• Listings-Certification FAQ's

    Here you'll find answers to some of the most frequently asked questions; check back often as we'll make updates as new questions arise.

    The new standard does not apply to pipes, pipe fittings, plumbing fittings or fixtures that are used exclusively for non-potable services such as manufacturing, industrial processing, irrigation, outdoor watering, or any other uses where water is not anticipated to be used for human consumption. The law also specifically excludes toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are 2 inches in diameter or larger.

    Yes, there are three options:

    • Cold water applications: an end-use that is intended to result in continuous exposure to water at ambient temperature. Products are tested for an end-use temperature of 73 ± 4°F.

    • Domestic hot water applications: an end-use that is intended to result in continuous or intermittent exposure to water above that is above ambient, such as a part of the hot side of a residential piping system. Products are tested for an end-use temperature of 140 ± 4°F.

    • Commercial hot water applications: an end-use that is intended to result in continuous or intermittent exposure to water that is above ambient and domestic hot conditions, such as a part of the hot side of a commercial piping system. Products are tested for an end-use temperature of 180 ± 4°F.

    The Reduction of Lead in Drinking Water Act goes into effect on January 4, 2014. However, new lead content restrictions are already in effect in California and Vermont since January 1, 2010, Maryland since January 2012, and Louisiana since January 2013. It will be against the law to sell or install products for use in potable water applications that are not lead free nationally as of January 4, 2014.

    The Reduction of Lead in Drinking Water Act is a federal law that amends the Safe Drinking Water Act (SDWA) and sets new, lower standards for the amount of lead permissible in plumbing products that come into contact with potable (drinkable) water. The U.S. Environmental Protection Agency (EPA) has primary responsibility for interpreting the SDWA with individual states using health or plumbing codes or other standards consistent with the SDWA and EPA regulations to enforce those standards.

    Yes and No. Yes, if the modification directly affects the functionality of the valve. No, if for example, you are adding an external item such as a Babbitt sprocket to a UL listed valve for remote operation. UL valves can be repaired, provided the repair parts are obtained directly from the manufacturer.

    Fire Protection valves are used in a fire protection system such as a sprinkler system. It should not be assumed that a fire protection valve is fire safe or UL listed.

    A Fire Safe valve will be designated by an “FS” in the figure number (ex. F-510-CS-R-66-FS). Fire safe means that the valves have been designed and tested to meet industry requirements for performance after having been subjected to extreme heat, such as would happen if they were involved in a fire.

    A UL Listed valve will have the UL symbol stamped on the valve. UL listing means the valve has been tested and approved by Underwriter Laboratories for the service listed. Only valves with the UL stamp are UL tested.
