Frequently Asked Questions: VIQUA UV Water Systems

Q: Do I really need a pre-filter before my VIQUA UV system?

A: Yes, absolutely. UV light requires a direct "line of sight" to destroy bacteria. If there are tiny physical particles of sediment, dirt, or debris in your water, pathogens can literally hide behind them and survive. Installing a 5-micron sediment pre-filter immediately before your UV unit is required to ensure complete disinfection.

Q: The UV bulb is still lighting up after 12 months. Do I still need to replace it?

A: Yes. While the bulb may continue to emit visible blue light for up to a couple of years, the specialized UV-C gas inside the lamp degrades and becomes too weak to kill bacteria after 9,000 hours (roughly 12 months) of continuous operation. Failing to change the bulb annually risks your water safety.

Q: How often do I need to clean or replace the quartz sleeve?

A: You should inspect and clean the glass quartz sleeve (the tube protecting the bulb) every 3 to 6 months to remove mineral scaling or cloudiness. The glass must be perfectly transparent to let the UV light pass through. We recommend replacing the quartz sleeve entirely every 24 months to avoid hairline fractures or permanent mineral clouding.

Q: Can I turn the UV system off when I am not using it to save power?

A: No. VIQUA systems are designed to stay running 24/7. Turning the unit off allows untreated water to flow past the chamber or permits bacteria to breed inside the chamber while the system is cool. Additionally, turning the controller on and off frequently will shorten the life of the lamp and the ballasts.

Q: What happens if my home experiences a power surge or a brief outage?

A: The digital controllers inside VIQUA systems contain sensitive electronic circuit boards. Fluctuations in electricity can easily damage or fry them. We strictly recommend plugging your system into a **high-quality surge suppressor** to shield your electronics from damage.

Q: Does a UV system fix hard water or remove bad tastes and smells?

A: No. A UV system is strictly a biological purification system designed to kill bacteria and viruses. It does not filter out heavy metals, odors, chemicals, or hard minerals. For taste and odor issues, you should pair the system with a carbon block filter. For hard water, a water softener must be installed *before* the UV unit to prevent mineral buildup on the sleeve.
