WSP Whole House UV Water Sterilizer - 10 GPM

Water that smells off or tastes strange can be a first sign of bacteria or other microorganisms in your well water. The WSP Whole House UV Water Sterilizer - 10 GPM uses ultraviolet light to help reduce these living contaminants across your entire home’s supply.

Noticing odd tastes or smells and stains that won’t scrub away?

When guests comment on water that tastes metallic or smells odd, or when you see stubborn staining in the sink or toilet, it’s more than a nuisance. These signs point to living microorganisms such as bacteria and viruses in your water. Unlike sediment or chlorine problems, these microbes can’t be filtered out by regular sediment or carbon filters. The presence of bacteria like E. coli or coliform can change how your water looks, smells, and tastes, and it’s a clear signal your water needs a different approach to treatment.

A control head that monitors and manages ultraviolet light

The heart of this system is the control head, which powers a UV-C lamp inside a stainless steel chamber. This lamp emits ultraviolet light at a wavelength that disrupts the DNA of bacteria, viruses, and cysts, preventing them from reproducing. The control head runs the lamp continuously and alerts you when it’s time to replace it. This ensures your water stays protected without guesswork, offering a reliable, no-chemical way to help reduce living contaminants.

Three-stage media to clear water before UV treatment

Before water reaches the UV chamber, it passes through a sediment filter and a carbon block filter. The sediment filter removes particles that would otherwise block the UV light, while the carbon media targets chlorine, taste, and odor. This pre-treatment is essential because UV light can only work effectively if the water is clear. Together, these filters prepare your water to be disinfected by the UV lamp.

A stainless steel reactor chamber designed for consistent, whole-house treatment

The water flows through a stainless steel UV reactor chamber sized to handle up to 10 gallons per minute. This means it can supply most average family homes with 3 to 4 people and 2 to 3 bathrooms. The exact size of the vessel will be confirmed when your system is sized for your water and home, ensuring it fits your needs.

Best suited for typical family homes with moderate water use

This sterilizer is intended for typical family households with water demands up to around 10 gallons per minute. If you have a larger home, more bathrooms, or higher peak water usage, you may want to consider a larger system. For smaller homes or lower flow rates, a smaller unit might be more appropriate. Confirming your home’s water flow helps ensure the system performs reliably without overtaxing the lamp or media.

What you receive and how to get started

The system includes the control head with the UV-C lamp and quartz sleeve, the stainless steel UV reactor chamber, and the sediment and carbon block filters. Water Softener Plus ships the system from Tampa with free U.S. delivery included in the price. Installation is by your own licensed plumber, and sizing help is provided to match your home’s water flow and quality. You can order online with confidence, backed by a 90-day money-back guarantee.

Who this size is right for

This is rated for roughly 10 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 bathrooms.

The number to match is peak simultaneous demand, not average use. Two showers and a dishwasher at once is the moment that finds an undersized unit, so size for that.
