Seems like the 3 acceptable choices are:
1) Black iron pipe
2) Copper pipe
3) Chem-Aire Industial plastic piping from Nibco
The cost of a 10 foot X 3/4" length of each are:
1) Black iron - ~ $9.00
2) Copper - ~ $23.00
3) Chem-Aire - ~$18.00
I had a cheap made in China iron pipe threader once; I don't think the thing
could thread a Slim Jim. There is a place in Seattle that sells Chem-Aire.
The fitting prices are not outrageous. I think for cost and ease I am going
to use the Chem-Aire. It will cost a bit more then black iron, less then
copper and it will be much easier to install. They also have a Chem-Aire to
copper fitting so I can use copper if the needed. This time I am going for
ease of installation.
I should be doing this at the end of January so I will let you know how it
turns out.
