    Reduced pressure zone device connected to a fire hydrant. A reduced pressure zone device (RPZD, RPZ, or RPZ valve) is a type of backflow prevention device used to protect water supplies from contamination. RPZDs may also be known as reduced pressure principle (RP), reduced pressure principle backflow prevention devices, [1][2] reduced pressure ...

    en.wikipedia.org/wiki/Washing_machine

    A very effective precaution is to install a shutoff or isolation valve which stops any water from being supplied, except when a washing machine is actually operating. The simplest method is to manually open and close the hot and cold water shutoff valves (traditionally globe valves) behind the washing machine, each time it is used. This method ...

    A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze ...

    en.wikipedia.org/wiki/Tap_(valve)

    Turning a valve knob or lever adjusts flow by varying the aperture of the control device in the valve assembly. The result when opened in any degree is a choked flow . Its rate is independent of the viscosity or temperature of the fluid or gas in the pipe, and depends only weakly on the supply pressure , so that flow rate is stable at a given ...
