I had a plumber install a underground gas line for an outdoor
fireplace. He installed a shut-off by the house, and used a properly
coated gas pipe. What concerns me is the galvanized fittings were not
treated in any way.
My mason is ready to pour a slab over the line, and now I'm freaking
out about the fittings rusting and leaking. The plumber turned out to
be a flake, and is nowhere to be found.
Should I have the line dug up, and have the fittings treated?
Will they last if left untreated?
How do I treat the fittings?
What is there danger of an eventual leak?
