This is the fourth edition of CSA Z317.1, Special requirements for plumbing installations in health care facilities. It supersedes the previous editions, published in 1999, 1988, and 1978. This Standard is one of a series of Standards related to health care facility engineering.


This Standard specifies requirements for the following in health care facilities:

(a) hydraulic fire protection systems;

(b) pure water systems;

(c) drainage systems; and

(d) plumbing fixtures and fittings.

Note: See CAN/CSA-Z7396.1 for design, installation, certification, and maintenance requirements for non-flammable medical gas piping systems.

This Standard specifies minimum design, construction, installation, operations, and maintenance requirements in addition to the applicable requirements specified in

(a) the National Building Code of Canada;

(b) the National Plumbing Code of Canada;

(c) the CAN/CSA-B45 Series;

(d) the CAN/CSA-B64 Series;

(e) ASME A112.18.1/CAN/CSA-B125.1;

(f) ASME A112.18.2/CAN/CSA-B125.2; and

(g) CAN/CSA-B125.3.

This Standard is not intended to preclude the use of design concepts and the adoption of construction, installation, operations, and maintenance procedures more stringent than those specified in this Standard and in the documents listed in Clause 1.2.

Note: Water quality and conservation efforts involve protection of public health and the rational use of water from intake to tap. Such efforts include educating the consumer, appropriate water treatment, verification of drinking water quality, and appropriate operation and maintenance of storage and distribution systems. Optimal plumbing design and installation can help health care facilities adopt water protection and water quality strategies that preserve natural resources and the ecosystem as a whole.

This Standard applies to Class A-1, A-2, B, and C health care facilities.

Note: Some requirements may be waived for smaller Class C health care facilities as determined by the application of engineering principles and in consultation with the administrator and the authority having jurisdiction.

The requirements of this Standard apply to the retrofitting of existing systems when

(a) an existing health care facility is

    (i) extended; or

    (ii) subject to material alteration or repair; and
(b) the plumbing in existing facilities is adversely affected.

In CSA Standards, 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.
