Working Groups

  • Hot Water Temperature Control
    Scope: The development of consensus requirements for the control of hot water in a water distribution system. The standard should identify the temperature limitations, range of temperature, and acceptable means of controlling the temperature of hot water. Flexibility of design will be included in the design requirements.
  • Water Pipe Sizing
    Scope: The development of consensus requirements for the sizing of various water distribution systems. The standard should identify the various methodologies for sizing a water distribution system, identifying the limiting parameters based on the selected method. Specific design limitations should be quantified, including flow velocity, flow rates for various fixtures, and pressure limitations.
  • Venting Systems
    Scope: The development of consensus requirements for the various venting methods that can be used in a plumbing system. The standard will identify all of the venting methods that have proven to be successful in a plumbing drainage system plus the method for engineering the design of a venting system.
