Hello everyone, I am going to be setting up tubing this next season and I want to start getting parts bough and on hand. I am using a shurflo pump with a manifold, I've been told to use 5/16" tubing, my first question is can I run 5/16" all the way from the first tap to the collection tank? I thought I read somewhere that on the smaller scale vacuum setups, your lateral line would work as your main line? I'm thinking between 100-150' for each length, and would splice in 20-25 taps per line. One other question, how many taps would you recommend on a 4.0GPH pump? Thanks for your help.
