Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide-ranging group of microorganisms that can show up in household water and inside plumbing fixtures. You may also see the term heterotrophic plate count used — it’s a lab method that estimates overall bacterial growth rather than identifying a single pathogen. In Craggs homes, homeowners typically spot signs like musty smells, slimy film on showerheads or faucet aerators, or faster biofilm buildup when these general bacteria are present.
Levels of heterotrophic plate count can increase when water sits idle in pipes, when sediment or organic matter is available for bacteria to feed on, or when plumbing allows biofilms to form. These conditions can also bring subtle changes in taste or odor. While many heterotrophic bacteria aren’t known to cause disease, higher HPC bacteria readings often indicate your home’s water system needs attention. A whole-house solution can treat the water as it enters your Craggs residence and reduce the factors that let regrowth occur downstream.
For controlling HPC bacteria throughout a house, a whole-house ultraviolet (UV) disinfection system is generally the most effective single filter-style option. UV works by inactivating microorganisms as water flows through a stainless chamber exposed to a UV lamp, treating water in real time without adding chemicals or altering taste. When installed where water enters a Craggs home, a properly sized UV unit protects every tap, shower and appliance.
UV systems need relatively clear water so the light can reach microbes; heavy sediment, iron or cloudiness can shield organisms and reduce effectiveness. That’s why many whole-house UV installations include prefiltration, while the UV stage remains the core technology targeting HPC bacteria. Correct sizing for your household flow and scheduled lamp and sleeve maintenance keep the system performing; Mr. Pure Water can help Craggs homeowners select and install the right whole-house UV setup for reliable control of heterotrophic plate count.
