During the 19th and early 20th century lead was widely used in major U.S. cities for water pipes because of its durability and malleability. Lead pipes were eventually superseded by galvanized steel and copper, and copper pipe became the predominant material selected for domestic water service and distribution in post-World War II residential construction.
Lead contamination was the top source of lead-related health issues before the hazards of ingesting it were known. The cause was pipe corrosion and erosion, and it raised stillbirth and infant mortality rates. Other plumbing or pipe problems are much easier to spot, but if you?re not testing for lead in your water, you?ll never know it?s there. You can find general information about lead contamination and how to test for it on the EPA?s website.
If you have lead in your water, it?s generally because of lead-based solder which was the primary material to join copper pipes together, a service line pipe from your house to the city or town water main made out of lead, and brass or chrome-plated brass faucets. In 1986, Congress put and end to the use of lead solder with over 0.2% lead in it. The lead in faucets, pipes and every other plumbing material was not allowed to exceed 8.0%.? ?Lead-free? brass legally can can?t have than 8% lead in it and plumbing systems installed prior to the 1986 legislation can possibly contain higher levels of lead.
Water lines from the city or town water main to a home or building?s water system may be a lead pipe in older structures. If you or a previous owner of the structure had your plumbing system upgraded since 1960, it?s probably composed of galvanized pipe. Galvanized pipe doesn?t need lead solder to be joined. Faucets need to be checked for brass or chrome-plating, you?re the original manufacturer, a local hardware store, or a licensed plumber should be able to tell you if yours contain either.
Once installed, epoxy pipe lining is a barrier to prevent lead leaching from your pipes into your drinking water. The epoxy lining prevents the water going through the pipe from coming into contact with the metal of the pipe, the chemical reaction that creates pipe corrosion is prevented. Epoxy pipe lining will prevent lead and other metals (from your pipes) from getting into your water. The lining also prevents other poor water quality issues, for example: red, brown, blue or yellow water, zinc or iron leeching from galvanized pipes into your water, causing a metallic taste, and bacteria can cause terrible tasting or smelling water.
Epoxy lining of pipes is not a new technology, just a relatively unkown one. But it?s not unproven ?both the U.S. Navy and U.S. Army Corps of Engineers have tested and approved the use of epoxy pipe lining to prevent lead and other contaminants from leaching into drinking water.

There is no need for health concerns when it comes to epoxy lining your pipes, CuraFlo?s epoxy, CuraPoxy?, is certified to meet ANSI/NSF Standard 61 – the U.S. government standard for safe potable (drinking) water. ANSI/NSF Standard 61 certification means that something is certified safe to be used in potable water pipes at temperatures up to 180? Fahrenheit or 82.2? Celsius. CuraFlo?s epoxy pipe lining process protects you from lead (and other metals) in your pipes leaching into your water by preventing these metals from leaching into your water.
