Hello,
I am going to be building a single family house along with a detached garage (or accessory unit). The detached garage/accessory unit will be built in the future at a known location on the lot. The lot is only .22 acres so I don't anticipate that location changing. I know how I want to run the main 4" drain line out to the sewer hookup. What I want to know is how I can intelligently plan for the second structure to be hooked into the main 4" drain line. I have attached a simple schematic to show the location of the main house, the sewer line and the location of the future accessory unit. Can I put a wye on the end of the branch and cap it off with the goal of eventually adding the branch to the accessory unit? Sorry for the quality of the drawing... I just want to hear how a pro would approach making the future connection of a 2nd branch simple and intuitive (keeping all the lines as straight and clog-free as possible).
Thanks,
