Gas pipe tightening question from a newbie
Frankly, I use a few unions. I think the pros don't do this for 2
reasons, experience has taught them how tight everything has to be, and
cost, unions cost $ couplers cost cents. A third reason is that they
use liberal amounts of dope, a forth would be tools, most people don't
own a 4' pipe wrench let alone 2 nice light aluminum ones.
