OK, he left about an hour ago. Looked at what I had and what was planned and said "That would've worked".

Anyway, he fitted a union and a T to run to the grill. The one big advantage he has is a box with nipples in what looked to be 1/4" increments. He'd be able to fit up any length very quickly.

He'll be back on Sat to finish plumbing the grill line....using copper.

Also, he did confirm the bushing as being "illegal".
Rick, the reduction bushing is as you describe.
