City hard water loaded with iron isn’t just a nuisance—it’s a silent saboteur wreaking havoc on your plumbing, appliances, and daily comfort. Stubborn rust stains darken sinks and tubs, while mineral buildup clogs pipes and reduces water flow, leading to costly repairs. Your water tastes metallic and looks cloudy, turning every sip and shower into a reminder that untreated city water is damaging your home’s value and your family’s wellbeing.

The system that fixes it

The Pentek City Hard Water + Iron System is engineered specifically to tackle the dual challenge of city hard water combined with iron contamination. At its core, the system boasts the Pentek-series air-injection control valve—a precision-engineered head valve that initiates and controls the air injection process vital for oxidizing dissolved iron before filtration. This genuine, serviceable brand valve ensures smooth, reliable operation over time with easy maintenance and parts replacement, protecting your investment and the system’s performance.

The robust build features an air-injection tank designed to treat your water efficiently by first oxidizing iron particles, making them easier to filter out. Following this pre-treatment, the water passes through a layered media bed combining iron filtration media with softening resin. By coupling these media types, the system removes iron contaminants while simultaneously softening hard minerals typical of city water supplies that carry both issues together. This all-in-one treatment helps you enjoy clean, clear water throughout your home.

How the media works

This system’s effectiveness lies in its dual-media composition: the iron filtration media captures and removes oxidized iron particles, turning clear water into iron-free water. Before this, the air-injection process converts dissolved iron into a solid form that the media can trap. After iron removal, the water passes through the softening resin, which exchanges the hard minerals such as calcium and magnesium with sodium ions, dramatically reducing water hardness. This two-step media approach ensures your water is both free from iron staining and softened to protect your home and improve comfort.
