Canton
Plumber
I'm wet venting a basement bathroom off the lav, my intention was to bring it up to the attic and tie into the stack going out or vent it separately. Unfortunately, I'm having a hard time getting upstairs, I tried following the chase where the 4" waste comes down but the chase was reduced and I can't get it up there. I'm in Massachusetts and automatic vents are prohibited. My question is how are the automatic vents, do they work, and what problems could you encounter if I decided to use them.
