Where does the current sump pump discharge? Does it actually have ground water to discharge as well? Do you have city sewer or a septic system?
In many places it is not allowed to discharge a sump pump (ground water) into the city sewer. It also isn't a great idea to discharge it into your septic system - depending on the circumstances, the flow could be significant and overload the system. What you have probably does not meet current code. My unprofessional opinion.
