[AT] Shop LP Plumbing

Nuther thing that hasn't been mentioned; I was told many years ago that
natural gas pipes should be in the walls & propane pipes come up thru
the floor.  Natural gas rises; propane heavier than air so less chance
of creating a bomb in the wall.  This was in the era of pier & beam
houses; don't know about slabs.  I saw examples of this; pier & beam
always had the pipes coming up out of the floor.  Sounds logical.

Not positive, but pretty sure that copper IS OK for LPG but NOT for
Natural gas.  As Chuck says, there is something in nat gas that attacks
cupper.  Sulphurous compounds??
