ANSI/ASSE (Plumbing) 1024-2004

ANSI Approved - 2004

This standard applies only to the type of backflow preventer identified as a dual check backflow preventer. This device consists of two (2) independently acting check valves, internally force loaded to a normally closed position, designed and constructed to operate under intermittent or continuous pressure conditions. The purpose of the dual check backflow preventer is to keep polluted water from flowing back into the potable water system, when pressure is temporarily higher in the polluted part of the system than in the potable water piping. The devices covered by this standard are intended to protect the potable water supply from low hazard pollution at residential service lines and individual outlets. These devices are intended for cold water service under continuous or intermittent pressure conditions. Usage with hot water is limited to the temperature specified by the manufacturer.
