What Is a UV System & How Does It Work?
A UV (ultraviolet) disinfection system exposes flowing water to a calibrated UV-C light inside a stainless chamber. The UV energy inactivates microorganisms like bacteria, viruses, and protozoa so they cannot reproduce or cause illness. Unlike chlorine, a UV filtration system for well water adds no chemicals, taste, or odor—and there’s no risk of overdosing.
- Core components: UV lamp (bulb), quartz sleeve, stainless chamber, power/controller.
- What it does: Disinfects microbiological contaminants; final barrier for potable water.
- What it doesn’t do: It does not remove sediments, hardness, or chemicals—pair with filters/softeners as needed.
Why Choose VIQUA (Sterilight Heritage)
VIQUA—known for integrating the legacy of Sterilight UV—is widely trusted for residential and light commercial UV. Their controllers are intuitive, parts are readily available, and models scale from small cabins to large multi-bath homes. If you’re searching viqua sterilight uv systems or viqua uv sterilizer, you’re in the right place.

Remember to budget for annual lamp replacements and occasional sleeve cleaning/replacement.
VIQUA Replacement Parts
Keep performance high with genuine VIQUA replacement parts:
- Lamp (Bulb): Replace annually (≈9,000 hours) for consistent dose.
- Quartz Sleeve: Clean during each lamp change; replace if etched or cloudy.
- O-Rings & Seals: Inspect and replace to prevent leaks.
- Controller/Power Supply: Rare but available if damaged or faulty.
How to Install a VIQUA UV Light (Overview)
Many homeowners install UV as a final, point-of-entry stage after sediment, carbon, and (if needed) a softener. The basic flow is: well/city water → sediment filter → carbon filter → softener (if used) → VIQUA UV system → home plumbing.
- Pick the location: Dry, accessible, near an outlet. Leave room to remove the sleeve/lamp.
- Mount the chamber: Follow arrow for flow direction; secure vertically or horizontally per manual.
- Plumb in/out: Use unions/shut-offs and a bypass. Avoid sweating pipes next to installed O-rings.
- Install the quartz sleeve: Handle with clean hands; don’t overtighten end nuts.
- Insert the lamp: Slide carefully into the sleeve; connect to the controller.
- Power & leak test: Restore water slowly; purge air; check for drips at fittings/O-rings.
- Final placement: Ensure UV is last in line; confirm pretreatment filters are fresh.
Always follow the specific model manual for torque, O-ring lubrication, and electrical safety.
How to Reset a VIQUA UV Light Alarm
After changing the lamp, the controller may keep an alarm or countdown until you reset it. On most VIQUA controllers:
- With power on, press and hold the reset or “lamp counter” button (model-dependent) for several seconds.
- Wait for the beep/display prompt indicating a successful reset.
- If the alarm persists, double-check the lamp connection and the model-specific reset sequence.
Exact steps vary—see your controller label/manual for the correct button and hold-time.
Maintenance & Best Practices
- Annual Lamp Replacement: UV lamps dim with age even if they still light—replace every ~12 months.
- Quartz Sleeve Care: Clean each year; mineral film reduces UV dose.
- Pretreatment: Keep sediment/carbon filters fresh to protect sleeve clarity and maintain flow.
- Power Protection: Use a surge protector or UPS to protect the controller.
- Vacation Mode: If leaving for long periods, follow manual guidance for safe power down/up.
UV Filtration System for Well Water
For private wells, UV is the final barrier. Proper pretreatment is essential: sediment (5–10 micron), carbon (for taste/odor), and softening if hardness or iron/manganese are present. This ensures clear water so your UV chamber can deliver the right dose.
- Clarity first: Turbidity/cloudiness blocks UV light—keep filters fresh.
- Iron/Manganese: Address upstream (softener or dedicated media) to prevent sleeve fouling.
- Flow sizing: Choose VH410-class if you have simultaneous showers, laundry, and kitchen use.

FAQ: VIQUA UV Water Systems (2026)
What is a UV system and how does it work?
A UV system passes water by a UV-C lamp inside a quartz sleeve. The energy inactivates microbes so they can’t reproduce. No chemicals, tastes, or odors are added.
VIQUA VH200 vs VH410 — which should I choose?
VH200 is great for small–mid homes with moderate peak flow. VH410 handles higher simultaneous demand (multi-bath homes). When in doubt, size up.
What are VIQUA UV systems cost ranges?
Compact residential units fall in the value–mid range; higher-flow residential systems are mid–premium; light commercial is premium. Budget for annual lamp replacements.
How often do I replace VIQUA UV light bulbs?
Every ~12 months (≈9,000 hours). Lamps dim with age even if they still light—replace annually for full UV dose.
How to replace a VIQUA UV light and clean the sleeve?
Shut water/power, depressurize, remove end nut, gently pull lamp, clean sleeve with non-abrasive cleaner, reinstall with fresh O-rings if needed, then reset the controller.
