On January 5, 2011, the 112th Congress of the United States amended the safe Drinking Water Act (SB-3874), adding the requirement that the federal definition of “lead free” in backflow preventers matches that of California and Vermont, being less than or equal to 0.25%. Essentially since the Bronze Age, lead has been added to bronze to make it a more usable alloy. The specific properties of lead allow for bronze to be more easily shaped and less brittle than without it. 20th Century backflow preventers often contained up to 8% lead, more than 30 times the new allowable limit. Nationwide, new laws are being passed requiring a lower percentage of lead present in backflow preventers. If you haven’t received a notice already, chances are you soon will, and you’ll be required to replace your equipment with a low-lead or no-lead solution. Keep in mind that not all backflow preventers are created equal. Whatever your replacement may be, ensure it is approved by The Foundation for Cross Connection Control & Hydraulic Research at the Engineering School of the University of Southern California, the internationally recognized authority in this area. Seeing this change coming “down the pipe,” A.R.I. has created 2 series of backflow preventers which use a nylon composite body. This innovative device is not only compliant with the new regulations, it goes beyond them by being 100% lead free! Further, as it doesn’t contain any of the brass or copper targeted by thieves, they have no reason to steal your investment.
