Is there anything wrong with installing a 3" ABS back water valve in a drain that is not below a concrete slab?
This is the style I am speaking of, and they usually come with a sleeve and cap meant to be cut flush with the top of the slab...
This is the 3" into 4" waste line exiting my house. The 3" line is 20" from the slab. (bottom right corner)
