Glentronics Inc.’s new line of combination primary and battery backup sump pump systems is part of its growing PHCC Pro Series brand. The “Pair of Pumps” couples an energy efficient primary pump and battery backup pump into one compact system. The primary pump operates off AC power. If the power is interrupted, or more water is coming into the sump than the AC pump can handle, the backup sump pump will begin pumping automatically. The units come pre-assembled for easy installation and include four float switches for ultimate protection.
