when to put up tubing for 2012

[Maple Hobo]

I bought my 3/4" Black Waterpipe for Tractor Supply. they come in 400' rolls. I got it for $80 I beleive it was per 400'

If your running a high vac system the typical black water pipe is softer and can collapse under vacuum.

I've seen a weak spot (slight kink) on the maple line collapse under high vacuum.


I vote not to put out new line untill its cooler, or they will pull appart in winter.
Install too cold and they will sag too much in summer and more critters can chew on it.
