VIQUA is proud to be one of the world’s leading suppliers of residential and light commercial UV water treatment systems, providing treated water without the use of chemicals. Available as point-of-entry or point-of-use solutions, VIQUA UV systems inactivate common waterborne pathogens*— including cryptosporidium, giardia, pathogenic E. coli (STEC/VTEC), campylobacter, legionella, salmonella, shigella, norovirus, enterovirus, and hepatitis A virus—to deliver on our promise continuously: consistently better water.†   

*Efficacy of VIQUA UV systems has been demonstrated in internal testing using surrogate organisms, specifically MS2 Phage. MS2 is a well-documented surrogate organism that is accepted in the water treatment industry in the design and testing of UV systems being used to treat cryptosporidium and giardia. Contact VIQUA for the details on internal testing performed.   

† Versus identical incoming water that is not treated with a UV system. Based on internal efficacy testing, VIQUA UV treatment systems, when installed in accordance with the manufacturer’s recommendations and with use of a VIQUA UV lamp that is within its expected life, and subject to mechanical and water quality variables, can inactivate common waterborne pathogens. Actual efficacy of any particular VIQUA UV system will be dependent upon mechanical and water quality variables, including incoming water quality, the specific pathogen(s) present, the age of the UV light bulb, etc. Accordingly, no guarantee can be provided of the actual percentage of common waterborne pathogens inactivated in an application.

Start by selecting your UV water treatment model above. You'll be taken to a page that provides manuals or instructions for your specific model. Using a UV light system can protect your home or business from harmful bacteria, viruses, and other pathogens. However, the effectiveness of your UV water disinfection system requires timely replacement of the UV lamp and proper cleaning of the sleeve. Neglecting these steps could expose you to potentially harmful microorganisms in the water. General UV bulb replacement instructions are available.

To ensure optimal performance from your Viqua UV water treatment system, regular cleaning and maintenance are important. Over time, mineral deposits can accumulate on the UV sleeve, which can diminish the UV light's effectiveness. To clean your UV quartz sleeve, turn off the system and carefully remove the UV lamp. Then, using a soft cloth and a mild cleaning solution, gently wipe the quartz sleeve to remove any deposits or build-up. Dry the sleeve completely before reassembling. In addition, the UV lamp itself has a specific lifespan, often about a year, and should be replaced per model specifications. Always consult the system's user manual for specific cleaning instructions and maintenance schedules to ensure the UV disinfection system operates efficiently and safely.

For optimal performance and to ensure continuous disinfection, it's recommended to replace the UV lamp in your Viqua system annually, although some Viqua lamps are designed to work longer. Pay attention to the recommended lamp repalcement schedule as over time, the intensity of the UV light decreases. Regularly changing the UV bulb ensures that the water passing through the system receives effective UV exposure, safeguarding against harmful microorganisms and maintaining the system's disinfection efficacy. It is also important to purchase and install genuine Viqua lamps.

Viqua lamps are specifically designed and tested to deliver the precise UV dosage required to effectively neutralize harmful microbes in the water. Off-brand or generic lamps may not offer consistent ultraviolet output or might degrade more rapidly, compromising the water treatment process. Additionally, using off-brand lamps can void the system's warranty, leading to potential costs in the event of system malfunctions. Genuine Viqua lamps also ensure that you are getting a product that meets the highest quality and safety standards, offering peace of mind that your water remains safe.
