Is there a depth requirement for a soil pipe that runs outside a building? Old house with an addition on the back and an exterior 3" vertical wasteline from the second floor. Some previous owner installed and uninspected half bath and ran the soil pipe (schedule 35 PVC) across part of the yard and tied into the base of the exterior verticle waste stack that goes into the basement. I want to enlarge the bathroom and also bring the plumbing work up to code. To maintain pitch I will only be about 10" below grade when I come thru the foundation wall of the addition. Is that deep enough?
My other option is to go thru an 18" thick stone wall with a 3" line into the basement and install an ejector pump setup to get the waste up and over the basement area the would need to be crossed.
