The Vevor sump pump alarm is designed to monitor water levels in sewage pits and alert you before overflow causes damage. It features dual electronic HI and LO sensors for precise pump control and automatic operation based on water level. An 85 dB alarm sounds if drainage exceeds 20 seconds, helping identify pump failure or clogging quickly. The extended 16.4' sensor cable allows flexible installation in a variety of indoor or outdoor setups. Built for compatibility with common 1 HP sewage and utility pumps, it helps improve efficiency and reduce unnecessary pump cycling.
