Smell from basement bathroom when it rains

Hi everyone,
We've recently finished our basement, which includes a full bath that utilizes an indwelling macerating pump for effluent disposal. (We had the contractor rough in all the plumbing before the concrete was poured, etc).

Everything works well, until it rains heavily. At that point, we frequently get noticeable bathroom smells in the house which clearly come from the (supposedly sealed) container that houses the pump. The vent stack and waste lines coming from the pump have flanges that go through the container lid, and my husband sealed them with silicon after the plumber got everything hooked up.

Does anyone have a suggestion on how to fix this, or what the problem might be?

How is the vent stack run through the house. Does it go up through the house and out the roof or does it go through a wall?

It goes up through the roof. (The whole DWV system for the basement bath was roughed in during the construction of the house)

Have you found the answer/fix for this. We have the same problem. Our house was constucted in 74 and the basement bathroom vents through the roof.

Did you have sewer backflow valves installed?
perhaps what is happening is storm water is surging through your waste pipes in a reverse direction, then suging forward and pulling or vacumning out all the traps, including the toilet...!
