Scope:

Note: This notice of intent was withdrawn by the responsible SDO on February 27, 2024. Direct-type boiler and chiller fill valve assemblies with integral backflow preventer and system pressure regulator are used to control the inflow of water into heating and cooling systems to ensure sufficient system pressure. Devices protect the potable water supply against backflow due to backpressure and backsiphonage.

Project need:

There is a recognized ORD (ASSE ORD LEC 2009) in Canada and an LEC 2009 for the US. Per SCC ORD’s must be converted into a National standard within five years. Currently there is not a national standard for these devices. This standard meets the needs of stakeholders::Architects, Plumbing contractors, Codes officials, Manufacturers, plumbing installers, plumbing engineers and specifiers
