Hello,
I have an old farmhouse, the build date is unknown, but is thought to be at least 120 years old. There's been a lot of shoddy work done to her over the years, and I'm trying to make things right the best I can without completely demolishing the place.
Anyway, I have been noticing some sewer (septic) gas coming up from the master bathroom, even in the warmer weather, but it's been especially bad since the winter hit. I suspected a drain vent issue, but it took me a while to figure out where that even tied into the rest of the drain. What I've found is a pipe in the basement, coming out one side of a wye, running up an external wall, and going up through the roof. There doesn't seem to be any place where any other pipes/drains/vents attach to this pipe, and this is the only vent coming through the roof. I will post a link to the image on my Google drive for anyone to look at. For reference, this pipe is only 1-1/2", which I understand is pretty small for a waste vent.
Here's the picture (the pipe on the right that goes into the foam insulation):

The questions I have are:
1. Is this design just too flawed to work properly even if the pipe is clear? Referring to it's placement in relation to how the drains come in, not to mention its size.
2. Would it be feasible to cut into this, adding a cleanout tee, and trying to snake it from the basement going upward? My roof is piled up with snow at the moment.
I welcome any thoughts or suggestions from anyone who is familiar enough with DWV function and design. I'd rather not tear up my walls if I don't have to, but I also am not keen on poisoning myself or my family by not making an effecting fix.
Thank you all so much!

you really have quite a mess there..
there is a big pipe draining into a little pipe.
the rubber coupling down low is sagging so it will catch debris.
lots more wrong as well
probably best to rip it out (leaving the cast iron fitting at the wall) and start again.
sorry..
