Hi all,
I'm putting a bathroom in my basement and am currently working on the plans to submit to the city. With my layout, I am planning to use an AAV behind (in the wet wall of) the shower, in a 12" wide space that will likely double as a narrow storage cabinet. This will vent the shower and, ideally, serve as a wet vent for the toilet, as per the following diagram:
My question regards the turn from the shower drain past the AAV vent takeoff. Per the Ohio Revised Code:
708.1.4 Changes of direction. Where a horizontal drainage pipe, a building drain or a building sewer has a change of horizontal direction greater than 45 degrees ( 0.79 rad), a cleanout shall be installed at the change of direction. Where more than one change of horizontal direction greater than 45 degrees ( 0.79 rad) occurs within 40 feet (12 192 mm) of developed length of piping, the cleanout installed for the first change of direction shall serve as the cleanout for all changes in direction within that 40 feet (12 192 mm) of developed length of piping.
Does my shower drain meet the criteria of a cleanout in this situation? It seems to me that without a cleanout meeting the above requirements, I will need to reimagine my DWV layout.
Thanks for any input!
