Plumbing fixtures with pumped waste and macerating toilet systems

1.1
This Standard establishes physical, performance, and testing requirements applicable to plumbing fixtures with pumped waste, macerating toilet systems, and related components. Such systems are intended to collect waste from a single fixture such as a water closet, lavatory, shower, or bathtub and pump these wastes to some point in the sanitary drainage system.

1.2
The purpose of this Standard is to establish a generally acceptable performance standard for pumped waste systems, macerating systems and related components for directly affixed water closets and other fixtures designed for above the-floor or in-floor installations.

1.3
A water closet connects to a macerating toilet system. Macerating toilet systems collect the waste from a single water closet, plus a lavatory, shower, bathtub, or a combination of these in the same room. Macerating systems grind and pump these macerated wastes to some point in the sanitary drainage system.

1.4
Pumped waste systems consist of three major components:

(a) an automatic activation of the pumped waste system;

(b) a drainage connection to the pump; and

(c) a pump that pumps the waste to the gravity drainage system.

1.5
The macerating system comprises 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.
