Unless you have high water pressure, all the water will flow out the cut end. And even then, you'll get just a meager rise out of your sprinkler. The best bet is to cut the lines clean and cap them (I'm assuming you ran PVC). Caps are cheap, so two won't break the bank. The glue, if you have to buy it, will be a few bucks, but it's under $10.
When you cut the pipes, make sure you leave enough room after a sprinkler head "T" so in the future you can cut the cap off and expand the system if you need to.

Subject: [DIY] Identifying sprinkler circuit after tree removal destroyed some
We had a tree removed a few months back and the digging radius turned out to be far bigger than anticipated. There are two sprinkler circuits in the affected area though we're not sure which sprinkler heads were actually shredded (partially because I foolishly didn't map them out before the tree removal).
The sprinklers in the surrounding area are essentially unnecessary now since it was the end of the line and I was planning on capping off the line. However, I'm not sure how best to identify the sprinklers involved now.
If I turn on the sprinkler circuit, will it pressurize enough to pop up the heads so I can see where I need to dig? Or will it all flow out the destroyed pipe into the soil under that area (I'm guessing it's about a a foot deep).
This is all new to me, so hopefully I'm making this more complicated than necessary. Thanks for your input!
