    The existing should have a vent, the second lav will need a vent added.

    Old thread I know. I will learn how to search, start a thread and all that but happened to be reading this. I am plumbing two bathrooms with a common wall for the plumbing. Two lavs in one room and one in the other. Just to confirm, this picture is okay for venting purposes, correct? And for plumbing the sink in the other room, could/would I just tie my vent in above the vertical vent pipe shown in the picture and run a separate drain to tie in under the floor? Thanks.

    I do not see the "grounding wire",' but if there is one, it does NOT connect to the hot water piping, unless you want to replace your water heater sooner than you should have to. why would someone need a "third drain"?
