Frequently Asked Questions

Q. "Are real diamonds used in these faucets or their parts?"
A. Yes, but not the diamonds you would typically find in a jewelry store. Carbon (the source of diamonds) is taken and electrically charged. Then, using high amounts of pressure, fused to a ceramic plate, creating a diamond coating that is clear and nearly indestructible.

Q. "What is an InnoFlex waterway/supply line?"
A. Innoflex is a crosslink polyethylene (PEX-C) that is commonly used in the U.S. These new faucet waterways have a unique composition that makes it stronger than copper and easier to work with because it's flexible.

Q. "What are the new California Energy Commission water efficiency standards and how does this affect me?"
A. Effective January 1, 2016, certain plumbing fixtures will be required to comply with new California Energy Commission requirements for flow rate and water efficiency. Since the program began in 1976, it has continually worked to develop standards for energy- and water-using appliances and fixtures that will help Californians to conserve energy and water. To help the state deal with current and future drought conditions, only water-saving plumbing fixtures will be legally available for sale in California. Products like faucets, toilets, urinals, and shower heads are all affected by the new regulations.

  • Public lavatory faucets & aerators must have a maximum flow rate of 0.5 gallons per minute or less (at 60psi)
  • Kitchen faucets & aerators must have a maximum flow rate of 1.8 gallons per minute or less (at 60psi) - dual function faucets may have an optional temporary flow of 2.2 gallons per minute
  • Toilets must use a maximum 1.28 gallons per flush or less - or a dual-flush effective flush volume of 1.28 gallons per flush or less

What this means for the average consumer is that you can rest easy knowing that the product you're getting is compliant with the law - and will help you do your part to save water, our most precious natural resource. Additionally, it is important to note that current EPA WaterSense program requirements are not as stringent as the California Energy Commission requirements. Thus, not all WaterSense products may be compliant with the new laws in California. Please be sure to review the specifications of the product you're purchasing prior to placing your order as we cannot ship non-compliant products to our customers in California.
