What is the required flow rate for a water supply outlet providing water to a dishwasher?

The required flow rate for a water supply outlet providing water to a dishwasher is established based on the performance needs of modern dishwashers. A flow rate of 2.75 gallons per minute ensures that the dishwasher has enough water to effectively clean dishes during its cycles.

Modern dishwashers are designed to operate efficiently and require a specific amount of water to function optimally. The 2.75 gallons per minute standard meets this requirement, allowing for adequate rinsing and washing without compromising the performance of the appliance. This flow rate also considers factors such as the typical duration of the wash cycles and the volume of water needed to adequately fill the dishwasher during operation.

Dishwashers that are installed with insufficient flow rates may struggle with cleaning effectiveness, potentially leading to unsatisfactory results and increased operational times. Ensuring the water supply meets this flow rate standard as outlined by the International Residential Code (IRC) helps in maintaining appliance efficiency and longevity.
