Back flush toilet in basement
Posted by ABL on January 03, 2004 at 11:12:12:
I would like to install a back flush toilet in the basement and tie it into an existing 3inch PVC stack. The stack has a cleanout just above the floor that I would like to use for entry of the toilet drain for convenience. Is this acceptable? I could use a wye out of the stack to keep the cleanout.
Also, in venting the toilet drain, there is a 1.5 inch vent from a floor drain that is about 12 feet away that runs up to the roof. Can I tie the vent from the new toilet drain into this vent (would be about a 12 foot horizontal run)?
