Re: Out of round PVC
I wasn't present when this happend, but know it to be factual:
A roofer retro-fitting PVC pipes in place of galvanized sheet-metal
rectangular lines that drained flat rooftops, and which had corroded
beyond repair, used a hair blow-dryer to soften the PVC to make it
conform to the desired shape. He got a whiff of the fumes and very
nearly passed out; a bad scene, all the way around. Bear in mind that,
here, stateside, PVC is *not* approved for use in homes, for the hot
water line. CPVC is. "Hot" water here might be anywhere from ~120F
on up, but typically should not exceed maybe 135F. My point is: that
heating up PVC can result in dangerous fumes, and that PVC might
be pliable <and generate dangerous gasses> at lower temperatures than one
might think.
I'd guess that it might be easier to locate some other, more suitable
form than to try to right what you have...
Regards,
Randy
