Ours doesn't do that so I suspect your pump assembly is due for a rebuild or replacement. If it it a Jabsco manual toilet, you can replace the entire pump assembly ( Jabsco Part No. 29040-3000 Pump Assembly ) for little more that the cost of the parts ( 29045-3000 Major Service Kit ), and everything inside the pump, including all check valves, is then new.
