I love: "herd" of people, on SO many levels.

Yeah, I was pretty proud of that one as it came from my fingers, too. Sure
is appropriate for most scenarios.

I may tirade about anything other than black pipe but the next
leg we do will be in copper!

I've yet to see the joints leak when soldered, and it's faster and easier
than cutting threads. It's really a nice way to go, assuming you can
secure the quick connects such that they don't move about. It requires
very rigid terminations, but that's not difficult to accomplish. I faced
the same thing with my plastic pipe, which transitions to a short steel
nipple in either a tee or ell, also cast in concrete. My connects are
totally supported and rigid.


Quick math: 40 amps, 9600 watts, 9.6kw/hr
$.15/kwh = $1.44/hr
$1.44/hr * 70% duty= $1.008/hr cost for air. Lets say I'm wasting
$.40/hr.
$600 = 1500 hours payback. Compressors run 2000 hrs/yr. Leaks cost
$800/yr. Math sound fair if not conservative?

Gasp! And I whined when they raised our rates from .$0033 to $.0044/ kwh?

Yeah, the math looks fine to me, but then what the hell do I know? g

It would be real good to get the leaks under control. It's more involved
than just the money, too. Think of the extended life of the compressors.
Keep us informed, and good luck!
