Black pipe for water lines

I saw this and thought what is this on the gas line for so I followed the black pipe and it went to the water inlet :shock: it was on both side of the water heater as well.
Bet that water tastes good. :roll:

So what Ken, you get your daily supply of iron and can see how your supplies are holding up by following the rust spots.

I like the needle valve stuck into the pipe, why waste money on copper when black pipe is so cheap?

Not good if you have homochromatosis…

How the hell did you know about that?

In that case one would use lead pipe, silly. :razz:
