The gallons per minute (GPM) capacity of a 4-inch drain can vary based on factors like the slope of the pipe and the type of fluid being drained. Generally, a 4-inch drain can handle approximately 40 to 50 GPM for wastewater. For precise calculations, it's important to consider the specific application and local Plumbing codes.
