What is the maximum flow rate for a public lavatory when the water pressure is 60 lbs. per sq. in.?

The maximum flow rate for a public lavatory at a water pressure of 60 lbs. per sq. in. is typically set at 0.5 gallons per minute. This standard is often referenced in plumbing codes and regulations to ensure water conservation while still providing adequate functionality for public facilities.

Public lavatories are designed to be efficient and minimize water waste, and the flow rate of 0.5 gallons per minute strikes a balance between meeting user needs and conserving water. Additionally, this flow rate is adequate for handwashing and other essential functions typically performed in public bathrooms.

Understanding the specifics of these standards is important for plumbing contractors, as they help maintain compliance with both local and national plumbing codes aimed at promoting sustainability and proper resource management.
