Mainline Question

[wnybassman]

Good thread in the off season. I'll jump in with another question.... so if back pressure and minimal slope are a concern with the taps closest to the mainline that have little elevation drop on 3/16ths...would it be better to hook up any low elevation trees conventionally with 5/16ths into a separate mainline saddle and whatever you get gravity wise is more than not tapping them at all

thanks

That was actually my first plan, but then decided just to do the lower trees on their own 3/16ths line as well. I will only have a max of 6 or 7 trees on these lower lines, but the top most will still be 10-15 feet or more above the mainline so I guess I will still generate a little vacuum with these trees too.

Is there any minimum spacing for saddles on 3/4" mainline? I might have 4 or 5 in the last several feet of one of the ends.

I literally have 25 trees or so within arms length of the mainline so they may have only a foot or two drop

Last year i used 3/16 and 5/16 on a main line and straight in the tank both . I built a manifold using 2" pvc ,drilled holes to let the 3/16 into it and drilled and tapped with pipe threader for the mainline. It worked well and really like being able to see the sap running in,the mainline was black plastic and I am changing over some of it to blue mainline which I should see the sap running in also. Appreciate all the ideas on here !
