Rinsing line set?

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

Common?

Lefty

God, that must be expensive. And illegal too.

NOT COMMON.... HE'S ASKING FOR A BIG FINE???????

I usually rinse it with water. :CU::patriot:

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

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

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.

:ditto: add i little dish soap to get it shiny clean.......:yes:

Still gotta use nitrogen to push the flushing agent through.

Why not do it right once and be done?


R-12, huh.

WOW.

I really thought it was a joke. YIKES!!!!
