What is the maximum discharge per flush allowed for flushometer type urinals?

1. 0.5 gallons per flush

2. 0.8 gallons per flush

3. 1.0 gallon per flush

4. 1.2 gallons per flush

The correct answer is: 1.0 gallon per flush

The maximum discharge per flush allowed for flushometer type urinals is 1.0 gallon per flush. This standard is established to promote water conservation while still ensuring adequate performance for sanitation needs. Flushometer toilets and urinals are designed to provide a strong flush using a minimal amount of water, and 1.0 gallon per flush strikes a balance between efficiency and flushing capability. This limit helps to reduce overall water usage in plumbing systems, aligning with environmental considerations and regulatory guidelines aimed at responsible water usage. Furthermore, the effective flushing action of a 1.0-gallon discharge helps maintain hygiene standards while keeping operational costs lower due to reduced water consumption.
