How fliexible is 3/4" mainline ? Using as line for dump stations and no wire

[smokeyamber]

I checked on this before and most advised to use 3/4 line for dump stations, as I get closer to buying the tubing I was wondering how flexible this stuff is. My plan is to string it up loosely and if needed walk the lines to make sure it drains aftereach collection. One end will be connected to a 5 gallon bucket and other will feed into my 200gallon tank at the bottom of my steep hill. I will also likely have 2 possibly three lines t-ed into one main line with buckets as well. This setup will take alot of walking with 5 gallon pails down the hill out of my day while still letting me use my buckets which I really like.

Is there a type of line that lays straigher than others ? I am likely getting my stuff from Goodrich's.

Thanks for any input on this in-between use of tubing ;)

get some kelums grips, mainline grips bascoms sells them as, and use them to put some tension on the line then just support it a few places in between and it will work well, doesnt have to be pitched smooth like mainline does. i have a 1 inch poly line about 70 ft long that i have hanging this way, with no supports in between, its how i dump from my truck tank to the sugarhouse tanks from a hill nearby, only about 2 ft of pitch on the whole line, and when full of sap it stretches and sags alot in the middle but then drains itself out from the vac created by the flowing sap and springs back up to where it was

Perfect ! Thanks for the info I will be getting the line soon and the stretchers!

Those grips go by many names, Pipe grips, chinese fingers and a few others. Most dealers carry them. I use them for both my 3/4 and 1" mains. I use one at each end of the line, my lines are fron 580' of 3/4" to 1000' of 3/4 then connect to 200' of 1". I anchor them at one end with high tensile wire around a tree, at the other end I pull as tight as I can by hand and then connect a 1000# hand winch. I pull that quite tight and anchor that end. Then I add side ties to tension more. I generally do not have any place along the length with more than 25-30' unsupported, usually by a side tie to a tree. If you have a 2% or greater slope you should have no pockets catching sap. At the high end run the tubing up thru the pull loop and at the low end go down thru that loop. The grip does not need to be right at the end, you can devise a way to run it as long as you have no sags to catch and hold sap. Walking the sap down to drain like a hose might not work if you run it with sags, it likely would require too many trips up and down to get 100%. Even if you try that with a garden hose with the inlet end loose to allow air, you must move too slowly to be sure to remove 100% in 1 trip.

Is the puller a come-along type thing ? I can see using that or is it something like a fence stretcher ( which I haven't used ). My drops will all be 3/4 likely since I figure a 3/4 line will drain my dumpbuckets fast enough. Getting closer... time to walk and measure my runs, should have done it before this snow headed our way. At least I got some dry wood split and stacked ... worse case I will be doing spring exercise regimen, lost 10lbs last year hauling those killer buckets.

Thanks again for all the imput, I will post my results for any who might try this as well...
