Questions & Answers

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

Asked by: Sprinklerguy
Unfortunately, there are many things that could be causing your problem. It could be that your solenoid is bad and installing this, which includes a new solenoid could fix your problem. It could be a bad electric connection or wire to the solenoid. It could be a bad or faulty control system. Personally, I would start ensuring that your electric connections are working. This replace the solenoid, then replace the control unit in that order to try to solve the problem.

Max 150 psi. But what is optimal working psi for residential system? Should I connect before or after the PRV?

DIY install of first system...
Asked by: Freshmangreen
If you have a PRV already, I would install after that. Per the book, the ideal pressure is 30PSI. However, what I believe is nice about this system is you can use the knob to set a perfect PSI for your system and adjust it on the fly to be tailored to your needs.

What causes a backflow to another line

What causes a backflow to another line
Asked by: Janet
Because your sprinklers heads are outdoors and working in a muddy environment, when they shut off, some back pressure occurs and some sediment can slowly enter the sprinkler lines and over time force its way back into your main water supply. This device between the sprinkler system and the main water supply prevents that sediment from ever entering your main house water supply.

Can these be used with the orbit battery timer? Assume i would have to switch out the soleniod.

Asked by: Ccnj
From what I can tell, you can't switch out the solenoid without breaking it. There is a stop that prevents it from turning around fully to be replaced. You could break off the plastic stop to do it. However, electric solenoids are pretty standard devices and this likely will work fine with your system. You just need to make sure you have an electric connection in your system to turn the water on and off to all of your sprinkler stages. That assumes you are using one for all of your stages. If you are using one of each stage, then you should be able to connect your stage connection directly to this. That also gives you the ability to adjust pressure differently to each stage of your system.

1 in. FPT Anti-Siphon Valve with 3/4 in. Reducer is rated 4.2 out of 5 by 18.

The first one I installed was leaking at the black Solenoid on the top and there does not appear to be a way to remove it to fix it with Teflon tape or something. So I had to uninstall the system, return it to Home Depot, and get a new one. Once I installed the new one, it worked great. So my warning to you is to install it with screw on connectors so that you can easily remove it if you ever need to.

Tried to buy replacement diaphragm but you longer carry one for the valve that I bought several years ago. So had to buy the whole new unit…pain in the butt…and replace the whole thing.

I have had these valves for 5 or 6 years. The only they I would change is I would add a screen on the feed side to catch anything that might be in the lines from installing the system.

Rated 5 out of 5 by from Sprinkler valve I have a 6 zone system and have orbits on all but 2. I just replaced 1 of the last 2 left. All the other orbit valves are at least 8 years old and no problems or leaks. Definitely the right choice.
