| − | Why is there Lead in underground brass?
| |
| − | The main reason lead is in brass is to make the brass pressure tight. In the foundry process lead is the last element to solidify and therefore seeks and fills the microscopic voids (porosity) in the brass.
| |
| − | Lead also acts as a lubricant during the machine operation allowing for
| |
| − | easier machining and longer tool life.
| |
| − | Lead also gives brass ductility so that it bends before it breaks.
| |
| | | | |
| − |
| |
| − | What does No-Lead mean?
| |
| − | The Safe Drinking Water Act (SDWA) defines No-Lead or Lead Free brass as a weighted average Lead content ≤.25% for wetted surfaces
| |
| − | Federal Law 111-380 will eliminate brass products from the Water Works industry which do not satisfy the .25 ppb or less wetted surface requirements.

| |
| − | What will be replacing Lead?
| |
| − | Bismuth and/or Selenium are added to copper, tin and zinc and react similar to lead in the brass although not identical.
| |
| − | No-Lead brass will have trace amounts of Lead less than or equal to .25 of one percent by weight.

| |
| − | Besides Lead, what differences are there between Leaded and No-Lead brass?
| |
| − | You will not see a physical difference between Leaded and No-Lead brass
| |
| − | other than a manufacturers mark on each component that touches water.
| |
| − | Most manufacturers will designate No-Lead brass with a cast ―NL‖ on each
| |
| − | component.
