I am in the middle of my basement bathroom project and someone has suggested a shut off valve in the 3" drain before it hits the stack. My house sits quite high from the road but i still thought the idea was good enough to explore. I was looking for a 4" shut off valve to install in the line if such an animal exists. Does it? is this a practice that is suggested? If it does exist does it exist in PVC?
