Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a collection of microbes commonly used to gauge water sanitation. If a Littman water test comes back positive for coliform bacteria, it often means untreated water may be entering the system through a damaged well, a cross-connection, or a plumbing intrusion. Because these organisms usually don’t change taste or smell, homeowners rely on lab results to spot them. You may also see the phrase total coliforms on your report, which refers to the broader group of coliform organisms.
When total coliforms appear in Florida testing, the usual response is to confirm the finding with repeat samples, fix any likely entry points, and consider a whole-house barrier to protect the home. Total coliforms aren’t the same as E. coli, but their presence can indicate conditions where other microbes might exist. Because levels can fluctuate, many Littman homeowners choose treatment at the point where water enters the house so every faucet receives protection.
For coliform bacteria, the single most effective whole-house option is typically a UV disinfection system installed at the point of entry. UV systems expose flowing water to ultraviolet light that inactivates microorganisms throughout the home without adding chemicals. This method directly targets microbes rather than relying on taste-and-odor media, and when the unit is sized for your household flow it provides consistent, whole-home coverage.
UV works best when incoming water is relatively clear, since heavy sediment can shield bacteria from the light; that’s why many Littman homes pair UV with a prefilter. If you’re selecting a single primary technology for total coliforms, UV is the dependable choice. Mr. Pure Water can help size and install the right UV unit for your plumbing and peak demand, and with routine lamp and sleeve maintenance it delivers reliable whole-house protection against coliform bacteria.
