Hi all,
New to this forum and hoping to get some support in a disagreement I'm having with my plumber. We are remodeling an upstairs bathroom which entails moving the laundry upstairs and reconfiguring the existing shower. Plumber has completed his first day of work and has the drains laid out such that the shower would wet vent through the washing machine drain. I'm fairly certain this isn't allowed, and think I understand why (high volume of washing machine drain flow could siphon away the shower trap seal and create odor issues).
He has sent me the attached, but I don't believe this applies as the washing machine is an appliance, not a bathroom fixture. What I'm hoping for is 1) confirmation that my understanding is correct, and 2) a specific section or sections in the code that I can't point the plumber to so that he's compelled to fix this. Project is in Marin County, CA.
Any advice is greatly appreciated.
