Apparatuses regulate the flow of fluids, such as, for example, water or other like fluids, through pipes. The apparatuses comprise a poppet valve having a spheroid-shaped valve portion and one or more shims for adjusting effective spring length during use thereof. Specifically and without being bound by theory, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid, allowing more accurate water meter measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for regulating the flow of fluids within a pipe are further provided.

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.

An embodiment of a fluid valve includes a substantially flat face plate, a receptacle, a cavity, and a valve assembly. The receptacle is disposed in the face plate and has at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-fluid-dispensing device. The cavity has a front end in fluid communication with the receptacle, and has a rear end. And the valve assembly is disposed in the cavity, includes a first sealing ring, is configured to form a seal by urging the sealing ring against the rear end of the cavity in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle, and is configured to allow fluid to flow into the rear end of the cavity in response to the valve-opening-and-fluid-dispensing device being disposed in the receptacle.

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 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 decorative air gap cap cover is disclosed. An example embodiment can include: a hollow decorative shell configured with upper and lower interior regions relative to an internal ridge, the internal ridge configured to rest on an upper surface of a ring gasket installed around an air gap cap, the air gap cap being captured within the upper and lower interior regions of the hollow decorative shell; a fluid channel within the hollow decorative shell configured with an entry opening above the internal ridge and an exit opening below the internal ridge, the exit opening terminating at an exit port of the hollow decorative shell; and a top vent hole providing an air channel between the upper interior region and the exterior of the hollow decorative shell. An embodiment can also include an auxiliary fluid channel configured with an entry opening below the internal ridge and an exit opening below the internal ridge.

A sanitary equipment with a water supply system, a water route system, and a hand washing table are provided. The sanitary equipment includes a machine having a machine water outlet; a movable hand washing table pivoted on the machine and located below the machine water outlet, the movable hand washing table being capable of opening or retracting with respect to the machine; and a water route system disposed in the machine and connected to the machine water outlet to discharge potable water and non-potable water from the machine water outlet.

A shower system includes a water supply conduit, a reservoir, and a valve actuator. The reservoir is fixedly coupled to the water supply conduit such that the reservoir and the water supply conduit are fluidly coupled. The valve actuator is configured for actuation between a first position in which water is supplied from the water supply conduit and a second position in which water is supplied from the reservoir. In some implementations, the shower system further includes a showerhead that is fluidly coupled to the water supply conduit and the reservoir such that water may be supplied from either the water supply conduit to the showerhead or from the reservoir to the showerhead.

Fluid detection systems and methods using the same are disclosed. In embodiments the fluid detection systems include a sensor module and an electronics module. The sensor module includes a sensor housing that includes a liquid flow path and a sensor element disposed around at least part of the liquid flow path. The sensor element can detect a capacitance of the liquid flow path and provide a sensor signal to a controller in the electronics module. The electronics module can determine a detected capacitance in the liquid flow path based at least in part on the sensor signal, and can determine whether a wet event has occurred based on a comparison of the detected capacitance to a threshold capacitance. Methods using the fluid detection systems and fluid supply systems including the fluid detection systems are also disclosed.
