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.

A method and system is provided for insulating piping installed in an exterior wall in a manner that protects the piping from freezing. Generally, the system includes an insulation block that has an interior side, an exterior side and a slot formed therein for receiving a pipe to be insulated adjacent the interior side, wherein the block is dimensioned particularly for installation into a building wall cavity. When installed, the block insures that the piping is positioned immediately adjacent the back surface of the interior sheathing material. The insulation block reliably provides a thickness of insulation material behind the piping such that the insulation material is positioned between the piping and the exterior wall surface while also maintaining the piping in contact with the rear surface of the interior wall sheathing to facilitate heat transfer from the interior of the building and into the piping.

An above-ground, double-walled, tank for holding combustible material and supporting a generator has an outer tank and an inner tank with structural baffles, all made from type 316 stainless steel. An interstitial space formed by the outer tank and inner tank is filled with a fire resistant solution consisting of a fire block gel and water. An internal support system, including structural baffles in the inner tank, provide a structure to support a generator and other equipment on the top of the tank without the use of tank wall stiffeners or external beams. A level detector in the interstitial space detects changes in the level of the fire resistant solution. A water detector in the inner tank detects the presence of water. The fire resistant solution may be removed from the interstitial space for tank inspection and repair.

A safety heat exchanger for combining a heat pump with a device of a drinking water supply facility for obtaining heat from drinking water. The heat exchanger includes a primary circulation loop (4) with drinking water, a secondary circulation loop (6) with antifreeze as a material that does not pose a health risk, and a tertiary circulation loop (7) with a coolant. The primary circulation loop (4) includes an inlet (3) connected to a drinking water supply facility and an outlet (5) with electrically controllable magnetic valves (16). The secondary circulation loop (6) and tertiary circulation loop (7) each have any dedicated difference pressure monitor (9, 18), which difference pressure monitors (9, 18) are controllably connected with the magnetic valves (16) such that when the difference pressure monitors (9, 18) detects a pressure difference in the secondary circulation loop (6) and/or in the tertiary circulation loop (7), the inlet (3) and the outlet (5) of the drinking water to the drinking water facility are closed, wherein the difference pressure monitor (9) of the secondary circulation loop (6) comprises an expansion vessel (11), a safety valve (12) and a manometer (13).
