The question is - Black pipe or soldered copper. Black pipe is rather a
pain to work with, heavy and fairly expensive, while type L copper is
much easier to work with

Did iron in the last shop, pia and leaky[I know shudup]

copper in this one, 3/4 sloped to compressor, 1/2 drops with a ball
valve at every junction. 160 feet of 3/4 and maybe 60 feet of half, tees
l's and whatnot, what could it have cost? Don't remember, will last
longer than me

I bought a hf ref dryer ~2 years ago and it works great.
