    2 issues. I live in Florida. We have a concrete slab as our foundation. In our garage the water enters the home from the slab into a PEX manifold.
    One of the lines coming off the manifold looks corroded of sorts. It’s a line that is used daily- as it runs to the kids bath.

    Question #1
    1) What is happening with it and how do I correct the issue?

    The second issue (I think or perhaps it’s related to the first issue) is recently I have noticed what appears to be mold growing on either side of the wall surrounding where the water enters the home from the slab and runs up into the wall to connect to the manifold.

    Question #2
    2) What could the cause of the moisture most likely be? Could the lone be split where it exits the slab? Or is it leaking where it connects to the manifold? Or perhaps it’s related to the first issue and the simplest fix is to reconnect the line to the kids bath and see if that solves the issue?

    Any professional help would be appreciated.

    Thank you.

    I would assume there is a leak behind the drywall. I would cut that open and have a look

    Also, regardless of what you find behind the drywall and baseboard, that mold has to be attended to, as you probably already know.

    As far as that one pipeline connection, with what appears to be hard water residue, I would suspect a water seepage. I would clean it up and watch and feel for water seepage frequently. It could be just an occasional drop that evaporates and leaves those deposits.
