Maximum number of 90 degree bends in drain?
- I couldn't find what I was looking for to give you an official reference, but the maximum bend allowed is 135-degrees. For example, a 90 and a 45 or 3 - 45's. If you need more, you're doing something very wrong and need to reconfigure your plan. Also, always use Wye's whenever possible for any orientation. Tees and Sanitary Tees should only even be used vertically.
