I need to install a sump pump for my wet basement. A regular sump pump installation would surely do the job--but I am afraid that I will be paying for electricity to lower the neighborhood's water table. About 100 feet from the house the grade is below the basement floor. This allowed me to siphon the basement dry using a garden hose. Is there a way I can set up a sump pump so it works to start a siphon then shuts off and lets gravity do the rest?
