Our 5/16" plastic tubing is made at our corporate headquarters in Swanton, Vermont, giving us full control over quality of the pipe. Often called laterals, 5/16" plastic tubing is used to stretch from tree to tree, optimally connecting 1-5 taps, then entering a mainline.
Try to keep lateral lines less than 100 feet long, with as much slope as possible. Remember to "STRIVE FOR 5": 5 taps or less per lateral line, and 5% slope or greater.
