I live in Tampa, Florida and have a natural gas water heater. It is plumbed using galvanized pipe through the attic to a couple of galvanized 90 elbows and a short nipple to a brass gas cock and short length of soft copper to the heater.
I thought that code prohibited or discouraged mixing materials in gas lines. For example, if a line starts out galvanized, you shouldn't mix galvanized and brass tees and elbows, etc.
Galvanized gas cocks are pretty rare in our area and brass are the norm. Also, I personally think brass unions seal better than galvanized unions.
So here's the question:
Is it acceptable to use brass gas cocks and unions in an otherwise all galvanized gas line? Again, the line I am talking about is all above ground - either in the attic or exposed on the garage wall.
I would appreciate any clarification.
Thanks!
