Viqua VH200 UV System

Whole-Home UV Water Disinfection System

The Viqua Sterilight VH200 UV System is a compact, high-performance ultraviolet (UV) water disinfection system designed for residential and light-commercial point-of-entry applications. Engineered to inactivate harmful microorganisms without the use of chemicals, the VH200 uses a high-output UV-C lamp to help protect your household’s drinking water from bacteria, viruses, protozoan cysts (such as Cryptosporidium and Giardia), E. coli, and fecal coliforms.

Overview

The Viqua VH200 is ideal for whole-house water treatment in homes, cottages, and light commercial settings where safe, chemical-free disinfection is required. Its space-efficient chamber and high-output lamp technology provide the same germicidal performance as larger systems while keeping installation footprint minimal. Built with user convenience in mind, the VH200 includes a digital countdown lamp life display, audible alarms for lamp failure and replacement reminders, and constant current operation to ensure stable UV output despite power fluctuations.

Key Features & Benefits

• Powerful UV-C disinfection: Helps inactivate bacteria, viruses, and protozoa without chemicals or additives.
• Compact, space-efficient design: High-output UV lamp technology and a streamlined chamber make it suitable for tight installations.
• Digital lamp life countdown + audible alarm: Alerts you when it’s time to replace the UV lamp — reduces guesswork and ensures continued protection.
• Constant current ballast: Maintains stable UV intensity even with minor power fluctuations.
• Reliable and easy maintenance: Long-lasting UV lamp (~9,000 hours or ~1 year), simple annual service routine, and straightforward installation.
• Durable construction: Stainless steel chamber resists corrosion and withstands standard plumbing conditions.
• Flexible connection: ¾″ to 1″ MNPT combo inlet/outlet for broad plumbing compatibility.

Compatibility

The VH200 integrates seamlessly into most cold potable water systems and can be paired with pre-filtration (recommended) to protect the UV chamber from particulates. It’s suitable for:

• Whole-home point-of-entry UV disinfection setups
• Cottages, cabins, and residential systems
• Applications requiring chemical-free microbial control
• Standard ¾″–1″ MNPT residential plumbing

Replacement parts: Compatible with Viqua S200RL-HO UV lamps and quartz sleeve QS-001 for maintenance.

Maintenance

• Replace the UV lamp annually (≈9,000 hours) or when the countdown display indicates service is due.
• Inspect and clean or replace the quartz sleeve if mineral scale or deposits accumulate — keeping UV transmission high.
• Check O-rings and seals during service to maintain a leak-free system.
• Ensure pre-filter cartridges (if installed) are replaced as recommended to reduce suspended solids before UV treatment.

The VH200 balances reliable water disinfection with compact design and easy serviceability — making it a strong choice for homeowners who want chemical-free protection from microbial contaminants without sacrificing performance or convenience.
