Including filter system and high-performance Lead filter.
Lead in household water usually comes from plumbing rather than the municipal source. When water sits in contact with older pipes, solder, or certain brass fixtures it can leach small amounts of lead into the water you use every day. Because lead has no reliable taste or smell, it can be present even when your water seems fine — many Cox homeowners only discover it through testing, a utility notice, or a home inspection.
Low or fluctuating lead readings are common and can change by faucet, time of day, or how long water has been sitting in the lines. Hot water often picks up more lead than cold, which is important for bathing and cooking in Cox homes. While replacing lead-containing plumbing parts is ideal, finding and swapping every component isn’t always practical. A whole-house treatment that reduces lead at the point water enters the home offers consistent protection while you address potential sources.
A single-tank backwashing carbon filter combined with KDF media is one of the most effective whole-house options for reducing lead in residential systems. Activated carbon is excellent for chlorine and taste/odor issues, while KDF media uses a redox process that helps reduce dissolved lead as water flows through the tank. The backwashing function periodically flushes trapped particles and refreshes the media bed for steadier performance over time. Installed at the main water line, this setup treats every tap in your Cox home so you’re not relying on a single sink filter.
Systems like this are sized to your home’s flow rate so showers, laundry, and outdoor use run without significant pressure loss. They also capture fine sediment that can carry lead particles and help reduce other water issues that stress plumbing. Because lead risk often depends on what water contacts on its way to the faucet, treating water as it enters the house limits exposure across everyday uses. Mr. Pure Water can assess your Cox plumbing and water conditions to recommend the right configuration for whole-home protection.
