A check cover assembly for a backflow prevention (BFP) assembly including a dome-shaped base with an upstanding shroud, wherein the shroud forms an inner area configured to receive a test cock to support and protect the test cock. The shroud forms a gap for accessing the test cock to selectively open and close the test cock while installed in the inner area. The base forms a passageway from the inner area into the BFP assembly configured so that when the test cock is open, a pressure reading of a pressure zone in the BFP assembly can be taken via the test cock. A retention fork is in a slit formed in the shroud so that the test cock is captured in the inner area but the test cock can be removed from and inserted into the inner area without rotation when the retention fork is removed from the slit.

A leak detector assembly for use with a backflow prevention device includes a housing defining a passageway for receiving a fluid. A flap assembly couples to the housing for generating a low flow error signal indicating minimal fluid passing through the passageway and a fully actuated error signal indicating significant fluid passing through the passageway. The flap assembly includes a flap mounted in the passageway such that significant flow of the fluid moves the flap to generate the fully actuated error signal. The flap assembly also includes a sensing element on the flap to determine a presence of the fluid without movement of the flap to generate the low flow error signal based on a low flow of the fluid.

A protection device for protecting the potable water from contamination caused by backflow, comprises a housing with a potable water inlet, a first funnel, which is arranged at a distance to and aligned below the potable water inlet, and a second funnel, which is arranged at a distance to and aligned below the first conical funnel, and via which the water can be drained. An opening in the housing is formed for the discharge of the backflowing water, to which the back-flowing water can flow between the first and the second funnel.

A backflow preventer including a body having an inlet for connection to an upstream portion of a plumbing system and an outlet for connection to a downstream portion of the plumbing system, a first check valve and a second check valve located in the body for preventing the reverse flow of water between the outlet and the inlet. An inlet pressure zone is positioned between the inlet and the first check valve, an outlet pressure zone is positioned between the outlet and the second check valve, and an intermediate pressure zone is positioned between the first and the second check valves. Position sensors sense the positions of the check valves, and pressure sensors sense the pressures in the zone. A controller in communication with the position sensors and the pressure sensors calculates the opening and closing pressures of the check valves.

A check valve for a fluid distribution system can include a valve body defining a valve bore defining a cylindrical shape, the valve body comprising an annular body and a fixed cross member secured to the valve body and extending across the valve bore, a position block secured to the cross member of the valve body, extending from the cross member, and defining a pivot bore; a pivot pin positioned within the valve body and extending through the pivot bore of the position block, the pivot pin positioned entirely within the cylindrical shape of the valve bore; and a valve member positioned within the valve body and configured to rotate about the pivot pin to a closed position when a pipe system termination fitting attached to the valve body is dislocated fr om the valve body or when the fluid moves in a negative flow direction of the check valve.

Methods and systems of providing domestic water service to a commercial/residential building via a water booster pump assembly are disclosed herein. In some embodiments, the water booster pump assembly includes first and second water pipe branch circuits. In some embodiments, each water pipe branch circuit is configured with a backflow preventer and the water pipe branch circuits are fluidly coupled to one another in parallel. In some embodiments, the water pipe branch circuits are further coupled to one another via a crossover branch pipe configured to allow continuous flow through the two backflow preventers. Each water pipe branch circuit may include a pump. The crossover branch allows water to flow through both backflow preventers, even when one pump is inoperative.

A backflow preventer assembly for a water management system includes a backflow preventer, an upstream shutoff valve, a downstream shutoff valve, a flow path, a pressure meter, and a flow meter. The upstream shutoff valve is positioned upstream from the backflow preventer. The downstream shutoff valve is positioned downstream from the backflow preventer. The flow path is defined at least partially through the backflow preventer, the upstream shutoff valve, and the downstream shutoff valve. The pressure meter includes a pressure sensor. The pressure sensor is in fluid communication with the flow path. The flow meter includes a flow sensor. The flow sensor is in fluid communication with the flow path.

A data collection device and method for determining a backflow condition in a water distribution system. The data collection device receives a first data communication from a first node, the first data communication indicating a first possible backflow condition at the first node. The data collection device receives additional data communications from one or more second nodes, the additional data communications indicating backflow conditions at the second nodes. The data collection device aggregates and analyzes the first data value and the additional data values and determines that an actual backflow condition exists based on the aggregated data values and a known relationship between the first node and the second nodes. The data collection device may then perform action(s) in response to determining the backflow condition, such as reporting the backflow condition, requesting updated reporting from the nodes, closing appropriate valves, initiating pumps to increase water pressure, flushing the system, etc.

The invention relates to a water-saving device which is fully automated and comprises a complete electronic control system, the possibility of connection to the aqueduct supply network and a hydraulic generator for saving energy. The device according to the invention communicates with a modular system that optionally reduces the water flow of the shower to 50% and diverts the other 50% to the storage tank, by means of the electronic interface. The device according to the invention is applicable in the construction industry.

A test cock is configured to connect to a test cock port. The test cock includes a body portion defining a flowpath between a distal end and a proximal end. The test cock includes an intake stem at the proximal end that has external threads to connect the test cock to the test cock port. The intake stem defines an intake opening connected to the flowpath, the intake opening having a non-circular shape, such as a hexagonal shape. The test cock also includes an extraction tool having an end forming the non-circular shape of the intake opening, the end being sized to fit within and engage the intake opening.
