Automatic sub-floor pumping system
First Claim
1. A method of removing water from a basement having a basement floor laid over sub-floor material, using a pump having a suction input connected to a suction hose and a drain output connected to an outflow, the pump, when activated, pumping fluid from the suction hose and exhausting the fluid to the outflow, the method comprising the steps of:
- a) connecting a plurality of pickup tubes, each having an open lower end, to the suction hose;
b) providing a plurality of holes extending from the basement through the basement floor, each hole being of sufficient size to permit a pickup tube to pass therethrough;
c) preparing a cavity under each of the holes;
d) inserting the lower end of a pickup tube through each of the holes into the cavity under the hole;
e) providing a water level sensor in at least one cavity, above the lower end of the pickup tube;
f) activating the pump when the water level sensor detects the presence of water;
g) providing a water sensor located on at least one of the pickup tubes above the lower end thereof, h) providing a valve in the suction hose leading to the pickup tube provided in step g, and i) providing a sensor controller connected to the sensor provided in step g and the valve provided in step h, such that the valve is open when the sensor controller detects the presence of water at the water sensor.

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.

3. An automatic sub-floor pumping system for removing water from a basement having a basement floor laid over sub-floor material comprising:
-
a) a pump having a power input a suction input and a drain output such that when power is applied to the power input the pump is activated and fluid is pumped from the suction input and exhausted to the drain output;
b) a pump controller having a power output coupled to the power input of the pump and a sensor input, such that when current flow is detected on the sensor input, power is applied to the power output and the pump is activated;
