A primary sump pump is typically 1/3-1/2 hp and A/C powered. They are cheap quiet and efficient, clearing your pit in a matter of seconds. Mine sees heavy use, pumping at least once per hour, all year round.
This is a 1/6hp system that runs off of a battery... so it is intended as an emergency backup system, ie. during a rainstorm when you have a power outage. However, if there are no laws regarding the size of your sump pump, this might work fine as a primary for light use... but then what will you use as a backup system?
