***Brass solenoids are not lead free and it is illegal to use them in potable services
in the United States such as drinking water, handwashing, food preparation, and
dishwashing. However, brass solenoids may be used as a replacement component in
a lead free Watts ACV main valve, as the wetted surface of a lead free Watts ACV main
valve including installed brass solenoids contains less than 0.25% of lead by weight.
