Hopefully a quick question for someone with more experience than I have with home irrigation systems. I did google around first and didn’t find my answer.
This auto drain is leaking(brand: king innovation). When messing with it I found that it’s installed on the pressurized line that feeds the valve box in the backyard. I didn’t think these would be installed on a line that’s pressurized pretty much all summer long. Is that a correct thing to do?
If that’s an okay thing to do then I’m assuming this part has just failed and needs replacement. If that’s not an okay thing to do can I just unscrew this drain and cap it off instead? I open the valves and blow it out by zone prior to winter.
They are typical as low-point drains and manifold drains, both on the main line (always charged). Don’t just cap it if that would make a dead end, especially if it’s sloped down to drain. I can’t tell very well from the picture, but if it’s on a tee you would be okay putting in a threaded cap.
