Exterior Sewer Line
Posted by Loyal Adams on November 18, 1998 at 09:07:41:
I have recently added a bathroom to the second level of our home. Is it practical and or possible to run my 4" sewer line out through a side-wall then across (horizontal) and down to connect to the sewer line. I would need approximately 20' horizontal run which will be on the exterior of the house under a second story deck. If I can what is proper pitch and are freezing temperatures an issue.
