgot to totally drain the system last Fall. It was my fault and not of the valve. I have had my sprinkler system for almost 10 years with three of these valves and not problems. They work well in conjunction with my controller. I was very happy to find that this valve is still being sold at HD, and I was able to get an exact match. It took about 10 minutes to replace and I'm back in business. Just don't let them freeze.
