Galvanized pipe for the water with galvanized fittings, Not brass. Water running through these two unlike metals will cause electrolysis which eventually will cause rust from the galvanized iron pipes. Black iron for the gas.
Combustion is possible if oxygen is present, to stop combustion you need to cut the supply of oxygen. Sol'n: place it in a vacuum or chamber without any oxygen.
There should be dielectric nipples at the heater , if not that can cause some problems (electrolysis) , if the well pump or pressure switch is shorting or passing a small amount to ground it can shorten the life of your pipes drastically . I have replaced some galv. pipe that didn't last very long (about 6-8 months) . The supply house had gotten a batch that was from Mexico they replaced the bad stuff and I had to eat the labor but I kept my customer happy . The China pipe is worse about the galv. coating being to thin or of ?? quality (it too doesn't last very long) I have seen the welded seams not welded . The cost of copper has gotten ridiculess and so I now use Aqua PEX or Dura PEX for most of my water lines. I suspect this plumber may have lost a customer over this as you are asking .
