WSP 6 GPM Whole House Nitrate Reduction System

If your well water has nitrate levels raised by nearby farming, this system helps reduce that specific contaminant for safer household use. It treats water at up to 6 gallons per minute and is designed for residential and light commercial flow rates.

The problem you’re facing

Your well water shows signs of nitrate contamination. Maybe you’ve had a water test flag it, or you know farming runoff is common nearby. High nitrate levels won’t change the taste or smell much, but they show up in test results and can cause serious worry, especially if you have infants or pregnant family members. This isn’t about scale, rust stains, or sulfur smells—it’s a discrete chemical problem that standard softeners or filters don’t address.

Why nitrate shows up in your well water

Nitrate often comes from fertilizer and septic system runoff seeping through soil into groundwater. Wells drawing from this water carry the nitrate into your home. The only sure way to confirm is a lab water test reporting nitrate concentration. Nitrate levels above recommended limits signal the need for treatment.

What it costs you not to fix nitrate

Leaving high nitrate levels untreated isn’t about damage to pipes or appliances. It’s about the ongoing health risks nitrate poses to household members, especially babies. You may also face regulatory challenges if you use well water for childcare or other sensitive uses. Beyond that, untreated nitrate doesn’t harm your water heater or cause stains, but it does mean your drinking, cooking, and bathing water includes a contaminant you’ve tested for and want to reduce.

How this system reduces nitrate in your water

This system uses a process called anion exchange, which works like a chemical swap. Nitrate ions in your water are attracted to a special resin inside the system. As nitrate sticks to the resin, harmless chloride ions are released into the water instead. The resin eventually fills up and needs to be flushed clean—this happens automatically using common salt brine, much like a water softener regenerates.

What this system can handle

Rated to treat water at up to 6 gallons per minute, it suits most family homes and light commercial use. The nitrate-selective resin inside is designed to keep working even when other substances like sulfate are present, avoiding a problem called 'nitrate dumping' where nitrate could otherwise be released back into your water unpredictably. This makes the system reliable for wells affected by agricultural runoff. Before choosing it, a water test for nitrate and sulfate levels is important, as their balance affects how well the system works and how often it regenerates.

What you actually get

The system includes a pressure vessel covered by a lifetime warranty, which protects the tank against leaks or breaks. The control valve and electronic components come with the manufacturer’s standard warranty. A bypass valve is included at no extra cost, allowing you to isolate the system for maintenance while still running water to your home. Also included is 10 feet of discharge hose for the drain line, making setup more straightforward for your plumber.

Is this system the right size for you?

If your household water use fits within a flow of up to 6 gallons per minute, this system can handle your nitrate reduction needs effectively. Larger homes or small businesses with higher flow requirements should consider bigger systems tailored to those demands. Conversely, if your water flow is significantly lower, a smaller, less complex system may suffice.

Living with this system

Maintenance mainly involves periodic regeneration, where the resin is cleaned with salt brine. This process happens automatically based on your water use and nitrate load but will require refilling the salt supply regularly, similar to a water softener. Expect to have your local licensed plumber handle installation and any service needs. The included bypass valve makes servicing easier without shutting off your water supply.

What this system won’t do

This system focuses solely on reducing nitrate levels. It does not soften water or remove hardness minerals, iron, sulfur, bacteria, or other contaminants. If your water has multiple issues, additional treatment equipment may be needed to address those separately.
