ASSE 1014-2020, Performance Requirements for Backflow Prevention Devices for Hand-held Showers; ASSE 1020-2020, Performance Requirements for Pressure Vacuum Breaker Assemblies; and ASSE 1069-2020, Performance Requirements for Automatic Temperature Control Mixing Valves, have been designated as American National Standards by the American National Standards Institute (ANSI) and are now available for purchase.
I’m a solar engineer – not a mechanical one. That’s one reason that I found out the hard way that designing domestic hot water (DHW) production and distribution systems for multifamily buildings is a lot harder than designing a single-family residential system.
Every year, in the United States, thousands of people suffer serious scald injuries in showers or tub-showers after the hot water system temperature has been adjusted. These injuries can be prevented with the proper controls and adjustments of the maximum temperature limit-stop on each shower valve.
The group is now accepting applications as it reforms to develop a new white paper concerning recommended installation practices for residential tankless/on-demand water heaters to reduce the danger of scalds.
To achieve comfort and efficiency in a hot water distribution system, many plumbing engineers are incorporating hot water recirculation systems into their designs. But to reap the benefits of such a system, balancing valves must be incorporated into design considerations.
