My dad's house (now sold) has a gas water heater. The gas water heater is plumbed to the gas line with black pipe coming out of the gas valve about a foot off the floor. This horizontal gas pipe runs another 2.5 feet where it makes a 90 degree turn and continues another 4 feet where it connects to the vertical gas pipe by the furnace.
That's over 6 feet of gas pipe running about a foot off the floor with NO support except for at either end.
Always wondered two things:
1)What would happen if someone stepped or fell on that gas pipe (at the 90 degree turn it's nearly a foot and a half from the wall).
2)Who thought that was an OK way to run to the pipe. (I already know WHY they thought it was an OK way to run the pipe--that's the way they roll in Manassas, Virginia. Git 'r' done!)
