I am doing a large 2nd floor bathroom remodel and the toilet will be in a new location. The main stack in my house goes up vertically from the basement and then goes horizontally in a soffit under the 2nd floor. It then goes vertical and into the attic and out the roof.
The location of the new toilet is directly (literally) above the horizontal 3" drain. I was hoping to be able to have the 3" toilet drain go down and connect into the horizontal drain below. I have been made aware that there are potentially 2 issues with my plan for the new toilet:
1) A direct connection from the vertical toilet flange should not be made to the horizontal drain with a sanitary tee. If a direct connection is made, it should be with a tee and 45 angle.
2) The vent that goes to the attic upstream from the toilet cannot be used as a vent because the horizontal drain also acts as a drain for the 2nd bathroom that is further upstream. This means that a new vent is needed for the toilet.
So my questions are:
How can I successfully put the toilet in the new location? Do I need a separate vent for the toilet since the existing vent cannot be considered a vent for the toilet? Can a vent be added down stream of the toilet in the horizontal drain?
The center of the horizontal drain is 22" from the wall. Therefore, I don't have much room to have a new drain for the toilet connect into the horizontal drain via a wye. I attached pictures. I appreciate all suggestions! Need help! Thanks!
