Primary & Battery Backup Sump Pump Systems
A sump pump is designed to pump out stormwater and groundwater, collecting in the sump pit where the pump is placed, taking the water to the city storm sewer, or out in the yard far from the house. In addition, it serves as an essential part in keeping the basement dry. When the sump pump is overloaded or damaged due to the weather, which can cause power outages, the battery-powered backup will take up the slack.
Primary and backup sump pumps require a 1½-inch PVC pipe for the discharge line, though there are exceptions that require the pipe to be 2 inches. The external component requests a set up distance of 2 inches, creating a freeze gap between the 2-inch and 4-inch underground discharge lines. The freeze gap is in the event the pipe does not drain for any reason, such as clogging.
