Rule 500GPH Electronic Sensing Bilge Pump - 24V

Rule 500GPH Electronic Sensing Bilge Pump - 24V. The pump will turn on every 2-1/2 minutes for about one second to sense for water. If water is present the pump will sense resistance and continue to run until all water is removed. After that it will resume checking for water every 2-1/2 minutes. Water is kept in check between 1/8" and 3/8". Improved design and performance means that our new 500 GPH pump will produce this flow at just 12 volts rather than 13.6 volts as previously required more ty
