What is the orifice size limit for a drinking fountain nozzle?

3/8 of an inch
1/2 of an inch
7/16 of an inch
5/8 of an inch

The correct answer is: 7/16 of an inch

The correct answer is that the orifice size limit for a drinking fountain nozzle is indeed 7/16 of an inch. This specification is established to ensure an appropriate flow rate for drinking water, providing a balance between accessibility and conservation. A smaller orifice would not allow adequate water flow, while a larger one could lead to waste and inefficient usage, compromising the intended design of the drinking fountain. Understanding these size limitations is critical for compliance with the Illinois Plumbing Code, which aims to ensure safe and efficient plumbing practices. The regulation concerning orifice sizes is designed to promote accessibility for all users while maintaining sanitary conditions and efficient water usage.
