Clothes washers in a group of three or more have an individual fixture unit rating of?

• A. 3
• B. 4
• C. 6
• D. 5

Answer: (C)

The individual fixture unit rating for clothes washers in a group of three or more is assigned as 6. This means that when considering clothes washers in a multi-unit installation, each washer contributes a higher load to the overall plumbing system, reflecting its demand on the water supply and drainage systems. The rating takes into account the likelihood that multiple washers may operate simultaneously, influencing the design and sizing of pipes and any associated drainage. In plumbing calculations, this higher rating helps ensure that the plumbing system can handle potential peak usage and that there is adequate capacity for water distribution and waste removal, which is critical in residential and commercial settings where such appliances are commonly used. Understanding fixture unit ratings allows for better planning and installation of plumbing systems to prevent issues related to inadequate flow or drainage capacity.
