I have a gas line running to my outdoor hot tub water heater. When I
first installed it 8 years ago I used black iron pipe because i heard

Lately I've noticed that it is heavily rusted where it is lying on the
concrete.
Can I replace it with galvanized?
I get all sorts of answers from google.

IIRC it depends on the sulphur content of the natgas in your area . Have
you considered blocking it up off the concrete so it's not in constant
contact with the moisture that's causing the rust ?
