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
