    If the deal on a house we made an offer on goes thru, we will need to repipe it. It has polybutylene tubing in it now.
    I think we will have Pex put in. The pipes gos up into the attic and down to the fixtures. They will all be insulated.
    Just wondering if there are any things I should ask for? Should the Pex come all the way out of the walls, or should it switch to copper there?
    Any other thing I should ask? Are there different quality Pex tubings?
    It's not going to be a manifold system, as in there now.
    Thanks for any info.

    With PEX you have options.
    You can make the arguement for copper at the stops, or not. And using a manifold is fine.
    I have been using Uponor, but there are other brands that are good too. They use their own ways of making joints. For Uponor, I have a handheld expander that runs on battery. So what flag will you have in the front yard?

    If it has a PB manifold system, I have never heard of them needing replacement or even repairs. Running PEX directly to the stops at the fixtures can create problems. I prefer the preformed copper stub outs. They are easier to secure in the wall, and more reliable.
