What is the load value in water supply fixture units for hot water in a kitchen sink faucet for private use?

The load value for hot water in a kitchen sink faucet for private use is established at 1 water supply fixture unit. This value is part of the plumbing code and is used to determine the demand on the water supply system. The fixture unit is a standardized measure that helps plumbers calculate the overall load on the system based on the number of fixtures and their usage patterns.

A kitchen sink is typically used for domestic purposes, and its water supply demand is relatively low compared to other fixtures in a plumbing system. The value of 1 fixture unit accurately reflects the average usage for typical residential kitchen sinks, allowing for effective sizing of water supply pipes and ensuring adequate water pressure is maintained throughout the system.

Higher values associated with other options would apply to fixtures with more significant load requirements, such as bathtubs, showers, or commercial-grade faucets, which necessitate a more robust supply system. Understanding these load values is crucial for proper plumbing design and installation.
