Jar Top Automatic Sprinkler Valves

I like the ease of removing the top but it seems to me that an obvious design flaw exists as I have had two valves now fail in the exact same way. With the valves leaking past the obvious solution was the diaphragm. Wrong! New diaphragms and no change. Changing the O-ring. Nope. Maybe the spring is too weak? Wrong again. The amount of time spent troubleshooting should be billed to you to find a small crack in the valve body in the exact same place on both valves. Having 10 of them it just makes me wonder if I should start replacing them with another brand knowing what is coming. Oh, and I had them about 2 years.

Worked great

Very helpful customer service. I had misplaced the springs over winter after winterizing the system. You can buy everything except the springs to repair the unit (selinoid and diaphragms). Customer service was able to come up with a solution quickly.

I like the easy access to the diaphragm

I have 12 jar top valves in my lawn manifold, and 4 in my garden manifold. All, of which I control from an Orbit 16 station controller and operate them from my cell phone. I do occasionally have to clean or replace a diaphragm, but they are readily available at Home Depot and Lowe’s, who keep them in stock and at a reasonable price. I am very pleased with jar type valves as a very easy to maintain with an oil filter wrench, which fits them perfectly for maintenance. I do wish the diaphragm would provide a better seal as I have to tighten outer ring very tightly to prevent them leaking slightly at times. I have them mounted inside my garden shed on the wall, which makes it very easy to maintain them.
