I need to change from my existing cast iron drain pipes in the unfinished basement to plastic. They have not been up to code anyway.
I would like to not have to revent bathroom fixtures which are next to the main drain/vent stack. Here is a chart that I have about distances. I have a few questions about using the measurements.
When measuring the horizontal lengths of the pipe to use the chart:
1. Is 45 degree drain pipe coming from a vertical main stack used in the measurement in the horizontal measurement of the pipe? or only when the pipe turns horizonal.
2. The bath tub P-trap is in the basement. When measuring the horizontal length of the pipe from the main stack to the tub do you measure to the from the beginning of the P-trap or to the vertical pipe coming down from the tub?
