High nitrate and nitrite levels in well water aren’t just a numbers issue—they trigger real problems for your household. From a metallic or bitter taste in drinking water to increased health risks, especially for infants and pregnant women, these contaminants undermine your family’s safety and comfort. Left untreated, they can cause costly damage to plumbing and appliances, while quietly threatening your peace of mind every time you turn on the tap.

The system that fixes it

The Pentair Nitrate & Nitrite (Well) System is engineered explicitly to combat the dangers of nitrate and nitrite contamination in your home’s well water. At its heart is the advanced Pentair-series metered control valve—a sophisticated yet serviceable valve that precisely monitors water flow and regeneration cycles. This control head valve ensures your system operates efficiently without wasting resources, extending the life of the media and delivering consistent water quality. Paired with a specialty ion-exchange tank, the system uses a nitrate-selective anion resin media designed to selectively remove nitrate from your water even when sulfate levels spike, something many lesser systems cannot guarantee.

How the media works

The core of nitrate removal is the nitrate-selective anion resin inside the ion-exchange tank. This specialized resin works like a magnet, seeking out nitrate and nitrite molecules and binding them tightly onto its surface. What makes it exceptional is its ability to do this even when your water contains high sulfate levels—a common challenge in well water—without letting sulfates displace the captured nitrates. Over time, as the resin becomes saturated, the system’s metered control valve initiates a regeneration cycle, flushing the resin clean and readying it to protect your water once again. This ion-exchange process ensures that you receive pure, nitrate-free water reliably and efficiently every day.

Common questions

Q? How do I know if my well water has dangerous nitrate or nitrite levels?

A Testing your water through a certified laboratory is the only way to confirm nitrate and nitrite presence and concentrations. Signs like a bitter or metallic taste, or having an infant at home, make testing especially urgent.

Q? Can this system handle fluctuations in sulfate concentrations in my well water?

A Yes. The nitrate-selective anion resin is carefully formulated to hold nitrate firmly even when sulfate spikes, ensuring consistent nitrate removal without interference.

Q? How often does the system need maintenance or media replacement?

A The Pentair metered control valve triggers automatic regeneration only as needed, extending media life. Routine checks and professional service will keep the system performing at its best for years.
