    I also here that propress isn't good for application that are subject to constant vibrations. A voper compression system seems like the worst place to try to use propress.

    You are referring to what's known as a "coaxial fitting". As hvacguy said, if you have very hard water in your area they will get clogged up easily.

    I know, but time is money and I like to be lazy and let the instrements do the thinking. I do think one should have the ability to "rough it" in case his fancy meters fail though.
