Review: Replacement for older Rain Bird valves with some modification - I have old Rain Bird valves on my irrigation system which has a different solenoid than the new versions and I couldn't find any old style anywhere. Thanks to a comment in another review, I was able to utilize this solenoid on my valves. As the other review stated, you have to use a knife to cut off the white plastic at the end which retains the solenoid core then it works fine for the Rain Bird. Worked so good, I bought two more to replace all the solenoids while I could get them. Saved me from having to dig up my entire valve box and re-plumb everything. Review: This worked on my ancient Rain Bird valve - 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.

The broken one (prob 20 years old) was made in the usa, but the replacement that I bought from ACE was made in mexico. I'd imagine this one was also made in mexico. **Q: How do I tell if it is bad?** A: if you have 24v at the solenoid, and it does not open the valve the solenoid is bad **Q: how wide are the threads? I need a 3/4 inch diameter** A: Rain Bird makes a replacement solenoid that is a 3/4" male thread. **Q: Are these waterproof or do they need a cover? My old solenoid had a thread on top that held a cover on.** A: I wouldn't say waterproof, but mine were exposed and got wet often, but they lasted a long time before needing to be replaced. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Replacement for older Rain Bird valves with some modification *by J***N on January 19, 2026* I have old Rain Bird valves on my irrigation system which has a different solenoid than the new versions and I couldn't find any old style anywhere.
