California Proposition 65 Warning Labels

The California Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as “Proposition 65,” requires manufacturers to provide a warning label on products that may contain chemicals on the State of California’s Prop 65 list. In August 2016, the Office of Environmental Health Hazard Assessment (OEHHA) adopted new Prop 65 regulations that become effective August 30, 2018. The new Prop 65 regulations include changes to the requirements for warning label language and use. These changes address not only the labeling of product packaging, but also the requirements for warnings on website landing pages and catalog pages used to sell products to consumers in California.

Delta®, Brizo® and Peerless® models that require the Prop 65 label are identified in the product list below, which also indicates the appropriate Prop 65 label for each product.

California Title 20 Water-Efficiency Standards

Due to severe drought, California Governor Jerry Brown mandated water restrictions in an Executive Order issued April 1, 2015. In the Order, the California Energy Commission (CEC) was charged with adopting emergency regulations establishing standards that improve the efficiency of water appliances, including faucets, toilets, urinal flush valves and shower devices available for sale in California.

The CEC’s water-efficiency standards, which are comparable to or lower than the applicable WaterSense® program standards, are noted below.

California Title 20 Water-Efficiency Standards FAQs

Important Note about Permitted Work
For permitted work, the application of the 1.8 gpm standard is driven by both the manufactured date and building permit application date.

According to the CALIFORNIA CODE OF REGULATIONS, TITLE 24, PART 2, Section 1.1.9, the standards approved by the California Building Standards Commission that are effective at the time an application for a building permit is submitted shall apply to the plans and specifications for, and to the construction performed under, that permit.


Per this requirement, 2.0 gpm showering products can only be installed after July 1, 2018 for permitted work if both the following criteria are met:

  • Products were manufactured prior to July 1, 2018
  • Building permit was submitted prior to July 1, 2018


All showering devices must meet the new 1.8 gpm standard if the device is manufactured after July 1, 2018 or the device is being installed where a building permit is obtained and the permit application was submitted after July 1, 2018.

For non-permitted work, compliance with the 1.8 gpm standard is driven by manufactured date only. The date of sale doesn’t matter.

Most Delta, Brizo and Peerless shower devices that comply with the 2.0 gpm standard have been converted to 1.75 gpm and are in compliance with the 1.8 gpm standard. This is a running change for most models with no change to model numbers. All 1.75 gpm products will be WaterSense® labeled and marked with a green sticker on the individual box and outer carton.
