Pentek Bacteria & Coliform (Well) System
Head valve + tank + media, matched to solve bacteria & coliform (well) — sized and shipped free.
When your well water carries bacteria and coliform contaminants, it’s more than just an unpleasant nuisance—it’s a serious threat to your family’s health and your home’s plumbing. Cloudy or foul-smelling water, unexpected skin irritations, and persistent pipe corrosion aren’t just signs of a problem; they’re warnings that harmful microbes are thriving in your water supply. Ignoring these symptoms can lead to costly repairs, frequent illness, and a compromised household environment.
The system that fixes it
The Pentek Bacteria & Coliform (Well) System is engineered to tackle these specific threats at their source, delivering complete protection for your well water. At its core lies the reliable Pentek-series backwashing control valve — a precision-engineered head valve that automatically manages the system’s cleaning cycles. This valve ensures media longevity and consistent performance by flushing out trapped contaminants without manual intervention. Unlike generic valves prone to early failure or complicated repairs, the Pentek-series valve is a genuine, serviceable component designed for easy maintenance and durability, meaning you can count on long-term reliability.
The system is built on a robust whole-house contact and filtration tank customized for your water volume, ensuring every drop is treated before entering your home. Inside, the specially formulated media blend combines KDF-55 with catalytic carbon, uniquely bacteriostatic to suppress bacterial growth while stripping chlorine and odors from your water. When paired with our well water UV stage (available in the bundle), you receive a full-spectrum disinfection approach that protects not only your health but your entire household plumbing system.

How the media works
The heart of this filtration system lies in its specialized media: a blend of KDF-55 and catalytic carbon. KDF-55 is a proven material that uses a chemical process to inhibit bacteria growth, thereby creating a bacteriostatic environment that reduces microbial contamination. Alongside this, catalytic carbon traps and neutralizes chlorine and foul odors without adding chemicals. Together, these media work in tandem to actively suppress bacteria and coliform in your well water, helping to prevent their proliferation while improving taste and smell. This media combination sets a foundation for healthier water even before the UV stage finalizes disinfection.
