Hi,
I'm putting in a new bathroom on the third floor. I don't have good access to the existing stack, so I'm going to run a new, additional, 3" stack. The drain will service a toilet, bath tub and sink. I want the drain pipe to "hug the walls" to keep the pipe out of the way and box it in later.
Is there any limitation on how convoluted this 3" drain can be? Assuming I maintain the proper pitch along the way and use long radius elbows, I'm going to go down through the floor, horizontal for 2 feet, down 8 feet, horizontal for 16 feet, down 2 feet, horizontal for 25 feet, down 8 feet then 15 feet to the septic tank.
Any thoughts?
Thanks,
Glenn
