Nothing ruins the look and feel of clean water like stubborn orange iron and rust stains. These unwelcome orange-brown marks invade sinks, showers, toilets, and laundry, turning white fabrics dingy and leaving your fixtures with a constant rusty haze. Beyond aesthetics, iron and rust build-ups corrode plumbing, damage appliances, and leave your entire home vulnerable to costly repairs and frustrating maintenance headaches.

The system that fixes it

Say goodbye to orange iron and rust stains for good with the Pentek Orange Iron & Rust Stains System, engineered specifically to target and eliminate the root cause of rusty water problems. At its core, this system features the advanced Pentek-series air-injection control valve — a genuine, serviceable valve designed to effortlessly manage the precise air injection needed to oxidize iron particles. This valve ensures your system runs smoothly, allowing continuous regeneration cycles that flush away contaminants without wasting water or media.

The system’s backbone is its air-injection oxidizing tank, carefully designed to create an air pocket inside the media bed. This pocket initiates oxidation, converting dissolved iron into solid particles. These particles get trapped by the Katalox Light oxidizing media, a powerful filtration material built to capture and then backwash iron out of the system, preventing buildup and keeping water crystal clear.

• Pentek-series air-injection control valve: precise air dosing for superior iron oxidation.
• Air-injection oxidizing tank: engineered for maximum contact with air, accelerating iron transformation.
• Katalox Light oxidizing media: traps oxidized iron particles effectively, ensuring long-lasting iron removal.
• Easy maintenance: genuine, serviceable valve parts mean repairs and upkeep are straightforward, extending system lifespan.
• Backwash cycle: flushes trapped iron out of the media, restoring filtration capacity without hassle.

What it does for your home

• Eliminates orange rust stains on sinks, tubs, toilets, and showers, restoring spotless surfaces.
• Protects plumbing from corrosion caused by dissolved iron deposits, extending pipe life.
• Prevents discoloration of laundry, preserving fabrics and colors.
• Improves water clarity and taste by removing metallic iron particles.
• Reduces maintenance and replacement costs on water-using appliances like water heaters and dishwashers.
• Supports healthier skin and hair by removing iron-related impurities that cause dryness and irritation.

These benefits combine to transform your home into a clean, protected living space free from the nuisance and damage of orange iron and rust stains.

How the media works

The heart of this system is the Katalox Light oxidizing media, a specially engineered material designed to trap iron after it’s transformed by oxidation. Here’s the process in simple terms: The air-injection valve introduces air into the tank, creating a small air pocket inside the media bed. This oxygen-rich environment turns dissolved iron into solid particles — tiny rust bits. Then, the Katalox Light media acts like a magnet, catching those particles as water flows through. Over time, the system backwashes, flushing out the trapped iron so the media stays fresh and effective. This clever combination of oxidation and filtration means your water is constantly purified, free from rusty contaminants.
