Irritrol R811-24VACG Replacement Solenoid

Would buy again.Be sure to remove white plastic piece at the end.

Nice part it works perfect.

Works just like an original. No issues.

4/5 for now because it appears to be a perfect fit and works. 5th star reserved for ‘will it last’. Easy to install.

Ordered this solenoid because it was the correct part number for an older solenoid that had gone bad on a fairly old valve. Popped the new one on and once I turned the water on the zone wouldn’t close even after turning it off on the controller. Turns out the white plastic piece on the solenoid would not allow the metal cylinder to drop low enough to close the valve. I removed the plastic piece and no issues. I saw someone wrote this in another review and thought I’d reiterate it to save any aggravation to anyone else. If your valve is older you may have to do this.

My sprinkler system uses 35 year old Rain Bird valves. These have been ultra reliable, but the solenoids have now disintegrated. They don't sell replacement parts anymore (bad Rain Bird). Modern Rain Bird solenoids don't fit. This solenoid worked in my system. For it to work, I had to cut off the white plastic that protrudes from the bottom of the solenoid, and remove the o-ring left over from the Rain Bird solenoid. Then, it was just a matter of screwing the solenoid in and attaching the wires. This easy repair saved me from having to dig up my valves and do a gigantic plumbing project. Amazing!

Easy to install and saved me a bunch. I did some trouble shooting myself since the sprinkler service company wanted $150 just to troubleshoot and then the same plus parts to fix. Very easy to change out since it just unscrews and two wires. So easy a Cave man can do it! Just don't forget to turn off the water to the system or you are going to get wet.

Normally sprinkler repair is a pain. Everybody knows it. This time I had a zone that didn't come on. After swapping things around in the box, I determined I needed a new solenoid. I ordered and an hour after it arrived in started the replacement. Not 5 minutes later the zone was working. Woo Hoo. Easiest repair ever. Usually, it's a days long ordeal.
