Rinsing line set?

[LeftyMetz]

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

Common?

[knave]

[hvac wiz 79]

how many ppl have actually been caught red handed venting into the atmosphere ?

[fearlessfurnace]

If he is running r12 through it after braze the oxide is still in the pipe.
r 12 he must be joking

[hvaccolo]

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.

[Hindermanhvac]

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
