Including filter system and high-performance Lead filter.
Lead in household water most often comes from plumbing materials rather than the municipal source. When water sits in older pipes, solder, or certain brass fixtures it can leach tiny amounts of lead into the taps you use every day. Because lead has no reliable taste or smell, it can be present even when water looks and smells normal, and many Marathon homeowners first find out through a test, inspection, or utility notice. Coastal salt air and storm exposure here can speed corrosion, so properties in the Keys should be especially mindful of plumbing-related risks.
Lead levels in a home can be inconsistent — varying by faucet, time of day, and how long water has been sitting in the lines — which is why it can feel unpredictable for Marathon families. Hot water can dissolve more lead than cold, affecting showers and cooking. While replacing fixtures and piping is ideal, it’s often impractical to find and remove every lead source at once, especially in older properties or those with wells or cisterns. A whole-home treatment that reduces lead at the point of entry gives homeowners confidence while longer-term plumbing repairs are planned.
For whole-house lead reduction in a Marathon residence, a backwashing carbon tank blended with KDF media is one of the most effective single-tank solutions. Activated carbon is excellent for chlorine and odor control, while KDF works via a redox process to target heavy metals like lead as water moves through the media. The backwashing feature periodically flushes out trapped particles so the media bed stays cleaner and performance remains consistent — a useful trait in coastal homes where sediment and corrosion can be concerns. Installed at the main water line, this setup treats water to every tap so you’re not relying on a single sink filter.
A whole-house backwashing carbon + KDF system is sized to your home’s flow so showers, laundry, and outdoor use around Marathon — from Key Colony Beach to Grassy Key — keep normal pressure while water is treated. It also captures fine sediment that can carry lead particles and eases other water quality stresses that accelerate pipe corrosion in humid, maritime climates. Because lead exposure is often tied to what water contacts on its way to the faucet, treating incoming water reduces risk across all daily uses; Mr. Pure Water can assess your plumbing, moderate water hardness, and property needs to recommend the right configuration.
