mainline question

[eagle lake sugar]

I'm planning a tubing installation for next year. It's about 2500' to the top of the ridge and about 800' wide. It's a mixed woodlot with around 1200 taps. Should I run one conductor line [wet/dry] in the middle with my mains running off that? The mains would be around 400' on each side. Or, should I run two conductors in parallel to shorten the length of the mains to around 200' each? Thanks in advance for any replies, Steve

I don't run vacuum but from what I've been reading I would go with the latter. I feel two conductor lines would allow better vacuum transfer. Just my two cents.

I think it all depends on how you want to do it. I would either A: run multiple mainlines say 3/4" maybe 4 or 5 or B: run 1" main across then 3/4" up the hill. Just keep in mind the recommended # of taps for the mainline sizes. Either way try to use as few fittings as possible.

Me I have two 1" inch mainlines running across the bottom of the hill sloping uphill of course with 3/4 inch branches running up the hill from there. So once my mainline was installed with all the fittings for the branch lines and tightened the branches were installed. I recommend buying the mainline by the spool and running it one line at a time and take the guess work out of measuring and at the same time through the use of saddles limit the amount of splices.

absolutely run one cunductor. You will need to size it. off the top of my head I would say 1 1/4 dry and inch wet. then for last 1000 ft run inch/inch. 400 ft mainlines is perfect make those all 3/4.

Your setup sounds ideal for a wet/dry 2-pipe system. Run the wet/dry lines straight up the middle of the hill and then run 3/4" mainlines parallel to the slope off each side with another mainline every 100ft as you go up the hill. It may cost a bit more to set up but you'll get high yield!

Thanks guys, that's kind of what I thought, but wanted to hear from some more experienced producers.
