Today I was in my basement and it smelled like sewage really bad. When I flushed the basement toilet it had a lot of air push back up into it and into the shower drain too. Like it gurgled a lot. I went to the sewage ejector pit and could hear the pump making a motor sound but it wasn't pumping the sewage. I unplugged it and plugged it back in. It immediately started pumping the sewage and it is now acting fine.
What could have caused this?
Should I be worried?
