Long airline from Vacuum Pump to Releaser?
I was wondering if anyone has ever made a really long airline from their vacuum pump to releaser and how it worked out? My releaser will be about 2500 feet from the vacuum pump and will be hooked up to about 1000 trees. Planning on using a vacuum pump that does about 35cfm. From what I've read from the tubing notebook this wouldn't work unless I had a huge mainline. It's hard for me to believe this since right now I have just a 1/2 inch airline 800 feet to 300 taps and I get 26 inches of vacuum on the lines no problem. I plan on using 1.5 inch line next year.
I would like to hear what size airlines lines others are using and how long your airlines are to how many trees.
Thanks
