Just to let everyone I am new to this site but not new to Hondas . Also I am married with a kid on the way so I have to be cheap , hence the reasoning for this post . I work at a major hardware store and my brother works at the largest supplier of PVC pipe in the US . I have been looking at using schedule 40 PVC as IC piping . I figure if it doesnt work I am out 20 bucks but if it does i save about 150.00 , i just wanted to read some opinions on this . Also has anyone ever tried this b4 . It seems to me that it will work. I have a friend who used to be an airplane mechanic and is extremely smart and he believes it will work . Just any comments anyone has post them . If you dont think it will work explain why not . The temperature ranges will be fine since that is the first mis conception that it will melt . Anyways , post away .
