    Couple questions about converting copper to PEX
    Hello,
    I have city water with good pressure that comes in off the street in a 1/2" copper line.
    I am going to install a Manabloc Manifold and have a couple questons.

    1. Can I use a copper to PEX coupling where my water enters my house (after the stop valve and meter of course)?
    2. If so and since the manabloc inlet is 1" should I use a 1/2" copper to 1" Pex coupling and then run the 1" PEX to a Tee feeding hot water heater, and Manabloc manifold, or just run the 1/2" PEX to hot water heater and manifold?


    Thank you,
    Mike

    You should immediately upsize from the 1/2" copper water service pipe to the 1" PEX.

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...
