Trim for Water-Closet Bowls, Tanks, and Urinals
This Standard establishes criteria for those items of trim for water-closet bowls, tanks, and urinals known as spuds, locknuts for spuds, flush valves, and flush elbows. Requirements for fill valves (ballcocks) are defined in ANSI/ASSE 1002.
This Standard does not address the compatibility of materials. Nothing stated herein shall preclude the production of special design flush valves with unique nonstandard features for use in low-consumption plumbing fixtures.
