I have a toilet, sink and bath tub connected to a grinder sump pump. When ever you take a shower or bath air bubbles up out of the toilet. Is there any way to stop this? I have a vent on the sump tank. Thank you for any suggestions and or solution you provide.

pad99chev, Welcome to the DIY Forums.
Each fixture (sink, toilet, shower) has to have its own vent. Most are tied into a main vent by going up the wall behind the fixtures at a higher elevation. You are basically pulling a vacuum on the toilet when using the other fixtures. This is dangerous as you are pulling the water from the toilet trap which allows sewer gases to enter through the toilet bowl. Good luck.
