Gas Fired Water Heater with Mixing Valve Piping

Elements

About this detail

This plumbing diagram details the piping layout for a gas fired water heater and a five hundred gallon storage tank mounted on concrete equipment pads. The natural gas supply feeds the water heater through a gas cock and a full size dirt leg, with a neutralization kit and a spill relief routed to a floor drain. A water heater circulator pump, flow switch, and temperature and pressure relief valve connect the tank and heater loop. Domestic cold water enters the system with a ball valve, check valve, strainer, and PT port. A thermostatic mixing valve tempers the output to one hundred thirty-one degrees Fahrenheit, supported by a domestic hot water return line maintained at one hundred twenty-two degrees Fahrenheit minimum with a circulator, balancing valve, and thermometers.
