A utility provisioning station for providing utility services to a consumer. The utility provisioning station includes a power supply, a water storage tank, a sewage storage tank, a communications module, an ecommerce interface, and a controller. The power supply supplies electrical power service to the consumer. The water storage tank retains and supplies water service to the consumer. The sewage storage tank provides wastewater services by receiving and retaining wastewater from the consumer. The communications module provides telecommunications services to the consumer. The ecommerce interface receives requests for selected utility services. The controller controls the power supply, the water storage tank, the sewage storage tank, and the communications module, and directs the selected utility services to be provided to the consumer.

A prefabricated part comprises a concrete body that has the form of a pipe section with two pipe ends and a pipe inner side. The pipe inner side is lined at least in some areas by a lining made of plastic material connected to the concrete body, and at least one of the pipe ends is covered at least in some areas by a molded part made of plastic material connected to the concrete body. At least the pipe end, which is covered at least in some areas, has a connecting joint in order to connect the pipe end to a pipe end of a further prefabricated part. The lining consists of a thermoplastic material and the molded part consists of a thermosetting plastic. The lining and the molded part are connected to each other in a sealed manner.

A non-invasive thermal dispersion flow meter with chronometric monitor for fluid leak detection includes a heater, an ambient temperature sensor and a flow rate sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. Based upon the ambient temperature sensor readings, the flow rate sensor and heater may be adjusted to optimize the operation of the system to detect leaks. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure. Geographic location, occupancy sensors and occupant identifiers are used to control the system to facilitate operation and minimize leak damage when occupants are away.

A wall installation connection box unit, including a box housing body having a rear-side base portion and a sleeve portion projecting forward from the base portion, which sleeve portion peripherally surrounds an installation component mounting space, which space is accessible via an open front end face of the sleeve portion, an extension sleeve which is configured for coaxial arrangement on the sleeve portion and axial pushing back relative to the sleeve portion, and a retaining structure which allows axial pushing back of the extension sleeve on the sleeve portion from a mounting position to an end use position on variable axial level and retains the extension sleeve in the end use position on the sleeve portion. Illustratively, the retaining structure includes a retaining ridge structure radially projecting from the sleeve portion, which is formed integrally with at least one adjacent axial partial region of the sleeve portion from a sealing resilient material, and a counter-retaining structure cooperating with the retaining ridge structure in a frictionally engaged and/or form-locking manner, provided on the extension sleeve and made from a material which has greater stiffness as compared to the sealing resilient material. In addition or as an alternative, the wall installation connection box unit includes a spacer element which is attachable to the box housing body in a securing position in a detachable manner, where the spacer element secures the extension sleeve in the mounting position against axial pushing back.

A bypass valve is for support between hot and cold water lines that connect to respective hot and cold fixtures. The bypass valve includes a valve body having an internal chamber, a hot water inlet port, a hot water outlet port and a discharge port; a bi-metal spring; a support member for mounting the bi-metal spring within the internal chamber of the valve body; and a shuttle mounted to the bi-metal spring and constructed and arranged to mate with the hot water inlet port in a closed position of the bi-metal spring. The bi-metal spring assumes an open position to disengage from the hot water inlet port at a predetermined water temperature to enable the hot water to discharge through the discharge port to the cold water line.

A telescoping fluid coupling (10,110) is provided for use with a fluid flow device (12) and includes a coupling body (14,114) having a fluid port (16,116) extending along a longitudinal axis (18,118). A retainer (20,120) is fixed to the body (14,114) and includes a retaining shoulder (26,126). A flange (22,122) is mounted to the fluid port (16,116) and includes a radially inwardly facing guide surface (36,136) that surrounds a mount surface (24,124) and extends longitudinally along the axis (18,118) to provide guided, sliding translation of the guide surface (36,136) relative to the mount surface (24,124) along the axis (18,118). The flange (22,122) further includes a stop shoulder (38,138) to engage the retaining shoulder (26,126) to limit the translation of the flange (22,122) along the axis (18,128).

A pit and an extension, each having flanges extending perpendicular to an axis of the pit and extension. The pit includes holes extending outwardly in the wall of the pit, preferably these holes are located at one end of the pit. Surfaces of the flanges are configured to mate together and clips secure the flanges together to inhibit movement apart of the pit and extension along the axis. In certain embodiments, the extension includes support ribs which may be both interior and exterior and the extension narrows from its flange towards an opposite end thereof.
