Product Questions & Answers

Have a UV question that hasn't been answered? Live chat with a RainDance specialist for a quick answer!

Q: How does the UV system remove bacteria?
A: As water flows past the UV lamp(s) in a UV disinfection system, microorganisms are exposed to Ultraviolet light energy. Ultraviolet light alters the DNA material in cells so that bacteria, viruses, molds, algae and other microorganisms can no longer reproduce. The microorganisms are considered dead, and the risk of disease from them is eliminated. The process of UV Disinfection is accomplished without adding any harmful chemicals to your drinking water and does not distort the water or effect its pH value.

Q: Will a UV system remove iron bacteria?
A: No, iron bacteria is a different variety of bacteria that will coat the entire UV system in a slimy substance, causing fouling and costly replacement. Iron bacteria is not necessarily a harmful bacteria, it is more of a nuisance and requires a chemical oxidation followed by filtration for effective removal

Q: Do I need a water softener with a UV system?
A: If your water hardness is over 7gpg (120mg/L) a water softener is recommended to prevent scale build-up on the quartz sleeve and reduce cleaning and replacement frequency.

Q: Do I need a sediment prefilter?
A: Sediment, debris, and turbidity can "shade" the UV lamp intensity which prevents effective disinfection and may cause bacteria to pass through the UV system. To ensure the most effective treatment, The Viqua IHS22-E4 includes (2) integrated prefilters First Stage: A 5 micron sediment & turbidity removal prefilter - Second Stage (1) A carbon filters to removes odors, chemicals, and off-colors

Q: Do I need a plumber to install?
 A: If you are handy and have basic plumbing skills you should have no problem with this installation. We provide detailed installation instructions, pictures, and offer several means of tech support for you or your plumber.
