Liberty Pumps SJ10A SumpJet Water-Powered Backup Pump with Local Alarm
Brand: Liberty Pumps | SKU: SJ10A
Product Overview
The Liberty Pumps SJ10A uses an uninterrupted pressurized water supply to pump clear sump water when the primary sump pump cannot operate. It adds a local audible and visual alarm to the SumpJet water-powered backup design. The pumping mechanism does not need an electric motor, but the alarm has its own electrical and battery requirements. Confirm a municipal water supply that remains available during power outages before ordering.
