What is ASSE 1002-2015?

ASSE 1002-2015 is a professional technical standard that sets requirements and guidelines for the design, installation, and maintenance of water heater thermal expansion control valves. This standard was developed by the American Society of Sanitary Engineering (ASSE), an organization that focuses on providing standards and education for professionals in the plumbing industry.

The Purpose of ASSE 1002-2015

The main purpose of ASSE 1002-2015 is to ensure the safe and efficient operation of water heaters while preventing potential hazards caused by thermal expansion. Thermal expansion occurs when water is heated and expands, which can lead to increased pressure in the water heater system. If not properly controlled, this increased pressure can cause damage to the water heater, associated piping, and other connected fixtures.

Requirements and Guidelines

ASSE 1002-2015 provides specific requirements and guidelines for the design and installation of thermal expansion control valves in water heater systems. This includes determining the proper sizing and placement of the valve, as well as the necessary temperature and pressure settings. The standard also covers the materials and construction of these valves, ensuring they are durable and suitable for their intended use.
