Capping or removing a sprinkler is done differently depending on whether or not you live in an area that freezes and requires the irrigation system to be winterized. Winterizing your irrigation system involves draining or blowing the water out of the system with compressed air to prevent freeze damage.
If the sprinkler you want to remove is the last one on the pipe, you will need to locate the sprinkler that is “upstream” (closer to the source of water from the sprinkler you want to remove), cut and cap off the pipe there. Capping the pipe at the upstream sprinkler prevents a “dead end” of pipe that would fill with water but not have any outlet. During winterization, the water could get trapped in the “dead end” and potentially freeze, breaking the pipe.
Note: Teflon tape is recommended when using a threaded cap.
|If temporary shutoff is all that's necessary, a shutoff cap could be used on Hunter Pro Spray model pop-ups.||
