Seriously, the SS here costs about $1 a pound. I bought a 6 ft length of 1/2 SS for a few dollars. Those tanks would have been a couple of hundred each. A steal if a brewery can use them.
The pipes are around 2" diameter, but vary a bit.
Day after day, it reappears. Night after night my heartbeat shows the fear. Ghosts appear and fade away. Come back another day.
