I need to replace the galvanized pipe in the house. Starting to get pin hole leaks on the hot and man, it is really corroded inside. Anyhow, I'm looking at the options for replacement. No copper so it's pex or PVC/CPVC. I know nothing about the Pex but watched some good video on YouTube about it. Looks like it would go in fast, lots of options for types of fittings. Anybody have any experience with it...opinions... recommendations? Jim? anybody?
