Battery-backup sump pump systems offer insurance in case your primary pump fails due to a power outage. They are affordable and fairly easy to install. This system (a Basement Watchdog by Glentronics Inc.) fits in a narrow or wide sump pit.
To give you an overview of the process, here are seven step-by-step photos. The manufacturer provides complete instructions and diagrams with the product. Basement Watch Dog is another great source of information and sump pump installation videos.
1. Start by laying out all of the pieces needed for the preplumbed combination sump pump system.
2. Disconnect your system’s discharge pipe, and remove the check valve and the old pump from the sump pit.
3. Lower the preplumped combination pump into the pit. This system includes two built-in check valves.
4. Reconnect the discharge piping with a rubber slip coupling.
5. Hook up the battery. Note that a fluid sensor has been inserted in the hole of the yellow battery cap.
6. Plug the control unit into a GFCI-protected receptacle. Then plug the pump into the controller.
7. The completed job: A sump pit cover helps to control moisture and noise and prevents debris from falling into the pit.
