Dezincification has been an ongoing topic of conversation when discussing open loop copper plumbing systems. A prevailing misconception is that bronze valves are the only reliable option for dezincification resistance. However, due to changes in lead-free requirements as a result of the Safe Drinking Water Act, additional options have presented themselves as new, viable alternatives to bronze. Heat treated, dezincification resistant brass valves are becoming a popular specified product within the engineering community. When subjected to International Organization for Standardization (ISO) 6509 testing, it is proven that heat treated dezincification resistant brass valves will perform as well as bronze in fighting against corrosion.
