I am adding a second story to my ranch house, and placing the new bathroom mostly over the existing downstairs bathroom. I have read something about a "wet vent" and did not understand exactly what it was. I am wondering if I can use the main vertical vent from the downstairs toilet for the drain for the new upstairs toilet.
I also need to extend a gas pipe for a seperate heating system up stairs, and want to know if I can use regular black pipe and can it be joined with teflon tape. I have done lots of piping for factory compressed air systems is there anything special I should know for gas piping.

Teflon tape is not recommended for blackpipe. Blackpipe is made for gas, but use thread seal compound and remember to check all joints for leaks.
