    Pex to copper at sink
    I've always been curious as to why on a house that is entirely plumbed with pex they use the "L" shaped copper pieces at the location of sinks and toilets.

    I'll try attaching a picture as an example. Would a pex elbow and a short pice of pex tubing accompish the same thing?

    Also why is the copper piece sealed off on the end? I could put a plug in the end of the pex elbow and again accomplish the same thing if there are no rules or codes against such a set up. I guess if I have a shut off at the manifold I'm not sure why the end needs to be pugged anyway?

    Copper is still a much better product to attach angle stops to.

    Granted, they do make PEX angle stops, but there is no way to ensure the stub-out will come out of the wall looking right -- This is particularly important when installing angle stops that will be seen, such as water closets, wall hung lavatories or pedestal lavatories.

    I stopped using 'stub-out ells' about a year ago when it became too much of an effort to explain to the drywall hangers that the points on the end of the ells are not designed to be pushed through drywall -- Angle stops that flop around because the ell has broken free of the 'hold-rite' tend to tick the client off.

    I now stub out with soldered copper tubing that is backstopped with 2x4 blocking to ensure that I have a solid connection when installing angle stops.
