WSP Whole House Nitrate Reduction System - Well Water, Nitrite Removal

Just moved into a home with well water and noticed the water tastes odd or causes staining? That’s often due to nitrate from nearby farming leaching into your well. The WSP Whole House Nitrate Reduction System helps reduce nitrate and nitrite in your water, making it easier to use without the lingering effects that nitrate can cause.

Meeting your well water for the first time

When you start using your well water, you might see a persistent yellow or orange stain around your sinks or toilet tanks. Maybe the water tastes slightly metallic or different from what you expected. These signs come from nitrate and nitrite, chemicals commonly found in groundwater near agricultural areas where fertilizers or septic systems leak into the soil. They don’t change how your water looks clear, but they affect how it feels, tastes, and the upkeep your plumbing requires.

How the control head manages treatment and saves you effort

On top of the system is a metered control head that tracks the exact amount of water your home uses. It automatically starts a backwash cycle to rinse and refresh the treatment media, keeping performance steady over time. When necessary, it regenerates the resin inside by flushing it with salt brine. This cycle happens without you needing to intervene, ensuring the system stays effective while using only what it needs, helping you avoid wasting water or salt.

Media designed specifically to target nitrate and nitrite

Inside the tank, you’ll find a special mix of media tailored to your nitrate problem. The main part is a nitrate-selective anion-exchange resin that swaps nitrate and nitrite molecules out of your water and traps them in the resin. It’s designed to avoid releasing nitrate back into the water during changes in other minerals, unlike standard resin types. Supporting this is a layer of cation exchange resin that softens water by targeting hardness, and a graded gravel underbed that keeps water flowing evenly through the tank for consistent treatment.

The tank size and what it means for your home

This system comes in two tank sizes, roughly 10" by 54" or 12" by 52", filled with media volumes from 1.5 to 2 cubic feet. That means it’s built to handle flow rates around 10 to 15 gallons per minute. In practice, it can support large households comfortably, with five or more people and three to four bathrooms, without slowing down your water pressure or performance.

Who this system is built for

This nitrate reduction system suits a large home with substantial water use. It’s ideal if you have well water impacted by farming runoff or septic nearby, and if your household regularly demands water for several bathrooms and daily activities. If your home is smaller or has fewer occupants, a smaller system might fit better. Conversely, if you have an unusually high flow demand, consider a larger capacity to keep water moving smoothly.

What comes with the system and what to expect next

When you order, you get the complete nitrate reduction system ready for your local licensed plumber to install. It includes a bypass valve at no extra cost, letting you isolate the unit for servicing without shutting off water to your home. Ten feet of discharge hose is also included for the drain line setup. The tank itself carries a lifetime warranty on the pressure vessel, while the control valve and electronics have coverage per the manufacturer’s terms. We ship from Tampa with no added charge for U.S. delivery, and sizing help is ready whenever you need it. Ordering is straightforward — add the WSP Whole House Nitrate Reduction System to your cart to begin improving your water quality.

Who this size is right for

This is rated for roughly 15 gallons per minute of service flow, which suits a large home - around 5 or more people with 3-4 bathrooms.

Check this against your peak demand rather than your daily total. A unit that is marginal on flow will drop pressure at exactly the times you notice it most.
