Flare Pipe
Is a dielectric union a concern for a natural gas fitting?
I am installing a new natural gas water heater in my home. The existing gas line to the old heater is black pipe to rigid copper pipe to a short piece of flexible copper tubing terminated in a 1/2" flared connector. Can 1/2 ' black pipe from the new water heater be connected directly to the copper flex tube or should there be a dielectric union separating the 2 disimilar metals? Would it be better to remove all the copper pipe and tubing and just install black pipe all the way to the water heater?
A dielectric union is not an acceptable gas fitting.
Me personally? I'd go black pipe all the way with a stainless flexible appliance connector (with shut off valve) at the gas valve.
G'luck!
PS (nothing wrong with the copper though)
