Don't get caught off guard by a flooded basement or a failing septic pump! This Zuomeng high-water alarm is your early warning system. It uses a float switch that you place in your sump pit, septic tank, or any water collection area. When the water rises too high, the control box lets out a seriously loud 110-decibel alarm and a bright flashing light to get your attention. You can also wire it to automatically turn on a submersible pump (up to 20A) to start draining. The alarm circuit and pump circuit are separate, so even if the pump fails, the alarm still works. The casing is rated IP67, meaning it's totally dust-tight and can handle being submerged in water temporarily – great for damp, harsh environments. It comes pre-wired for easier installation. A must-have for anyone with a basement, a septic system, or a lift station to prevent costly water damage.
