I think the problem would be that the next person to come along would wonder why someone hooked a gas line to the faucet.....

One of the reasons it is 'discouraged' to use a black wire as neutral or a red wire as earth ground.

I would think Blue pipe would be more suited for water usage.

Blue for COLD water....RED for hot water.....GREEN for the hot/cold that comes from a mixing valve.

Ok...joking aside.....when you do work in a factory....you appreciate very quickly when pipes are painted the right color....especially when you have a bunch of them going all over the place.

Here is an example.....imagine working on something like this if the pipes and wires were not the right color.

That looks like a large DA tank for some pretty good sized Boilers. The lines I can see should be labeled with directional arrows on them.

Actually....it's a 30' x 70' autoclave. This one is used to cure the front fuselage of the Boeing 787....42' of fuselage in one cure.

I don't have a pic of the completed project....but nitrogen pipes were painted green, gas black w/yellow strips, and water blue. The stainless steel lines are for cooling...this thing can get up to 450 deg F at 150 PSI.
