What type of cleanouts and where can they be located for the following situation?
I'm converting a second floor shower to a whirlpool bath. The main 3" vent rises from a cross positioned just below the second floor joists in a soffit in the first floor ceiling. Unfortunately, the vent rises up through the only space where the whirlpool can be positioned. For a combination of reasons, 45 degree elbows do not provide enough offset to allow the stack to pass outside the tub space.
As an alternative, can I turn the stack horizontial just above the cross with a 90 degree elbow, run horizonal a few feet until the stack is outside the tub space, then turn the stack vertical again with another 90 degree elbow?
It is my understanding that eventhough none of these rerouted vent pipes will carry water, they must have a cleanout. Is this correct?
If so, does the cleanout need to be at the end of the horizontial section? Or can the cleanout be angled up 45 degrees so that it is accessable from above the floor?
Or can the clenout be in the vertical section several feet above the 2nd floor? If so how far up is acceptable?
Finally, can the vent be reduced "one size" to 2" so that the radius of the elbow turns is smaller?
