Just curious if anybody has anything special that they do when sleeving a main-line pipe with fittings and other lines coming off of it along the way? I've got about 120ft of main line that I need to install that will eventually be buried underneath a concrete slab. I've got about 4 tees along the way to install with smaller branch lines coming off of that for sprinklers. I was just going to sleeve the main line up until where I need a tee, install the tee and branch line, then butt up the sleeve to the other side of the tee leaving an opening around tee, and repeat that all the way down the line. It sounds kind of odd to sleeve it in the first place because how am I supposed to pull the main line out in the future if there's a problem without finding a way to cut all if the branch lines, but it's not my call. Any suggestions, or does that sound like the right way to go about it?
