Hello All,
I am roughing in a second floor addition to our home and I'm comfortable with all the code requirements for DWV except the cleanout requirement for a horizontal run for a 3" pipe from the toilet to the stack. My concerns are around the number and degree of bends. I have created 3 plans which only show the toilet to stack run that I would appreciate comments on.
Plan #1 has 2 90 degree turns + a 22.5 degree turn at the stack so I therefore assume it is not allowed.
Plan #2 uses two 45 degree turns + a 22.5 degree turn for a total of 112.5 degrees which I assume is allowed (less than 135 and no 90 degree turns).
Plan #3 is the one I can't decided if it is valid or not. I use 45 degree bends separated by 6 to 12 inches of pipe to make up my 90 degree turns. The total degree of change for this plan is the same as plan #1 but no turn is greater than 45 degrees. This would be valid if I am correctly interpreting my "Code Check Plumbing" book which says IRC "if more than 1 change in direction in a run of pipe, only 1 cleanout every 40ft. required." I don't have a warm and fuzzy feeling about this and wanted to ask the pros.
Thanks in advance,
Jeff
