Preface

This is the first edition of ASME A112.3.4/CSA B45.9, Plumbing fixtures with pumped waste and macerating toilet systems. This Standard supersedes ASME A112.3.4-2000, Macerating Toilet Systems and Related Components, and CSA B45.9-2002, Macerating Systems and Related Components.

Scope

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.

1.6
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.

1.7
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.8 Units of measurement
SI units are the units of record in Canada. In this Standard, the inch/pound units are shown in parentheses.

The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in non-conformance with this Standard.

All references to gallons are to U.S. gallons.
