A chemical solution dispensing apparatus uses a dissolving tank to hold a solid chemical cake. The dissolving tank delivers the chemical solution into a holding tank by gravitational flow and then to a receiving system. A liquid level sensor in the holding tank senses the liquid level of the solution and calls for water delivery through a conduit into the dissolving tank. When the level reaches a low point a circuit opens a inlet flow valve to deliver water into the dissolving tank. When the level reaches a high point, the circuit closes a safety shutoff valve in the conduit line. A pressure regulator and control relay enable the conduit line to be properly pressurized by an inlet source of water through a shutoff valve that is normally open. When the level in the holding tank rises above the high point, an alarm signal is released to initiate an audible alarm.

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.
