I have taken everyones advice and decided to break concrete in my basement for new bath. My 4" PVC waste line is about 9" from the wall and there is an existing cleanout "T" about 3' above the floor. My run will be about 14' from this pipe to the toilet with a sink and tub following along the wall. My greatest concern is how deep the existing fitting that changes from horizontal to verticle is under the concrete. Short of breaking the concrete, is there a way to determine how deep this fitting is?
