As of March 2002, the valves used in residential plumbing systems continue to be made with 5 to 7 percent leaded brass
Before 1994, a significant component of most commercially available submersible water pumps was a pump housing made from sand-cast leaded brass
The lead- free brass leached approximately 100 times lower levels of lead than the leaded brass
