The amount of sewer flow from a sanitary tee to a washing machine can vary depending on factors such as the specific plumbing configuration and the flow rate of the washing machine.
In a typical residential plumbing system, a sanitary tee is used to connect the washing machine drain hose to the sewer line. When the washing machine drains water, it discharges wastewater through the drain hose and into the sanitary tee, which then directs the flow into the sewer line.
The flow rate of a washing machine can vary depending on the model and settings, but it typically ranges from 10 to 20 gallons per minute (gpm). However, it's important to note that the flow rate can be affected by factors such as water pressure, the size of the drain pipe, and any potential restrictions or clogs in the plumbing system.
To ensure proper drainage and prevent issues like backups or overflows, it is important to ensure that the plumbing system is designed and configured appropriately. Consulting a professional plumber or adhering to local plumbing codes and regulations is recommended for proper installation and sizing of the drainage system for a washing machine.
