    First post and looking for advice on drain and vent layout for new basement bath. I'm tying into existing main in the slab and I have two specific questions. 1) Can the toilet connect to the main upstream of other fixtures if provided all are properly vented? 2) If the toilet is within 6' of the stack, but the stack is upstream of the wye connection for the toilet does it need a separate vent?

    A toilet can be installed ANYWHERE as long as it is properly vented, and the other fixtures are also. Whether the toilet would need a vent has NOTHING to do with how close it is to the stack, but rather HOW it is connected and how the other fixtures relate to the connection.
