Including filter system and high-performance Fecal Coliform filter.
Finding fecal coliform in household water is a warning that contamination pathways may exist. These bacteria serve as indicator organisms, so their detection can signal sanitary problems and the potential for other microbes to enter the supply. Sometimes you’ll notice cloudiness, sediment, or an unusual smell, but often fecal coliforms are present without visible signs. In Franjo, private well users should be aware that runoff after heavy rain, flooding, or damage to a well cap or casing can allow bacteria into the system.
Problems can occur even with treated municipal water when pressure changes, disturbed lines, or backflow let contaminants in. Because fecal coliforms indicate contamination risk rather than only causing taste or odor issues, start with proper water testing and select treatment based on those results. Many Franjo homeowners look for solutions after a lab report, a boil-water advisory, or persistent worries about water safety — a clear testing-and-treatment plan reduces guesswork and unnecessary add-ons.
For whole-house protection where water enters your home, the most effective single-filter solution for fecal coliform is a whole-house ultraviolet (UV) disinfection system. Rather than removing particles, UV uses concentrated ultraviolet light inside a stainless-steel chamber to inactivate microorganisms as water passes through. Properly sized and installed, UV is commonly used to control bacteria without adding chemicals or altering taste, giving Franjo families continuous, automated disinfection at every tap.
UV systems work best when the incoming water is clear enough for the light to penetrate, so they’re often paired with a prefilter to cut turbidity, rust, and silt that might shield microbes. The UV unit remains the primary disinfection step targeting fecal coliforms as water is distributed through the house. Mr. Pure Water can help Franjo residents confirm the correct flow rate, placement, and maintenance plan so the system continues to perform for showers, laundry, and kitchen use.
