Lead used to be a primary material for water pipes in major U.S. cities, until the early 1900?s. It was so heavily favored because of its durability and malleability. Galvanized steel and copper eventually replaced lead, and copper pipe became the most popular material used in home water service and distribution in post 1950 construction.
Lead contamination, caused by pipe corrosion and erosion, was the major source of lead-related health problems in the years before the health hazards of ingesting lead were fully understood. Two of the most serious health problems were stillbirth and high rates of infant mortality. Part of what did and continues to makes it so serious is that, unlike many other plumbing or pipe problems, there is no way to detect it without having your water tested. On its website, the EPA offers general information about lead contamination and how to test for it.
If you have lead in your water, it?s generally because of one (or more) of these: lead-based solder which used to be the primary way to join copper pipes, a lead service line pipe linking your house to the city or town water main, and brass (or chrome-plated brass) faucets. The U.S. Congress banned the use of lead solder containing greater than 0.2% lead in 1986. It also limited the lead composition of pipes, faucets, and all other plumbing materials to 8.0%.? As a result of this legislation, ?lead-free? brass legally can contain no more than 8% lead and plumbing installed before 1986 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.
The U.S. Army Corps of Engineers (http://www.wbdg.org/ccb/ARMYCOE/PWTB/pwtb_420_49_35.pdf) and the U.S. Navy (http://stinet.dtic.mil/cgi-bin/GetTRDoc?AD=ADA327758&Location=U2&doc=GetTRDoc.pdf) have documented their 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.
