How Safe is PEX Tubing? Builders have climbed on the PEXCross- linked polyethylene. Specialized type of polyethylene plastic that is strengthened by chemical bonds formed in addition to the usual bonds in the polymerization process. PEX is used primarily as tubing for hot- and cold- water distribution and radiant- floor heating. Cross- linked polyethylene tubing is increasingly taking the place of copper in residential plumbing systems for a variety of reasons: ease of installation, resistance to acidic water, and the virtual elimination of leak- prone fittings. The Wirsbo Hand Expander tool comes in two models, a complete set with 1/2', 3/4', & 1' heads or just the tool itself. The heads can be purchased separately (they start with sku number Q631). The Wirsbo Expander Tool is one of. How Safe is PEX Tubing? Does this widely recommended type of plumbing contain hazardous materials? It all adds up to a juggernaut for a building material that's only been available in the U. S. An organic compound that evaporates readily into the atmosphere; as defined by the U. ![]() S. Environmental Protection Agency, VOCs are organic compounds that volatize and then become involved in photochemical smog production. The evidence either way seems slim This forum specializes in the sometimes arcane world of wall assemblies, thermal boundaries and moisture management, not plastics, suggests J Chesnut. Please select your region: You will only be asked this question once.The physician decided to take his chances with the copper supply lines instead of PEX, accepting the premium in cost. The experiment (purchase by end users) is only in its earliest stages. One can say the same about a long list of stuff, a lot of which is part of my daily life.. Copper is vulnerable to corrosion and pin hole leaks. Water turbulence in copper lines can increase the amount of dissolved lead and copper in the water, especially when the p. H is less than 6. When acidic or soft water sits in the line for more than six hours, the line should be flushed for up to 6. And in these conditions, hot water should never be used for cooking or drinking. PEX, on the other hand, is resistant to acids, better at resisting freezing damage, and doesn't scale or corrode. It's been used in Europe since the 1. Not- for- profit international standards organization that provides a forum for the development and publication of voluntary technical standards for materials, products, systems, and services. Originally the American Society for Testing and Materials. More troubling, the California lawsuit alleged PEX could indeed leach certain chemicals, including methyl tertiary- butyl ether (the MTBE referred to in the original post) along with ETBE, a related chemical, Riversong says. Or is this all overblown? Both PEX and copper are used in the homes of friends and family, writes Steve El, adding, . We filter our drinking water at the tap. Supposedly the filter is good for copper. That's good enough for us. The stuff we waste time worrying about is nuts. Whether PEX or copper is used seems somewhat mute if the main service is already carried in one of the worst types of pipe. The philosophic perspective used by our rule makers in defining 'safe' does not usually take this into account. No harm learning more about what's in stuff and how toxic it's thought to be though. And as others have made clear in this discussion, there is currently and to the best of our knowledge no clear winner. But a couple or so things to consider: There is a great Environmental Building News feature article entitled, “Piping in Perspective: Selecting Pipe for Plumbing in Buildings.” In it, many of the issues discussed in this blog, and more, are covered. And in subsequent EBN content on the topic of PEX piping it should be noted that bisphenol- A (BPA), while clearly an issue for plastics such as polycarbonate, is not clearly connected to safety concerns with PEX. So far, this is not an area of building materials that Pharos has addressed. But Pharos is becoming a bit more connected to GBA, at least indirectly, through the brand new partnership between Pharos and Building. Green’s Green. Spec. As a result of this GBA blog discussion, Green. Spec editors have rewritten the domestic water piping overview on GBA. It’s nothing conclusive unfortunately, but it does suggest that since there is no clear winner for piping, your selection is likely to be driven by project- specific design and construction considerations. For example, I prefer piping that best accommodates structured plumbing design and efficient hot water flow; the ability and ease with which PEX permits large radius bends reduces turbulence and means more efficient plug flow of hot water.
