Protection from Waterborne Cysts, Bacteria and Viruses
The RainSoft RCUV Series incorporates the time-tested technology of ultraviolet light to reduce some of the most common microorganisms found in water.

How Does the RCUV Work?
NSTALLATION
The RCUV ultraviolet water disinfection unit installs in your home’s main water line.
UV DISINFECTION
Water passes through the UV chamber, where many bacteria and viruses are killed or rendered harmless by direct exposure to the UV light.
COST EFFECTIVE
A short few seconds exposure to UV light, requiring less energy than a typical household light bulb.
LOW MAINTENANCE
Annually changing the UV lamp, a service that your RainSoft dealer will perform for you, is the only servicing required.
LOW MAINTENANCE
Visual and audible alarms let you know in advance when the UV lamp is in need of replacement.
Understanding UV Water Disinfection
In RainSoft RCUV Series water disinfection systems, an ultraviolet lamp is centered within a protective quartz sleeve in the unit’s precisely engineered and polished stainless steel disinfection chamber. This ensures even distribution of UV energy to all water passing through the unit. Microorganisms are bombarded with a lethal dose of UV light, destroying bacteria and inactivating many viruses.
Ultraviolet disinfection provides many of the same benefits as distillation without removing beneficial minerals from the water. UV disinfects water using high intensity light energy. Unlike chemicals, it does not leave unwanted residuals or by-products in the water. Since there are no chemicals, UV does not affect the taste, odor or clarity of the water. For this reason, UV is often combined with other water treatment devices such as carbon filters, water conditioners and reverse osmosis to provide complete water quality solutions. Incoming water to the ultraviolet disinfection system should be filtered to a minimum of 5 microns. Your authorized RainSoft distributor can assist you in making this determination.
Do not use the RainSoft RCUV Series with water that is microbiologically unsafe or of unknown origin. For such applications, the RainSoft RCUV-NSF Series is required. These systems are not intended to convert wastewater or raw sewage to drinking water. The system is intended to be installed on visually clear water. Your local RainSoft dealer can assist you in making these determinations.

Our Testimonials
We live a considerable distance away from the city where Rain Soft is located but have never had any problems with the system itself. We were proud to recommend it to our son when he brought the place from us. He has no problems as of this date. Thank you for your service!
Rainsoft is a great product that comes with great service. We feel it was an investment, but we feel it was worth it. We have the Ultrefiner Drinking Water System that we use for all of of water bottles on the go - they stay clean - no yellow or pink film…. The Water Conditioning System is efficient and we used about 6 bags of salt in the last year - active family of 2 with family stopping in. Would highly recommend Rainsoft.
We have been with Rain soft since 1999. We recently purchased a new softener and decided to stay with Rain soft because of their excellent service and quality of product. We have had the reverse osmosis system since the beginning and have also added the chlorine removal tank. We enjoy having the quality water that our system provides us with. Thanks to rain soft. Brent and Carla Whitlock.
Will make this short. Had some problem with our water softener. Had water on the floor. It would make all kinds of noise and the our water softness was inconsistent. Lucas came and took the time to fix it right! Our water softener has never worked this well. Be sure to let Lucas know much we appreciated his work!!
RainSoft has delivered excellent service and products since we installed a whole house water system more than 20 years ago. We recently replaced our refrigerator and RainSoft came the next day to connect the new water line for our ice/water. Prompt and friendly service!
Blake was awesome and the warranty on the products is very good. Blake took the time to replace all potential problem parts in the system at no additional charge. Living in the country with well water is hard on the system but I don’t know what I would do without it. Blake also had some extra bags of salt on hand to save us a trip. Very professional and obviously took pride in doing things right!
