help PureStream Sentinel FAQ

Does the PureStream Sentinel remove heavy metals or chlorine from the water?

No, the PureStream Sentinel is specifically designed for disinfection and lacks the physical filtration media required to remove chemicals like chlorine or heavy metals. It strictly uses Ultraviolet light to neutralize biological contaminants like bacteria and viruses.

How often do I need to replace the UV lamp in the PureStream Sentinel?

The Ultraviolet lamp in the PureStream Sentinel system typically needs to be replaced once every 12 months, even if the light is still glowing. Over time, the bulb's ability to emit the necessary UV-C spectrum degrades, compromising its ability to disinfect the water.

Can the PureStream Sentinel handle a whole-house water flow rate?

Yes, whole-house UV disinfection systems like the Sentinel are sized to handle the standard flow rate of a residential home, which is usually between 8 and 15 gallons per minute. This ensures that all water entering the house is exposed to adequate UV light for sterilization.

What happens to the bacteria when they pass through the UV chamber?

The intense UV-C light emitted by the system penetrates the cell walls of the bacteria and severely damages their DNA. This prevents the microorganisms from replicating, effectively rendering them harmless and ensuring your water is safe to consume after a pipe breach.
