Including filter system and high-performance E. coli filter.
Finding E. coli in household water is a warning that bacteria may be entering your supply somewhere along the system servicing Franjo homes. Causes commonly include breaches in distribution lines, plumbing cross-connections, or vulnerabilities in private wells that allow human or animal waste into the plumbing. Water can look clear and still contain microbes, and many Franjo homeowners only discover a problem after a lab test, a public advisory, or repeated worries about water quality.
You may also see the name E. coli O157, a strain noted for causing more serious illness; whether it’s general E. coli or E. coli O157, the aim inside your Franjo home is the same: keep harmful bacteria out of the water you drink, cook with, and bathe in. Short-term measures such as boiling can make water safe at a single faucet, but they won’t shield every tap. A whole-house strategy ensures treated water flows consistently to the kitchen, bathrooms, laundry, and showers throughout the house.
For dependable control where water enters a Franjo residence, the most effective single-filter choice is a whole-house ultraviolet (UV) disinfection system. Installed at the point of entry, a UV unit uses ultraviolet light to inactivate microorganisms as water passes through the chamber. Because it works continuously and without chemicals, UV can protect every tap at once—making it a strong solution when bacterial contamination is the primary concern rather than taste or mineral scale.
UV disinfection performs best when the incoming water is clear enough for light to penetrate, so it’s commonly paired with a sediment prefilter to remove cloudiness that can hide microbes. Sized correctly for your Franjo home’s flow rate and maintained with regular lamp and sleeve servicing, a UV system offers ongoing protection against E. coli and other waterborne bacteria without leaving a disinfectant taste. For homeowners focused on reducing bacterial risk throughout the house, UV is typically the first technology to consider.
