Can Epoxy Lining Prevent Lead Contamination from Water Pipes
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 buildings and homes, the service line from the municipal water main to the house may be a lead pipe -- something you should definitely confirm. Unless your piping has been upgraded in the past 40 years, it is probably galvanized pipe (iron with a zinc coating) which does not require lead solder to join the pipe. You may already know if your faucets are brass or chrome-plated, but if not, you might want to consult with a licensed plumber or take them with you to a local hardware store. CuraFlo??s website offers a brief history of lead materials in water pipes.
If your pipes are the source, epoxy lining will prevent lead leaching into your drinking water. Because the epoxy lining creates a barrier between the metal pipe and the water coming in contact with it, it stops the chemical reaction that causes corrosion. It eliminates and prevents from reoccurring, leaching of lead and other metals into the water, as well as a host of other poor water quality issues such as: discolored water (red, brown, blue or yellow), metallic taste (caused by zinc or iron leeching in galvanized pipes), and water odor or bad taste (caused by bacteria).
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. Links to their reports are available at http://curaflo.com/CuraFlo/ResourceCenter.
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.
