Can Epoxy Lining Prevent Lead Contamination from Water Pipes
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 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 your water is lead contaminated, it's most likely because of one or more of the following: lead service line pipe(s) connecting your house to the municipal water main, lead-based solder (used to join copper pipes), and brass or chrome-plated brass faucets. In 1986, Congress banned the use of lead solder containing greater than 0.2% lead, and restricted the lead content of faucets, pipes and other plumbing materials to 8.0%.? This so-called ?lead-free? brass can still legally contain up to 8% lead and plumbing systems installed prior to 1986 can contain high levels of lead from both plumbing components and lead solder.
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.
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.
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. - 17269
