Description

ANSI Approved – 2002Devices covered by this performance standard are designed primarily to supply water to floor drain traps which have infrequent use and in which water evaporation would allow sewer gas to enter the premises. The type of device covered by this standard is designed to supply water to a drain trap to provide and maintain its water seal using a supply from a fixture drainline, ballcock, or flushometer valve tailpiece or an electronic primer device. The rate of water flow to the trap shall be permitted to be fixed or adjustable. The devices are of four (4) types: (a) Those which are installed on waste line tail pieces from fixtures, such as lavatories, sinks and similar fixtures where grease is not normally generated; (b) Those which are used in conjunction with ballcock assemblies; (c) Those which receive flow from flushometer valves; and (d) Those electronics devices which discharge water automatically and which are upstream of the air gap or vacuum breaker.
