ooh ooh that smell!

Hello helpful people.
I have another issue:
Not sure if it is related to the clogged sink or not, but
When it is windy outside, I sometimes get a disgusting and lethal backup of septic gasses that somehow backup into my main level bathroom.
Other times, I smell it when I run the washer, or shower on the second floor.
It always seems to happen when I am planning on having a gathering.
Not the best time for it to happen.
Thanks for any advice ( other than to move)

No one here is going to know how far above your roof the vents are or there locations. If there not above the roof enough or there blocked by a dormer or wall then the passing air across the top of them may not be enought to draw up the gas until it builds up.

they go about 2 ft above the roof, and are not obstructed by anything

Pick up some draft diverters for the vent stacks AKA vent filters they may help. common problem. Look on line, you'll need the pipe size for the vents.

Experience is Knowing what to do next, Skill is knowing how to do it

I'm kind of curious if it's possible you don't have a P trap at a fixture and it's allowing gases to escape inside the home. I suppose that is a possibility.
