The primary material for water pipes in major U.S. cities, between the late 19th and early 20th centuries, was lead. Its durability and malleability made it a very popular choice for pipe material. Eventually galvanized steel and copper would replace lead, and copper pipe would eventually become the most popular material used in home water service and distribution in mid to late 20th century construction.
Pipe corrosion and erosion-caused lead contamination, was the top source of lead-related health issues before the hazards of ingesting lead were realized. Stillbirth and high infant mortality were two of the worst effects of lead ingestion. Many other plumbing or pipe problems are easy to detect by seeing or listening, but without specifically testing for it, there is no way to detect lead in your water. The EPA offers general information about lead contamination and how to test for it on its website.
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.
In older structures, lines from the city/town water main to the home or building may be a lead pipe . Unless your piping has been upgraded in the past 40 years, it is probably galvanized pipe which does not require lead solder for joining. Faucets should be checked to see if they are brass or chrome-plated, a licensed plumber should be able to tell you if they are. CuraFlo??s website offers a brief history of lead materials in water pipes.
If you have lead contamination from your pipes, epoxy lining can be your solution. Once installed it is a barrier to lead leaching into your drinking water. The epoxy lining prevents the metal of the pipe and the water flowing through from coming into direct contact. This prevents the chemical reaction that causes pipe corrosion. Epoxy pipe lining eliminates and prevents lead and other metals (from your pipes) leaching into the water, as well as a host of other poor water quality issues such as: water that?s red, brown, blue or yellow, zinc or iron leeching in galvanized pipes causing a metallic taste, and bacteria that causes bad tasting water or water that smells.
A relatively unknown technology, epoxy pipe lining is not a new technology, --in fact it?s well proven. The U.S. Army Corps of Engineers and U.S. Navy have both ested and approved the use of epoxy pipe lining to prevent contaminants, including lead, from leaching into drinking water. Their reports are published and links to them can be found at http://curaflo.com/CuraFlo/ResourceCenter. The epoxy used by CuraFlo in epoxy pipe lining, CuraPoxy?, is certified to meet the U.S.
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.
