Hi Folks!
First time poster but long time visitor. I'm wondering if you could help me decide if the plumbing - specifically the venting - in this bathroom install is something I can do.
Like many, I spent lockdown finishing out the basement of my 15 year old house. I have one room left and it has the plumbing in it:
From left to right we can see: radon vent, black thing in the floor (hopefully a backflow preventor), a floor drain for the condensate from the AC unit (behind the unit, not shown), a 2" pipe with an AAV presumably for the floor drain, a WC/CO stub up, another 2" pipe capped, and the main drain from the two floors above.
This is where the main goes into the slab. Interestingly (?) the street is 180 degrees from the turn of the pipe.
Lav and Vent - this is where I want to drain a lav in one room and a slop sink in the other room.
The WC stub. Centerline is a little over 17" from the concrete wall.
What I hope is a backflow preventor - I've never seen one!
And the AAV.
Above all this, running parallel to the wall is the drain line that has the master bath, hall bath, and laundry. The left is the branch to the hall bath, the right is the drain from 2nd floor bath.
At the end of this branch is the master bath (shower, WC, two lavs) and the drain from the laundry.
SO! How to vent this? There is only one vent pipe on the exterior of the house and it is above the main drain. Is it possible to tie into the laundry drain somehow? Or would that lead to sewer smell coming in the laundry room?
Many thanks for all your assistance!!
