The SmartSump sump pump collects any water in the space and ensures it is discharged outside of the home. This system includes an airtight lid to prevent the water in the sump from evaporating into the crawl space. A pump alarm is also included that tells you when the sump pump is not working so you can deal with the problem immediately. If a plumbing leak were to occur, this system also comes with a floor drain that lets water enter the sump pump immediately, without letting damp air out.
