Have a kitchen and bathroom stack each near the rear of the building. Trying to prevent sewer backup through floor drains so want to switch to "overhead" sewers. Connection to the city sewer is in the front of the building. Getting some conflicting information

Some plumbers have indicated that going out through the foundation as near to the stack as possible would be best, then run the drains to the city sewer outside of the building down the length of the building. Others have recommended to go inside the wall, and then punch through the foundation at the front of the building.

To me it seems "easier" to go inside, but its probably going to take up living space by needing to build soffits/etc. within the basement space which we are hoping to convert in the near future. Downside to running the pipes outside is that they will be more subject to the elements as it would likely exit the building at point that is above the frost line (we live in the a major northern midwest city).

What would you do if you were me?

Thanks!

I would go outside, and save the inside space. Houses will have two penetrations with the two paths coming together in the front yard.

I would go inside as the windy city is known for freezing temperatures.

Having any back pitch or a stoppage in the below freezing temperatures can cause the waste line to freeze and bust.

Pipe goes thru the basement wall underground. I don't know that it has to be totally above the frost line.

The line running around the house will usually be pitched shallower than 1/4 inch per foot.

good point. I would imagine they would go out somewhere below the frost line but that may require us to be closer to the front of the house to maintain sufficient pitch. Either way seems like it will work and not having to dig will be cheaper.

Hey, wait a minute.
