California introduces new water-saving flow rate requirements

Due to the severity of California's drought, Governor Edmund G. Brown Jr. has signed an executive order in April 2015, authorising the California Energy Commission to launch new water-saving standards for appliances with immediate effect.

New flow rate requirements in California:
  1. Residential lavatory faucets: flow rate shall not exceed 1.2 gallons per minute
    (NEW!!, was 1.5gpm before, according to Calgreen)
    Note: For residential lavatory faucets, the max. flow rate at 60 psi has to be lowered from 1.5gpm max. to 1.2gpm max. Furthermore compliance with EPA Watersense (min. 0.8gpm @20 psi and max. 1.5gpm @60 psi) is still required by Calgreen codes. While a NEOPERL® PCA® aerator can manage this balancing act, restricted aerators (flow class T1.5gpm or diffuser 1.5gpm) cannot be used any longer in California.
  2. Kitchen faucets: flow rate shall not exceed 1.8 gallons per minute (default setting); possibility to temporarily increase to 2.2 gallons per minute to fill pots and pans
    Note: was defined by the Calgreen program already; NEOPERL® Ecobooster being a perfect solution.
  3. Public lavatory faucets: flow rate shall not exceed 0.5 gallon per minute
    Note: identical to existing U.S. requirement.


The grace period granted for conversion is very short. Furthermore, it does not only apply to new buildings: the sale of non-compliant products is prohibited as of January 2016, regardless of the manufacturing date.
