basement bathroom ejector pump smell

Author: tom_mac (NJ)

I have a basement bathroom with shower, toilet and sink. When I run shower for a few minutes, pump kicks in and sucks water from toilet. The toilet refills and methane smell kicks in. Also have gurgling sound sometimes after flushing.

I can use sink and toilet all day without any methane smell. I've already made sure there is no blockage in exterior pvc air vent.

Any ideas are greatly appreciated!

Thanks M
Author: tom_mac (NJ) Thanks M. By "inlet", do you mean the intake pipe coming from the bathroom fixtures? Edited 1 times.

Author: tom_mac (NJ) M - I ran shower and open cord seal lid on pump tank. The water is at least 5 inches below inlet when the pump kicks in. The smell wasn't there this time, but the pump still sucks toilet water out -- is that normal?
