I have a full bathroom in my basement, as such I have a pump that pumps the waste upwards and onto the main sewer line. What is the best way to keep the pump clean and deodorized to make sure there is no sewer odor in the basement. Would appreciate some help. Thanks in advance for your help

The ejector pump and pit should be completely sealed so you don't have to worry about sanitizing it. You'd have to sanitize after every flush because you know what just went into the ejector. Does the pit have its own vent? If so you should be in fine shape.
