WATER LEAK DETECTION, PREVENTION AND WATER CONSERVATION SYSTEMS AND METHODS

A water leak detection and prevention system uses sensors, wires, and wireless transmitters, to monitor all plumbing fixtures (faucets, toilets, hose bibs, etc.) and water-using appliances (dishwashers, washing machines, icemakers, etc.). When water is being used at a plumbing fixture or a water-using appliance, the sensor shows water that is expected to be used at that location and communicates the usage and the amount of flow for that location. Excessive usage or flow, or any flow when a location has not called for water, is indicative of a leak. Water to the building is on all the time—water pressure remains in the plumbing—creating no delay in water delivery. Water pressure and water flow are monitored at all times whether water is off or on. Should a leak occur the water flow sensor will show that water is flowing and that no approved location has called for water. The main valve will immediately be turned off and water in the plumbing system will be purged safely outside the building. Plumbing system protection: Should an over-pressure situation occur—due to expanding water being heated for instance—system will evacuate a small amount of water to the outside of the building, protecting plumbing, fixtures and appliances. Temperature sensors placed on piping at strategic locations will protect plumbing from freezing. Should temperatures near the freezing point, the system will purge water from the pipes. Water conservation system: should a toilet flapper become stuck open or partially open, or a faucet left dripping or running, the system main valve will close and water will be conserved. 1. A method for protecting a home or business building from flooding caused by a leak or rupture in the building plumbing or a malfunctioning appliance comprising:when no fixture or water-using appliance (e.g., faucet, toilet, shower, dishwasher, clothes washer, refrigerator, humidifier, reverse osmosis unit, water treatment unit, thermal solar panel, etc.) demands water, a ...

Incompressible fluid for leaks

A B S T R A C T Disclosure is made of a method and apparatus for monitoring a conduit system for an incompressible fluid for leaks, wherein a testing fluid is introduced into the conduit system during a testing period when no fluid is being withdrawn from the conduit system and the conduit system is closed on the supply side by a main valve. Now, without increasing the pressure in the conduit system, a check is to be made whether fluid is escaping from the conduit system despite the closed withdrawal valve. For this purpose, without the entry of testing fluid from the supply side of the main valve (1), a predetermined test volume of the testing fluid is introduced into the conduit system (8) under a pressure of the same order as the fluid pressure on the supply side of the main valve (1) and the time required by the test volume to flow into the conduit system is measured. A suitable apparatus for this comprises a chamber (12) for introducing the test fluid into the conduit system, the chamber communicating only with the conduit system (8) and having a volume which can be changed between a predetermined first larger value and a predetermined second smaller value. Further, time measuring means (16) are provided for measuring the time during which the chamber changes from the first volume to the second volume. Single figure.
