Epoxy Pipe Lining Can Prevent Lead Contamination

By Dr. Dave Dunn

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.

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.

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.

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.

government?s highest stadard for safe drinking water: ANSI/NSF Standard 61. ANSI/NSF Standard 61 certification means CuraPoxy is certified for safe use in drinking water pipes carrying water up to 180? Fahrenheit or 82.2? Celsius. The proprietary epoxy and epoxy pipe lining process CuraFlo uses will protect you from lead and other metals in your pipes that may be leaching into your water now or might in the future, by creating a safe barrier between them and your water. - 15431
