      when installing new hot and cold supply lines thru new tgi beams what is a good spacing distance side to side and from the bottom of the tgi up?I know from some experience that getting long lengths in is more difficult

      If you are drilling holes in them make sure you use thse inserts and I would make them 6 or 8″ apart so if you have to cut pipe you have room for cutters, dont run them less then 4″ apart.

      Inserts are pvc rings that fit into hole after you cutit, you put them on pipe and after pipe is in you push them into the hole, you dont have to use them but make sure you make hole big enough for pipe to expand and also hang it every 8′ at least 2-1/2″ from bottom of joist.
