What does Lead Free* mean?

You’ll notice that whenever we use the phrase, “Lead Free*”, an asterisk or other designation will immediately follow the phrase that refers to the following statement.

*The combined metal components of this product contacted by potable water contain less than one half of one percent (0.5%) lead by weight.

This statement addresses the fact that trace amounts of lead can be found in the castings and metal components that we use and therefore may be contained in the final product we produce. However, at this extremely low level of lead we are significantly below the current NSF/ANSI Standard 61 requirements for these products.

All model descriptions, metal nameplates attached to the product, box labels and master carton labels will utilize an “LF” prefix before the model number to designate Lead Free* product, Example: ½" LF 25AUB-Z3. The following photos illustrate examples of the LF markings on the nameplate and box label respectively.
