I am installing a new bathroom in my home. I've completed the interior sub grade sewer and have exited the home through the stem wall sloping 1/4"/ft. I need to turn a corner to head toward the existing sewer line in my yard. Can I simply do a 90 degree or would it be better to do 2 45 degree turns. Thanks

Use 2- 45 degree turns here... code requirement... :)

Where is your main line cleanout? It should be located within 18" of the inside or outside of the foundation wall... let me know.

Thanks, there are no cleanouts currently on the property. Is it helpful to add a cleanout going with the flow and another headiing into the home? Also, my 1/4" per foot slope will put this new drain about 12" above my cast iron sewer line heading to the street. Can I do a 90 down or should I do 2 45s? Thanks.

There should be a cleanout inside the building at the base of the waste stack... if present then that is the only cleanout needed for inside the building. That would leave you with a cleanout going with the flow of the drain. Code requires that cleanout to be within 18" of the inside or outside of the foundation wall. A cleanout going into the home, or against the flow, is not common plumbing practice.

In terms of the 12" above the cast iron main, use the 2- 45s again as these fittings make it easier to negotiate a snake down the drain should the need arise in the future. Be sure to connect into the main off a WYE fitting.
