Review: Great - Works great
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.

## Questions & Answers

**Q: Are these solenoids made in mexico or usa? i ask, because the threads are different.**
A: i recently replaced one that was broken on my system.  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.

### ⭐⭐⭐⭐⭐ Seems OK after all
*by K***T on 29 May 2023*

I first thought this was incompatable but now concluded I won't know until I can test it in real life I have now tested it and it seems to work fine without leaks. So although it does not look exactly the same as my original Richdel it does the job for me.
