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

If your well water shows signs of nitrate contamination—often from nearby farming activity—this nitrate reduction system is designed to help reduce those levels throughout your entire home. It uses a special resin that exchanges nitrate and nitrite out of your water and regenerates automatically, helping protect your family and your plumbing.

The problem you’re living with

If your water tastes metallic or has a slightly bitter edge, or you worry about fertilizer runoff from nearby farmland affecting your well, nitrate could be the cause. You might also notice that your water sometimes smells or tastes off when sulfate spikes occur, and you’ve likely read about the risks nitrates pose to infants and pregnant women. These contaminants don’t just affect taste—they can be a concern for your household’s long-term water quality. Simply put, nitrate in well water is a problem you can’t see, but you might sense in your water’s taste or your peace of mind.

Why it’s happening

Nitrate is a compound commonly found in fertilizers and septic system runoff. It can seep into well water when these sources are nearby. Unlike some contaminants you can filter out with a simple cartridge, nitrate is an ion—a charged particle—that requires a specific kind of water treatment. The way to confirm nitrate presence is with a laboratory water test focusing on nitrate and nitrite levels. That test is the one reliable check to know if your well has elevated nitrate that needs addressing.

What it’s costing you to leave it

Leaving nitrate untreated isn’t just about taste or smell. High nitrate can interfere with water use in ways you might not notice immediately—like causing your water to feel harsher or affecting how soaps and detergents work. Over time, you could spend more on cleaning and worry about the health risks nitrate carries for vulnerable family members. Fixing the problem reduces these ongoing costs and hassles, even if the water looks clear.

How this system fixes it

This system uses a nitrate-selective anion-exchange resin. In plain terms, the resin acts like a magnet for nitrate and nitrite particles in your water, swapping them out for harmless chloride ions from salt. When the resin gets full, it flushes itself automatically using a salt brine solution and then gets ready to work again. This cycle keeps your water’s nitrate levels reduced over the long run without needing cartridge replacements.

What this system can handle

The WSP Whole House Nitrate Reduction System can handle nitrate and nitrite in well water, even when sulfate levels fluctuate. It’s built for whole-house use, treating all the water coming into your home so every tap benefits. The system is sized to work for typical family water use, regenerating only when needed thanks to a metered control valve, which makes it more efficient than systems on a fixed schedule. This means you get consistent nitrate reduction without wasting water or salt.

What you actually get

When you order this system, you receive a fiberglass mineral tank filled with certified nitrate-selective anion-exchange resin, paired with a metered control valve that manages regeneration on demand. A bypass valve is included at no extra cost, allowing your plumber to isolate the system for servicing without cutting off water to your home. You also get 10 feet of discharge hose for the drain line. The pressure vessel itself carries a lifetime warranty, while the control valve and electronics come with the manufacturer’s standard warranty.

Is this the right size for you

This system fits most homes relying on well water with nitrate concerns of moderate levels, typical for many rural or semi-rural properties near farmland. If your household uses significantly more water or has very high nitrate levels, a larger or more specialized system might be necessary. Conversely, if your water nitrate levels are low or you only need point-of-use treatment, a smaller unit could be more cost-effective.

Living with it

Maintenance involves periodically adding salt to the brine tank and ensuring the system drains properly. Thanks to the metered valve, regeneration happens only when the resin needs it, which saves salt and water over time. Your licensed plumber can handle routine servicing, and the bypass valve helps keep water flowing during maintenance. Overall, it’s a low-effort system designed to work quietly in the background.

What it won’t do

This system is designed specifically for nitrate and nitrite reduction. It does not filter out bacteria, viruses, iron, manganese, hardness minerals, or organic contaminants. For those issues, you would need additional treatment systems tailored to those problems, such as UV sterilizers, iron filters, or water softeners.
