I'm considering replacing my HW Tank (40 gal), but only if I can convert the rigid copper water lines and galvanized gas line to flexible. I was told by someone that flex lines are against code in Michigan. Does anyone know for sure if they are, and if so, why?
IPC 2006 and Michigan Plumbing Code 2006
I believe you MUST use flex lines in other states, like California, so how could it be AGAINST code in Michigan?
