A shampoo sink in a beauty shop has a fixture unit rating of ___________.

In the context of plumbing codes, fixtures are assigned unit ratings that help determine their impact on the overall plumbing system, especially when calculating flow rates and demand on the system. For a shampoo sink in a beauty shop, the fixture unit rating is established based on its expected usage pattern.

The shampoo sink is primarily used for washing hair, which typically involves a significant flow of water for a short duration. Plumbing codes generally assign a fixture unit rating of 2 to shampoo sinks. This rating reflects the average demand placed on the plumbing system when the fixture is in use, balancing the need for adequate water supply while considering the frequency and duration of its use in a commercial setting like a beauty shop.

Understanding this rating helps ensure that the plumbing system is adequately sized and can handle the water demand without risk of overloading or inefficiencies.
