    Rinsing line set?

    A bidding contractor- "flowing nitrogen is a pain. I just rinse with R12."

    Common?

    God, that must be expensive. And illegal too.
    Not as lean, not as mean, but I'm still a hardcore, ass-kicking, hard charging Marine! Oohrah!

    Some old timers used r11 to flush. There is a current product called rx11 flush that you can use that doesn't really contain any r11. That stuff is expensive and a pain to use...much more so than nitro. Don't use that contractor...he sounds like a bit of a hack if he told you nitro brazing is too hard.

    Still gotta use nitrogen to push the flushing agent through.

    Why not do it right once and be done?


    R-12, huh.

    WOW.

    actually I would contact the EPA and have them come out when the contractor is scheduled to then you get to earn half of his fine $$$$ LoL
