I've seen how badly steel and copper pipes sweat in hot and humid weather, but I have not seem enough PEX to know how badly it sweats. Does anyone know if PEX or CPVC (and other plastics) will sweat as much? I'm guessing that it will sweat, but how much in comparison to metal pipe?
I'm asking this because I want to install some pipe inside my living space, because they are regularly freezing in the crawl space, and running heat tapes is costly on the electric bill, not to mention a pain in the ass to check in cold weather.
I'm considering using PEX or CPVC for this job. Most of these pipes will be going thru an interior wall, but a few feet will be exposed (and covered with some sort of wooden trim). But I dont want water dripping indoors that will cause damage.
Yes, I will cover the pipes with foam insulation, which I know helps a lot with sweating, but is not 100% preventive.
Thanks!
