View Full Version : Slope + length + number of taps info needed

There is a large section of area that I am working with that can not have a main line on it. The main line that it uses runs up a steep slope parallel to it with the lat lines running out and up from it. Main line is 3/4". Some of the lat lines have 16 or more taps to them with some Y's and T's runnning to other trees. There is Im guessing a min of five of these lat lines running into main line. Basically the lines were already set up but rolled up on property line. Ive been working on rolling and setting them back up, and also adding to the lat lines with new taps and new lines. All is 5/16 line. All lat lines run somewhat down the slope which is pretty steep. Is there a calculation of the number of taps that a line can handle with an increased slope. Also what does the added number of T's and Y's add to the equation. With Y's and T's is there a certain amount that can be added to a lat line before a new lat from main line should be run. There are some areas where there are 3-5+ trees on a T or Y that run into the middle of lat line that has 10+ taps on it. Really need to work something out with landowner to put in main lines. Until then any info would be greatly appreciated. I plan on testing end of lats with vacc gauge but wont be able too till every thing is plumbed up. Thanks.

Sounds like one of my setups. I have upwards of 35 or so on it, on a steep slope into 1/2in mainline. theory on this is it creates a natural vacuum, believe it or not it works. line completeely loads up during the day run and in the am when you go out and check it its darn near empty. works well for me anyways

Is that 35 on one lat into the 1/2" main? Not sure if these being on vacc is going to make a difference. I know last year when the vacc motor was shot the sap would be trickling in through the releaser still. But this area was not plumbed in though. Im guessing the slope is prob 35-40% maybe 45% in places and maybe 30% in others. The lat lines dont run straight down hill, more like slighty sloping down and across.
