I'm adding a toilet and Shower to my basement and I'm unsure on the venting. My vanity is on the other side of the main drain and is straight forward. Please see the diagram I've attached. I have the Toilet venting up through the wall between the shower and toilet, and the shower emptying into the 3" toilet plumbing downstream of the vent. Do I need another vent after the shower joins in?
