The maximum flush volume allowed for a new urinal (other than wall-mounted) in California is generally:
a.0.5 gallon per flush
b.1.0 gallon per flush
c.1.6 gallons per flush
d.2.0 gallons per flush
Explanation
New urinals are limited to a maximum of 0.5 gallon per flush, with high-efficiency and non-water urinals using far less. This reflects both plumbing code and CALGreen water-efficiency goals. Choosing a compliant urinal is required for new commercial restrooms.
