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,

jb9

Your home drainage lining is connected with the main sewer drainage. Sewer drain connects to the main street drainage. The problem is when these drains gets collapsed you need to open entire line of drainage. I would like to ask if we have an other solution rather digging and repairing this pipe.
 
collapsed means the pipe is broken, and has closed off due to the weight of the earth
i really do not see any way to restore a broken crushed pipe.

keep in mind. the pipe also is installed with a smooth,continuous slope
once it is crushed. that smooth service is gone. and now you will have a ''belly'' instead of continuous slope
that is a prime area for stuff to accumulate and plug up

if the pipe is not collapsed. just full of grease or root bound. it can be rodded out and sleeved

yes. most definitely, as long as you have the correct slope from the sewer invert at the main house to the invert at the added building
4'' 1s 1/8'' per foot slope. [[[[[[1 1/4'' per 10']]]]]]]


this what i would do, add clean outs, you will thank your self latter

Since this original question was posted almost 3 years ago, I suspect it may have already been installed.

"The problem is when these drains gets collapsed..." :confused::eek::rolleyes:o_O
