Chloramine can accelerate the leaching of lead from lead pipes, soldering, and even brass plumbing components labeled as "lead-free." This leaching can contribute to lead poisoning, presenting serious health risks such as neurological damage, particularly in young children, where it can affect brain development and cause behavioral issues.

Chloramine can cause pinhole pitting in copper pipes, a form of corrosion that results in small leaks. These leaks not only increase the risk of water damage but can also lead to mold growth within homes. Certain molds can be highly toxic and cause a range of health problems, including respiratory issues and allergic reactions.

Your state environmental protection agency or health department may also have more information about PFAS in your drinking water and recommendations for actions you can take.

Plumbing parts made of rubber, such as toilet flappers and shower gaskets, can deteriorate more rapidly due to chloramine exposure. The corrosion of these components necessitates their replacement with chloramine-resistant materials, such as specific synthetic polymers, to prevent frequent failures and leaks.

The implications of chloramine use in residential plumbing are significant, encompassing not just the substantial repair and replacement costs for homeowners but also potential health risks associated with lead exposure and toxic mold infestations. Awareness and proactive measures, such as regular plumbing maintenance and using chloramine-resistant materials, are essential to mitigate these risks.
