An essential reference for anyone engaged in the plumbing materials and equipment industry.ASME A112.19.5 establishes criteria for those items of trim for water-closet bowls, tanks and urinals known as spuds, and flush valves. 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 non-standard features for use in low-consumption plumbing fixtures.

This publication is “harmonized” – developed in response to an industry request for a uniform standard that would be acceptable in both the United States and Canada. It offers comprehensive solutions applying to the design, construction, installation, performance, operation, inspection, testing and marking of these components used for plumbing purposes.

A112.19.5 is to be used in conjunction with components described in other volumes of the ASME A112 series. Careful application of these A112 standards will help users to comply with pertinent regulations, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed within these volumes.

Intended for manufacturers of plumbing materials and equipment to enhance water conservation and comply with jurisdictional regulation, plus governmental and other regulatory bodies.
