First thing to do is fix the leak, you asshole.

Who said it leaked?

It was empty a year or so ago, and prior to that, it hadn't been run for a few years, because the compressor "wouldn't start"...

--he posted as much at that time...

Mabee he wanted to improve the efficiency of the system???

Yeah sure thing, pal....

Or mabee, like me, he relocated the unit and needed to empty it in order to make the move.

He couldn't figure out how to pump it down even if his life depended on it.

Now that it is all sealed up and evacuated he's wondering, "do I, or don't I??"

So you really think the cheapskate owns a vacuum pump and also knows how to braze ?

--because if he did, he wouldn't be asking about r22 substitutes in the first place...

It's a *leaker*, and currently, it's inoperable because the LP safety has (again) tripped.

Guaranteed.

OK - I did not receive the first post, indicating it was low on gas.
I actually CHANGED my compressor unit - using the old one to draw the
new one down, after removing the original R20 from the old system
using the new compressor and an old (pre-anti-fill-valve) R20 tank to
hold the old gas. Had my nephew come and gas it up with some fresh R20
when I was all done. I had done the "draw down" test - he pressure
tested with Nitrogen to be sure "the old goat" had gotten it tight
before drawing it down again and doing the fill.

That SilPhos 15 rod works a lot easier than solder!!!. Self fluxing on
copper, and it just flows like honey!!
