I guess I should just keep my mouth shut. As a plumber and gasfitter for over three decades I have become accustomed to using our terminology which, apparently, isn't global. In the hundreds of miles of steel pipe that I have installed, I have never tapped a pipe with threads. Now, branches off of water mains are a different thing, but those threads are nothing like the threads we are talking about here.
I was just being a smartass when I quoted youroo and I meant no offense.
