My sisters house needs re plumbed. Very small house with a deep crawl space (about 4 ish feet). We're in Iowa, so it gets cold. Its well insulted down there and she's never had frozen pipes. That being said she's got old CPVC lines down there that look like they've seen better days so she wants it all replaced. She's on a very tight budget so I suggested PEX for ease and cost.
I've only used brass with the occasional plastic fittings... which one is better for a potential freeze? Like I said it probably will never happen but just in case. I know she can save a lot with plastic so that's attractive. Not sure of our PH level (not in our water report) but the town that connects to ours is above 7, so assuming it's hovering around 7.
Outside of that.. stupid question.. should insulate all the runs of PEX down there?
