Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a group of microbes used to gauge how sanitary water is. If testing finds coliform bacteria in your supply, it can mean untreated water is entering through a damaged well, a plumbing cross-connection, or other intrusion. Often there’s no change in taste or smell, so lab testing is the reliable way to know. You may also see the phrase total coliforms on reports, which refers to that broader coliform group.
In Fincher homes, a common response to a total coliform detection is to confirm the result with repeat sampling, address likely points of entry, and add a whole-house barrier to protect every tap. Total coliforms aren’t the same as E. coli, but their presence can indicate conditions where other microorganisms might be present. Because test results can change over time, many homeowners prefer treatment at the point where water enters the house to ensure consistent coverage.
For treating coliform bacteria in the home, the most effective single whole-house option is typically a UV disinfection system installed at the point of entry. UV systems use ultraviolet light to inactivate microorganisms as water flows through the chamber, treating the entire household without adding chemicals. This method targets microbes directly rather than relying on taste-or-odor media, and when sized for your home’s flow it can protect every faucet in the house.
UV works best when feed water is relatively clear because heavy sediment can shield microbes from the light; for that reason Fincher homeowners often pair a prefilter ahead of the UV unit. If you’re selecting a single primary technology specifically for total coliforms, UV is the proven workhorse. Mr. Pure Water can help pick the right UV model for your plumbing and peak demand and provide proper installation plus routine lamp and sleeve service to keep treatment reliable.
