    I need to remove a head from the end of a lateral line (poly). How do I do so without creating a dead-leg in the piping that won't get blown out during winterization?

    You don't. But you might be surprised how well a plugged poly line can endure. If in doubt, dig up the entire surplus line.

    Install an auto drain (King Drain)

    Remove head, go to next head in line, dig down, cut, cap.

    Leave the 20 or so feet of poly in the ground abandonded.

    Has anyone found a working auto drain thats older than 5 years?

    Yes I have. There are many systems here with them installed. They do occasionally fail, but so do the heads, valves, controllers and everything else. I used to hate them, and to some extent still do. But they do have their purpose and place. When ever I re-build a manifold because it froze and cracked, I install an auto drain because I don't want to dig up the box and do it again because they forgot about the mani drain.

    King now makes one for both lateral and mains - instead of carrying the opaque one for laterals and the red for mains.

    Not only do they fail regularly, they waste water. We install a quick couple on every project.

    This is assuming that the lateral line is sequential with the heads and not spurred off. Depending on how the laterals are piped you may be cutting off more heads. :)

    My bad Jon. I reread the question and it relates to poly. You plow boys always run in a stratight line. :p
