At this newly purchased home, the owners were seeing that during rainstorms, water would enter the basement under the wall where the floor meets. We replaced the old sump pump with our TripleSafe pump system, which has a twin liner, and the UltraSump battery back-up system with a control box alarm. These three pump systems calibrate automatically to meet the requirements of how much water is pumping out, and the battery backup will protect your home from flooding during power outages.
