BCAB #1383 - Pipe Sizes for Private Use Plumbing Fixtures, Subsection 6.3, B.C. Plumbing Code
March 14, 1995
Re: Pipe Sizes for Private Use Plumbing Fixtures, Subsection 6.3, B.C. Plumbing Code
The project in question is a new X-Ray laboratory in an existing building.
Reason for Appeal
Subsection 6.3. governs pipe sizing for potable water distribution systems. Pipe size is based on the number of fixture units assigned to a fixture by Table 6.3.A. and different fixture unit values are assigned based on private or public use of the fixture. Private use is defined in Part 1 as "...plumbing fixtures in residences and apartments, in private bathrooms in hotels and hospitals, in restrooms in commercial establishments containing restricted use single fixtures or groups of single fixtures, and to similar installations where the fixtures are intended for the use of a family or an individual."
The appellant contends that the sinks and hose bibbs in question are restricted to use by individual technicians operating the equipment in x-ray, ultra-sound and dark rooms and are for private, not public use.
Building Official's Position
The building official interprets "private use" to be fixtures installed in bathrooms for the use of a family or one individual only. Fixtures for the use of one or two persons with specific training or duties (technicians) does not meet the intent of the code definition of "private use".
Appeal Board Decision #1383
The word "private" in Tables 6.3.A. and 6.3.B. is not in italics and, therefore, does not necessarily carry the defined meaning from Part 1. The Board considers that the term "private" in these Tables means low frequency of use, similar to that of a private dwelling. The term "public" refers to the higher frequency of use commonly found in commercial, industrial or institutional occupancies. It is the determination of the Board that the fixtures (sinks and hose bibbs) in question should be considered "private" because the frequency of use is similar to that in a private dwelling.
