What is the DFU value load factor assigned to a kitchen sink?

The Drainage Fixture Unit (DFU) value load factor assigned to a kitchen sink is 2. This value is specified in plumbing codes and guidelines, reflecting the average amount of wastewater that can be expected from a kitchen sink during peak usage times. The DFU is a crucial factor in plumbing design and helps determine the size of pipes and drainage systems needed to effectively manage the expected flow.

Understanding the DFU for various fixtures is important for plumbing professionals to ensure that systems are designed to handle the anticipated load without risk of backups or failures. In this context, a kitchen sink typically generates a moderate level of drainage demand, thus earning it the DFU value of 2, which balances efficiency and performance in plumbing systems serving kitchen areas.
