Is that pipe wyed off the toilet really a vent? Where's the stack?
Hi - So 2 plumbers had come to give estimates and they both said this is the vent. its hard to confirm but by process of elimination I have. If you look in the picture i originally attached the stack is located 15 feet back from the back wall there. I can send another picture if needed.Is that wyed pipe to the toilet really a vent? Where's the stack?
