individual water supply
A specifically designed water distribution system where one or more pumps are operated in the service hot water piping to circulate heated water from the water-heating equipment to fixture supply and back
circulation hot water system
A water distribution system where every water distribution pipe is interconnected to provide two or more paths to each fixture pipe.
gridded water distribution system
A water control or shutoff component in the water supply system piping that, when adjusted for maximum flow, does not restrict the flow path through the component’s closure member.
full-open valve
The principal pipe artery to which branches are connected.
main
A measuring device used to collect data and indicate water usage.
meter
Water that is NOT safe for drinking, personal, or culinary utilization.
nonpotable water
A water supply pipe for public utilization controlled by public authority.
public water main
An impairment of the quality of potable water that does not create a hazard to public health but adversely affects the aesthetic qualities of such potable water for domestic use.
pollution
Water free from impurities present in amounts sufficient to cause disease or harmful physiological effects and conforms to the bacteriological and chemical quality requirements of the Public Health Service Drinking Water Standards.
potable water
A mechanical fitting that joins pipes or tubes and achieves a seal by mating the pipe or tube into the fitting.
push-fit fitting
A valve or faucet that closes automatically when released manually or is controlled by a mechanical means for fast-action closing.
quick-closing valve
Any pressure less than that exerted by the atmosphere.
vacuum
A pressure-actuated valve held closed by a spring or other means, designed to relieve pressure automatically at the pressure at which such valve is set.
pressure relief valve
A combination relief valve designed to function as both a temperature relief and a pressure relief valve.
temperature and pressure relief (T&P) valve
A temperature-actuated valve designed to discharge automatically at the temperature at which such valve is set.
temperature relief valve
Containing not more than 0.2-percent lead.
lead-free solder and flux
A permanent mechanical joint incorporating an elastomeric seal or an elastomeric seal and corrosion-resistant grip ring, made with a pressing tool and jaw or ring approved by the fitting manufacturer.
press-connect joint
Any physical connection or arrangement between two otherwise separate piping systems, one containing potable water and the other either water of unknown or questionable safety or steam, gas, or chemical, allowing flow from one system to the other.
cross connection
Any heating appliance or equipment that heats potable water and supplies such water to the potable hot water distribution system.
