An underground plumbing system for inhibiting debris from entering an underground valve box includes a valve box that may be buried in ground. Thus, an underground plumbing fitting may be housed within the valve box. A lid is removably positioned on the valve box and the lid is positioned to close the top side. A shield is removably positioned within the valve box. The shield inhibits debris from entering the valve box when the valve box is buried. Thus, the shield inhibits the underground plumbing fitting from being covered by the debris.

A system of modular boxes as shown and described can be interconnected directly to one another via connectors that are integrally molded with the sidewalls of the boxes. The connectors of the boxes may include fastener receiving apertures for receiving a stud-mounting fastener therethrough. The connectors are thin and flexible, such that insertion and forcible tightening of a fastener through the aperture will cause a compressive force to be exerted between the interconnected boxes to maintain their spatial relationship and to maintain their interconnection. A further feature of the modular boxes of the system are anti-rotation members and receivers that are integrally molded to the side walls of the boxes. The anti-rotation members and receivers interact with one another at the point of connection between the boxes to prevent the boxes from flexing, rotating, or otherwise moving with respect to one another post-installation.

A meter pit tile extension assembly is provided. Illustratively, an inner ring is attachable to a pit tile. The inner ring includes a first set of a plurality of outwardly extending ribs. A first space located adjacent the first set of the plurality of outwardly extending ribs. An outer ring is provided that is telescopingly positioned over, and vertically movable with respect to, the inner ring. The outer ring includes a first set of a plurality of inwardly extending ribs. The first set of the plurality of inwardly extending ribs of the outer ring are selectively positionable in a first position in the first space between the first set of the plurality of outwardly extending ribs. The outer ring is also rotatable with respect to the inner ring. Rotation of the outer ring with respect to the inner ring causes the first set of the plurality of inwardly extending ribs to be selectively positionable in a second position such that at least one inwardly extending rib of the first set of the plurality of inwardly extending ribs is selectively positionable adjacent at least one outwardly extending rib of the first set of the plurality of outwardly extending ribs.

The invention is configured for water-supply and comprises the vertically oriented hydraulic accumulator; the inlet and outlet connections; the connected to the hydraulic accumulator filter with the removable cartridge, located in the casing; the hydraulic accumulator is made in the suspended manner and equipped with the commutator with a flange for the attachment to the hydraulic accumulator, located in its lower part; the commutator is made with the channels, connected with the inlet and outlet connections, and with the holes for the controlling and regulating equipment attachment; and the filter casing is installed on the thread at the commutator. The technical effect—the size is reduced and the structure of the device is simplified due to minimizing the number of transition and connecting parts, while simultaneous improving the conditions for the monitor and control of water supply modes from one work place—from the commutator, which is the set of equipment for the device control automation in general.

A water service supply assembly includes a water supply line with a stop valve. A lid is supported relative to the stop valve. A first switch is adapted to detect movement of the lid and a second switch is adapted to detect if a body is moved relative to the stop valve.

A system and method of providing a high temperature hot water system assembly including a direct buried valve box that connects to one or more underground service pipes is disclosed. The buried valve box contains a valve assembly configured to control the flow of water through the one or more service pipes. An air gap within the valve box allows for movement and expansion of the components as the temperatures rise, preventing cracking or other failures. A bypass valve is also provided within the buried valve box, allowing for a small amount of hot water to flow through the service pipes to gradually increase the temperature. The direct buried valve boxes, controllable through valve risers that terminate in surface assembly boxes, eliminate the need for large, concrete underground vaults that make maintenance and operation of valve assemblies more difficult.

A flushing station for a ring-pipe or series-pipe system, comprises a cold water port for connecting a cold-water pipe, a hot water port for connecting a hot water pipe, and a waste water port, wherein the cold-water port and the hot water port are fluidicly coupled to the waste water port. The cold-water port, the hot water port and the waste water port are assigned to a bottom side of the flushing station.

A dialysis service box for centralized control and plumbing arrangement of a dialysis machine is disclosed. The dialysis service box includes a plumbing arrangement with a warm water inlet and a cold water inlet in fluid flow communication with a temperature mixing component. The thermostatic mixing component mixes the cold water and the warm water to produce mixed water maintained at a predetermined temperature between the temperature of the cold water and the temperature of the warm water. The dialysis service box can be universally installed to operate, control and adjust any dialysis machine that requires supply connection, waste connection, backflow preventer, thermostatic mixing component, a trap primer, or any combination of the foregoing.

A sprinkler valve box has a housing, the housing having a base and sidewalls with a sealable lid thereon. The sidewalls may have one or more connecting ports therethrough. The housing has one or more pre-configured valves therein. The valves may be coupled to the one or more connecting ports in the sidewalls. The sidewalls are ideally corrugated for added strength and the lid seats over the sidewalls of the valve box, which may be lockable. The sprinkler valve box may also have a battery and a control unit, wherein the control unit is powered by the battery and controls the valves of the manifold. The control unit may be controlled wirelessly by a user.

A universal rough-in valve (20) includes a valve chamber (34) configured to receive a valve manifold (72). The universal rough-in valve includes a first valve inlet (22) configured to provide a pathway for fluid from a first supply line to the valve chamber and a second valve inlet (24) configured to provide a pathway for fluid from a second supply line to the valve chamber. The universal rough-in valve includes a first valve outlet (29) configured to provide a pathway for fluid from the valve chamber to a first outlet line, and a valve manifold (72) coupled to the valve chamber.
