VIQUA Whole Home UV Water System

What this system actually does — and what it does not

Two sizes: Choose the 9 GPM VH200 (CP-WHS-UV-9, $685) or the 18 GPM VH410 (CP-WHS-UV-18, $880) for larger homes. These are standalone system prices. The lamp specifications and replacement parts below describe the VH200; use the correct parts for your selected model.

The exact supplied model suffix is awaiting Sentry confirmation. Cory names “200H and 410” and links both standard VH-series and -V Class B sheets. Those documents do not establish which variant ships with each Sentry SKU.

Model and certification scope

Catalog labels identify VH200 at 9 GPM and VH410 at 18 GPM. These match VIQUA standard-dose flow labels, not the Class B certified flows. We do not claim a particular NSF/ANSI 55 class or microorganism efficacy for the supplied unit until the exact variant and its certificate coverage are confirmed.

See the standard-series specification and the VH200-V / VH410-V / VH410M-V specification. A qualified installer must match the actual model to source-water conditions and required treatment flow.

Maintenance: what it takes to keep this system effective

Annual lamp replacement — this is not optional

UV output from any lamp degrades over time. After roughly a year of continuous operation, the lamp’s output weakens enough that it may no longer deliver a reliable disinfection dose — even though the lamp itself is still glowing. A visually lit lamp is not a working lamp. Replace it on schedule regardless of appearance.

The process is straightforward: power down, swap the lamp, restart. The controller (BA-ICE-CL) monitors the system and will alert you when service is due.

Sleeve cleaning — as needed

The quartz sleeve surrounding the lamp must stay clear for UV light to pass through into the water. Mineral scale and biofilm can accumulate on the sleeve over time and reduce UV transmission. Wipe it clean during each lamp change at minimum; inspect more frequently if your water has high hardness.

Pre-filtration — the non-obvious maintenance lever

Turbid or sediment-laden water is the enemy of UV effectiveness. Any particulate that can shield a pathogen from direct UV exposure undermines the system. If you are on well water or surface-influenced supply, run a sediment pre-filter upstream of the VH200. Keep that pre-filter on its own replacement schedule.

Installation: professional is the right call here

The VH200 installs at the point of entry — meaning it treats all water entering the home before it branches to any fixture. That location is ideal for whole-home protection, and it is also where your home’s main plumbing and electrical supply converge.

Professional installation is recommended. This system requires both plumbing connections (fitting the unit into your main supply line) and a dedicated electrical connection for the 35W lamp and controller. An improperly plumbed point-of-entry install can affect water pressure throughout the house. Get it done right once.

Who this system is for

The VH200 is the right tool if any of the following describes your situation:

• Private well water — wells have no municipal disinfection backstop; bacteria and cysts from surface runoff, agricultural activity, or septic proximity are real risks
• Surface-influenced water — water sources that respond to rainfall or runoff events can carry transient microbial contamination
• Post-filtration microbiological layer — you already have whole-house or well filtration handling chemicals and sediment, and you want a dedicated UV treatment stage on top of it (per VIQUA’s own claims for the model supplied)
• Immunocompromised household members — cryptosporidium and giardia are disproportionately dangerous for people with weakened immune systems; UV addresses both without chemical additives
• Boil-water advisory history — if your area has a track record of advisories, a UV system is exactly what those advisories are trying to substitute for

The filter-first rule

If you are pairing the VH200 with a whole-house filtration system, install filtration upstream of the UV unit. Filters remove the turbidity and particulate that would otherwise shade pathogens from the UV lamp. UV then handles what filters cannot: the living microorganisms that pass straight through mechanical and chemical filtration media.
