Can I still be sold plumbing fixtures that contain lead?
If you go to your local hardware store, no. Products sold in the US have to be lead free, since 1996


  In 1996 Congress further amended the Safe Drinking Water Act, requiring plumbing fittings and fixtures (endpoint devices) to be in compliance with voluntary lead leaching standards. The amendments also prohibited the introduction into commerce of any pipe, pipe or plumbing fitting or fixture that is not lead free.


Ebay is a bit of the "wild west", because you often have products sold direct to consumers from foreign countries (i.e. they bypass US regulations because they're sold and shipped from that country to you directly). It's easy to find Chinese or Indian products on there, and neither country has that prohibition against lead. So, yes, you probably need to screen on Ebay. If it's a serious concern for you, just buy from a US company or your local hardware store.
