![]() Individual shower and tub-shower combination valves shall be balanced-pressure, thermostatic or combination balanced-pressure/thermostatic valves that conform to the requirements of ASSE 1016 or ASME A112.18.1/CSA B125.1 and shall be installed at the point of use. The 2012 IPC has the following shower valve temperature requirement:Ĥ24.3 Individual shower valves. This is one of the most common misinterpretations. #Open start tap in simply fortran codeThe code gives us temperature limitations for various plumbing fixtures like showers and bathtubs (a maximum of 120☏), and this is often misinterpreted as a maximum temperature setting for the water heater thermostat or the storage temperature. If any one of the links in the chain fails there could be problems. So, it is important for a domestic hot water system to be designed for the intended application, installed in accordance with the design and maintained in accordance with the design. From my attendance at the code hearings over the years, mandating temperatures can increase costs and has been seen as limiting design options. The model codes list maximum hot water temperatures that can be delivered from various fixtures, but the storage and distribution temperatures have historically been left unaddressed in the plumbing codes. #Open start tap in simply fortran manualThe label also informs you that there are temperature limiting devices available and to refer to the installation and operation manual for more information.ĭomestic hot water storage and distribution temperatures are often one of the most misunderstood areas of the plumbing codes. The warning labels simply notify the owner or tenant that water temperatures in excess of 125☏ can cause serious injuries and death and that children, the elderly and disabled people are at most risk. Again, there is no such requirement in any model plumbing code addressing the hot water storage or distribution temperature from a water heater. There have been claims the maximum temperature is 125☏ based on the scalding temperature labels on the outside of most water heaters. There is no such requirement in any model plumbing code. There have been people claiming the maximum allowable storage temperature or thermostat setting on a water heater is 120☏). In fact, I am not aware of any model plumbing code that addresses minimum or maximum storage temperatures. There are a lot of people that think the model plumbing codes address domestic hot water system maximum storage temperatures. I have noticed a lot of misquoting of the plumbing codes when it comes to hot water system temperatures and hot water system controls. ![]()
