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?
