Topic areas for proposed changes to the USHGC include: applicable standards for hydronic system components; heat pumps; dual purpose water heaters; protection of potable water supply and applicable standards; pressure testing; discharge piping; expansion tanks and sizing; oxygen permeation; joining methods and connections for hydronic distribution piping and tubing; safety devices; radiant wall and ceiling panels; tube fasteners; tracer wires; solar photovoltaic systems; and applicable equipment standards.

Topic areas for proposed changes to the USPSHTC include: flood resistant design and construction for flood hazard areas; applicable material standards for building supply, water distribution, and circulation system piping and fittings; water supply and circulation system pipe joints and connections; tracer wires; pool lifts and accessibility; slip-resistant walkway surfaces; islands; lazy rivers; bridges; vanishing edge pools; beach entry pools; ventilation of indoor aquatic facilities; water chemistry; heaters; zero-depth entry pools; signage; secondary entrapment prevention.

IAPMO urges its members and other interested parties to get involved in the code development process to ensure effectiveness in preserving the public health, safety and welfare through fair and balanced development of the Uniform Codes. Installers, plumbing and mechanical officials, the construction industry, engineers and manufacturers all benefit from a cooperative effort in developing codes.
