OK I'm sold I want to give 3/16" a try. Will be switching one area from 5/16" to the 3/16" We have really good slope in this particular spot however not an abundance of trees.

So the question is is there a set number of trees needed for 3/16" tubing to work?? This particular area would be about 15 taps.

Are you going to the tubing seminar at Bascoms this Friday? I bet it would be helpful. Experts there to answer questions. I bet 15 taps would be perfect.

Some good reading below. The bottom link is to Tim Wilmot's research on 3/16" tubing from 2014.

I read through a bunch of the 3/16 articles all of them sited above. (I suggest reading them, great material).

But yes, there is a minimum number of taps, I believe 4-7 was what was sited in the articles. With a maximum of 30ish. and no max or min in length. It's all about your elevation loss.
