The UPC letters are an acronym for the "Uniform Plumbing Code". This code is a listing of particular specifications and guidelines set forth by the American National Standards Institute (ANSI) which is designed to assure that products are safe for the consumer and the environment by meeting all established national and international criteria. The "c" in cUPC means that the product meets the Canadian as well as the American plumbing standards. Most Sir Faucet products are, or are in the process of becoming, UPC/cUPC certified.
Referred to as NSF, this organization changed its name to NSF International (from National Sanitation Foundation) in the 1990s. It is an independent public health and safety organization whose purpose is to develop public health standards and certifications which protect food, water, consumer products and the environment. As an independent, accredited organization, they test, audit and certify products and systems, as well as provide education and risk management. Most Sir Faucet fixtures comply with NSF standards.
WaterSense is a partnership program of the EPA which seeks to protect the future of our nation's water supply by offering people a simple way to use less water with water-efficient products. WaterSense labeled products are backed by independent, third–party testing and certification, and meet the EPA’s specifications for water efficiency and performance. These products are certified to perform as well or better than their less efficient counterparts, and to be 20 percent more water efficient than average products in their category. Several Sir Faucet models carry the WaterSense label.
The Safe Drinking Water Act (SDWA), enforced by the Environmental Protection Agency (EPA), has established standards to protect the U.S. public drinking water. Guidelines pertaining to plumbing fixtures require materials and fittings on such devices to be free of lead. All Sir Faucet products are compliant with the SDWA.
