Special requirements for plumbing installations in health care facilities
This Standard addresses the special requirements of plumbing systems pertinent to the design,
construction, operation, and maintenance of health care facilities (HCFs). This Standard specifies
requirements for the following in HCFs:
a) water supply systems, including domestic cold water systems and hot water systems;
b) plumbing fixtures and fittings;
c) drainage systems;
d) monitoring and maintenance of water systems;
e) infection control;
f) catastrophic event planning;
g) specialized water systems (e.g., reverse-osmosis, deionized, distilled); and
h) hydraulic fire protection systems.
Note: Special requirements for plumbing systems apply in HCFs because of the need to protect occupants of the
facility and the adjacent surroundings from
a) infectious diseases;
b) hazards created by improper temperatures, leaks, and inadequate drainage; and
c) adverse conditions created by the failure or improper operation of plumbing systems.
This Standard supplements the relevant standards and other applicable requirements for plumbing
systems, fixtures, and fittings in general building applications.
1) Relevant plumbing standards for plumbing systems, fixtures, and fittings in general building applications
a) ASME A112.19.2/CSA B45.1;
b) ASME A112.19.1/CSA B45.2;
c) ASME A112.19.3/CSA B45.4;
d) CSA B45.5/IAPMO Z124;
e) CAN/CSA-B64 Series;
f) ASME A112.18.1/CSA-B125.1;
g) ASME A112.18.2/CSA-B125.2; and
h) CSA B125.3.
2) Applicable requirements for plumbing systems are also contained in the National Building Code of Canada
and the National Plumbing Code of Canada.
This Standard does not apply to medical gas systems.
Note: See CAN/CSA-Z7396.1 for design, installation, certification, and maintenance requirements for nonflammable
medical gas piping systems.
