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.

1 in. FPT Anti-Siphon Valve with 3/4 in. Reducer is rated 4.1 out of 5 by 35.

No need to remove the lower part of the existing pipe connections--just remove the screws from the new part and unscrew the vacuum breaker nut. And install these new parts in the old valve body and connect the 2 wires to get working again without any digging or actual plumber work.

The leak was where the solenoid screws in. There is no O-ring or gasket so I wonder if any of the other valves will start leaking over time. This could use a redesign. Once I replaced the leaking valve, all valves are opening and closing properly with the timer.

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.
