yeah, ill put it this way, all i got is a half inch to maybe an inch for diameter of a line that i can run up to the attic.
That being the case, and since i have to snake the line down through the walls, etc, it has to be flexible... and thus plastic.
I understand what you guys are saying about heat, but if i put a long enough hard pipe prior to going plastic, ill be fine, im not worried about that.
What i am trying to figure out is the best way to pump the air up.
notice i didnt say fan because with a half to an inch line, no fan is going to move air through 50-75 ft of half inch line. Thus i need a pump. I was thinknig about using a hottub pump, but have never had any experience with them before.
