Title: Automatic sub-floor pumping system

Abstract: Hydrostatic pressure, which builds up from gravity and forces water into a basement through the floor or lower walls, is relieved by sensing the water under the floor and pumping out the water to a drain or area away from the house. Thus, the water is prevented from ever entering the basement, and the basement remains dry. The invention senses and removes water simply by means of tubing and sensing wires inserted through one or more small holes which are easily drilled in an existing basement floor, for example by using an impulse drill with a carbide tipped bit. Both the sensing of the water level and the pumping out of the sub-floor water are accomplished through these small holes drilled through the basement floor in trouble areas, eliminating the need for gutters, channels or sumps.
