Including filter system and high-performance Shigella filter.
Shigella is a bacterial contaminant that can enter water supplies through human waste when cross-connections, backflow, or distribution system problems occur. Because only a small exposure can cause illness, homeowners in Avalon take any notice about Shigella seriously. Even if your water is treated by a utility, contamination can happen after the plant and before the faucet, so many local families choose a whole-house approach to maintain consistent protection throughout the home.
Worries about Shigella in household water often arise after boil-water advisories, plumbing incidents, or wider contamination alerts. Bacterial issues aren’t detectable by taste or smell, so you can’t rely on senses to know if water is safe. That uncertainty leads many Avalon homeowners to put a plan in place at the point where water enters the house, and addressing microbial risks at the whole-house level is a practical way to add peace of mind.
The single most effective whole-house option for controlling Shigella is a UV water disinfection system. UV inactivates microorganisms by exposing them to ultraviolet light at the right intensity so bacteria cannot reproduce. It’s chemical-free and treats all incoming water rather than just one faucet, and when the unit is sized correctly for your home’s flow rate it provides robust protection against bacteria like Shigella.
UV systems perform best when water is clear enough for the light to penetrate, so they’re often installed with a prefilter to remove sediment and cloudiness that could shield microbes. The UV chamber on your main line is the component that controls Shigella, and reliable performance depends on proper sizing, an uninterrupted power supply, and periodic lamp replacement. Mr. Pure Water can assess Avalon homes and recommend the right whole-house UV setup for your plumbing and water conditions.
