2021 International Plumbing Code
A modification to Section 202 (Definition of Public and Private) states that the definitions of “public” and “private” are simplified to make a clearer distinction as to which plumbing fixtures are intended to be configured for public use.
The definition of “public” is aligned with that of standards ASME A112.18.1, Plumbing Supply Fittings, and ASHRAE 90.1, Energy Standard for Buildings, to minimize the number of lavatory fixture fittings (faucets) that must comply with the code’s public use requirements for 1) discharging only tempered water and 2) having a flow rate of not greater than 0.5 gpm.
Public lavatory faucets are the only plumbing fixtures required by the code to discharge tempered (between 85 and 110°F) water. The revised definitions have little, if any, impact on public lavatories. However, as the terms “public” and “private” are used throughout the code for purposes beyond identifying lavatory types, the revised definitions could give new meaning to other code sections even though the approved proposal may not have intended to change the meaning in those contexts.
