scope:

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.

The macerating system is comprised of three major components:

(a) a container that houses the operating mechanisms;

(b) a pressure chamber that automatically or manually activates and deactivates the induction motor; and

(c) an induction motor that drives the shredder blades and pump assembly, which is permitted to be combined into a single unit.

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.
