I am adding a first floor bathroom. The first picture below (from the garage/basement) shows the waste line from the new toilet (on the left) and the existing waste line (on the right). The inspector said the sanitary tee that we used where the new toilet waste line meets the existing waste line was improper, and should be a wye. As you can see, a wye with a single 1/8 bend wouldn't work here because of the joist and how close it is to the other wye. So in the second picture, you can see my solution--which is to add a 90 and a 45. Are there any issues with this solution?
