ASME A112.3.4

Abstract

This Standard establishes physical, performance, and testing requirements applicable to macerating toilet systems and related components. Such systems are intended to collect waste from a single water closet, lavatory, and/or bathtub located in the same room, and grind and pump these macerated wastes to some point in the sanitary drainage system. <br>The macerating system is comprised of three major components: <br>(a) a container that houses the operating mechanisms; <br>(b) a pressure chamber that automatically or manually activates and deactivates the induction motor; and <br>(c) an induction motor that drives the shredder blades and pump assembly, which is permitted to be combined into a single unit. <br>The use of alternate materials or methods is permitted, provided it can be demonstrated that such alternatives comply with the performance requirements of this Standard.
