All,
After letting my system bake for almost 2 weeks. I found that I'm still getting air into my system. When I bleed the air out the system works fine. Looks like I will need to add some sort of air release.
I finally bought a kit and replaced the bonnet, diaphragm and solenoid. I also changed out my fountain head to one that restricts more than the last one. So far it's been working for 2 days. Looks Like I had 2 issues pressure and bad/legacy solenoid.
I will keep you guys posted. Thanks for all your help.
I had this same problem myself on an old 711 valve. I stripped the threads on a brand new solenoid. It was definitely too long. I thought I just took the retainer off a new solenoid but maybe I installed the old style solenoid. They have redesigned it where the plunger is much bigger.
I bought just the solenoid, the guy at the counter said this is the one. The box description said for irritrol. I'm not sure if I removed the other o-ring which sits in the spot where you screw in the solenoid.
The part of the solenoid that screws into the valve is much longer than the original. Thanks for the tip, I will try installing without the o-ring. I will try that today and report back and post pictures of both solenoids.
Then you're doing something wrong or have the entirely wrong selonoid. The replacement would be an Irritrol 216B. Which would use the exact same selonoid.
Are you removing the o-ring? The new selonoid has an o-ring built in, so make sure you aren't doubling up on o-rings.
Did you purchase the selonoid only, or did you pull it off of a valve?
I tried that it didn't work. The shaft, the threads are on is too long. The original solenoid threaded shaft is half the length.
So if you put both solenoids side by side the tip where the threads are, the original is about 50% shorter if that makes sense. I will post a picture of both when I get home.
