The value of fixture units assigned to a 1 1/2" vent pipe is indeed 10 fixture units. This value is based on plumbing code guidelines that assess the capacity of vent pipes in relation to their size, which influences their ability to handle the necessary atmospheric pressure balance and venting required for various fixtures.

For a 1 1/2" diameter pipe, the established unit value reflects its capability to adequately vent a certain number of plumbing fixtures without risking siphonage or back-pressure, which can affect drainage. This rating ensures that the plumbing system operates efficiently and helps prevent issues such as odors or gases from escaping into living spaces.

Understanding fixture units is crucial for sanitary piping design, as it allows plumbers to correctly size drainage and vent systems to meet the demands of the connected fixtures, maintaining compliance with local plumbing codes and standards.
