How many times are you worried about basement flooding during a storm or prolonged rainy days? Or have you already had to deal with the mess of a flooded basement? A power outage or pump malfunction can happen at the worst time. Even battery-powered backup pump can fail or simply run out of battery. Keep your peace of mind with the Fortress Sump Guard. It's a modular flood wall system that can be easiely assembled around the existing pump fixture, and can be easily dissembled when necessary. The best protection is a passive device that relies on basic physics: water doesn't flow up. The Fortress Sump Guard measures 3 feet tall, higher than the typical basement window sill. Water is always contained within the guard wall unless ground water level rises above the basement window (practically nothing will work if that happens, as that means the window well is already flooded).
