Title:
Standard for Wall Carriers for Water Closets
Description:
This proposed change introduces a reference to a standard for wall carriers for water closets.
Problem
The National Plumbing Code of Canada (NPC) does not reference standards or provide specifications for wall carriers for water closets. As a result, it is unclear which wall carriers should be installed, where permitted.
The Code needs to reference a standard for wall carriers to ensure their proper selection and installation. Failure of non-compliant fixtures could lead to unsanitary conditions and harm to persons.
Justification
This proposed change includes a reference to ASME A112.6.1M-1997, “Floor-Affixed Supports for Off-The-Floor Plumbing Fixtures for Public Use,” a new standard for the performance of wall carriers for water closets. This requirement would address a gap in the NPC and prevent the installation of improper supports for water closets. Ensuring compliance with this standard is crucial to guarantee that the wall carriers installed meet the specified requirements mandated for their performance. This proposed change is intended to mitigate the risk of failure resulting from non-compliant fixtures, which could otherwise lead to unsanitary conditions and harm to persons.
PROPOSED CHANGE
NPC20 Div.B 2.2.2. (first printing)
[2.2.2.] 2.2.2. Fixtures
[2.2.2.1.] 2.2.2.1.Surface Requirements
[2.2.2.2.] 2.2.2.2.Conformance to Standards
[2.2.2.3.] 2.2.2.3.Showers
[2.2.2.4.] 2.2.2.4.Concealed Overflows
[2.2.2.5.] 2.2.2.5.Water Closets in Public Washrooms
[2.2.2.6.] ---Wall Carriers for Water Closets
[1] --)Where the wall carrier referred to in Sentence 2.3.3.8.(5) is attached to the floor, the wall carrier shall conform to ASME A112.6.1.M-1997, “Floor-Affixed Supports for Off-The-Floor Plumbing Fixtures for Public Use.”
Impact analysis
This proposed change mandates the installation of certified wall carriers for water closets. The proposed change will result in an increase in manufacturer testing and certification of products.
Although wall carriers for water closets have been in use for many years, some of these fixtures lacked certification and failed to meet the required standard. Opting to use certified products ensures consistent construction and proper sanitary practices and promotes safer usage of the fixture by the public.
Enforcement implications
No adverse enforcement implications are anticipated.
This proposed change clarifies the NPC requirements regarding the installation of wall carriers for water closets, fixtures that have been in use for many years.
Who is affected
Authorities having jurisdiction and Code users.
