I have a section of woods with a 15% grade, and around 130 taps, could I use 5/16" tubing to achieve a natural vacuum effect instead of 1/2" mainline for a gravity set up? I know some people use 3/16" tubing to get natural vacuum with 30-50 taps, but will it still work with 5/16" tubing and 130 taps? The longest section of tubing is about 140 ft to the tank. Thanks.
