What is the water demand of a sink faucet according to plumbing standards?

In plumbing standards, the typical water demand for a sink faucet is set at a flow rate of 2.2 gallons per minute (gpm), which is often rounded up to approximately 2 gpm for common calculations and standards, particularly for residential fixtures. This flow rate is generally sufficient for daily activities, such as washing hands, brushing teeth, or filling small containers, while also promoting water conservation.

Choosing an answer aligned with common residential plumbing standards is important because it ensures that fixtures are efficient and compliant with modern water usage guidelines. The value of 2 gpm reflects the average requirement for standard sink faucets, balancing adequate flow with the necessity of conserving water resources. This measurement serves as a benchmark in plumbing codes and guidelines, shaping the design and installation of plumbing systems in homes and other buildings.
