Not that I know of. Recent research on vacuum systems has been on bigger lateral lines - 1/2". It is supposed to avoid the slugs of sap/ice in the lines and get better vacuum to the taphole. I can't imagine 3/16" allowing more vacuum to the taphole and would in fact expect it to be much less.Originally Posted by Little Maple

I think I heard somebody say they tried it on vacuum and that it worked good but maybe they had really good slope or the small tubing allowed the sap to be pulled through the tubing and creating a vacuum on the other side. But I really don't have a clue.
Steve J, I have no main line because that's all the trees I want to tap on that hillside. About 20 taps on a 500' run (three of them). It's only about a 2 acre area. If I had about 5 acres or more I would want to use a main line. When the sap dumps into a main line you no longer have vacuum. Maybe UV Proctor will be testing check valves on these. I bought more CDL clear "Y" spouts for next season.

One more question I do have a main line in place at bottom of hill side with fittings for the 5/16th lines. Can the 3/16th line be adapted to fit to this or must I buy new fittings?

You will probably need the 1/4 X 5/16 adapter that is used on the tap end. A short piece of 5/16 will connect to the mainline.

I went to Mcmaster Carr and it appeared to be a plumbing company? and looking online at DG I did not see the 3/16s listed but they have a rather poor website.

If you e-mail D&G in Vermont, they have 3/16 tubing. It's $45 per 1000 foot roll.
Well I ordered enough fittings to do 60 taps and if it all goes together well will order another 60. I going up to DG one day this week to buy tubing and to see if they can give me an idea what tubing tool to buy and how to modify it as I never used such a tool in the past.

I went to see a 3/16 set up being built this last week at art krugers. he got a grant from state of vt working lands to fund the project.The tees came from McMaster Carr. Not d and g . The drops are 5/16 . Was told maple co.s are not successfully making spouts , or connecters at this time. what he is doing is taking a short piece of 3/16 pushing on top of tee then pushing the 5/16 drop line over that. then cut drop in 3/16 line. the lines are very long. he took all his mainlines down. i did not see a main line connecter. he did have vac gauges at the top of every line. he put up 200 taps last season and liked the way it worked. sold his vac pump and is going 100% . will go back in spring if i find time to see it work

I have another question from what I read it appears that at the head of each line a vacuum gauge should be installed. I have never worked with such a gauge they seem to be inexpensive from Granger. My question is are you putting one on every line or is there a way to have a test port that you can plug on every line?
