Oil fill black steel and galv

Mainiac2000 Member Posts: 1
Hello, I am piping the fill and vent for heating oil with 1 1/2 inch black steel pipe. Is it okay to use galvanized elbows and couplers? I ask because I have them already and I would save money. If there is any reason at all not to mix the two aside from aesthetics, I’ll just go by the black pipe fittings. Thanks

    Depends on where you are located and if it will be inspected.

    I did that once piping a 275 gallon tank in Connecticut and I had a bunch of galvanized elbows to use up with black pipe.

    The inspector made me rip it out and change it.

    I still see nothing wrong with it.

    Some black paint would solve the problem.
