3M Aqua-Pure AP430SS Whole House Scale Inhibition Water System

The 3M Aqua-Pure AP430SS Whole House Scale Inhibition Inline Water System is engineered to combat scale accumulation and corrosion, effectively prolonging the lifespan of hot water appliances such as standard gas and electric water heaters, tankless heaters, boilers, clothes washers, dishwashers, as well as plumbing fixtures like faucets, pipes, and shower heads. By mitigating the buildup of scale—primarily composed of calcium and magnesium minerals which crystallize in heated hard water—the AP430SS helps maintain appliance efficiency and performance over time.

Hard water is the main culprit behind scale formation, gradually reducing water flow and increasing wear on appliance components. The AP430SS tackles this issue through its incorporation of polyphosphates, which bind with calcium and magnesium ions to prevent them from solidifying on metallic surfaces. This not only inhibits scale buildup but also forms a protective layer that reduces corrosion, thereby extending the operational life of appliances and plumbing.

Certified by NSF International to NSF/ANSI Std. 42 for material and structural integrity, the AP430SS features a single vessel design that facilitates easy replacement of the 3M Aqua-Pure AP431 water filter cartridge, recommended every six months or sooner if there's a noticeable decrease in water flow rate. Installation involves connecting the system to the cold water supply line of the water heater or at the point-of-entry into the home using standard 3/4” NPT connections.

To install the AP430SS, additional tools and parts are necessary but not included: a 3/4” compression type stop and waste valve, PTFE tape, two 3/4” male x 3/4” street adapters, a 3/4” compression gate valve, and a pipe cutter. It's crucial to carefully follow the installation instructions provided, ensuring proper fitting and compatibility with existing plumbing infrastructure.

The system's stainless steel head ensures durability and longevity, capable of sustaining a flow rate of up to 10 gallons per minute (37.9 liters per minute), making it suitable for typical household water demands. It can accommodate various pipe sizes through optional adapter fittings, allowing flexibility in installation with copper, galvanized pipe, or PEX tubing.

In operation, the AP430SS diverts a small portion of water through the cartridge, where polyphosphates are introduced in minute concentrations before returning to the main water supply. This process aids in reducing scale formation without compromising overall water flow or pressure, crucial for maintaining efficiency in water heaters and other appliances.

Moreover, the AP430SS includes Siliphos, a USDA-approved, 100% pure food-grade scale inhibitor, enhancing its effectiveness in preventing mineral buildup on metallic surfaces. With a maximum operating temperature of 100°F (37.8°C) and a flow rate of 6 gallons per minute, it ensures reliable performance under typical household conditions.

In summary, the 3M Aqua-Pure AP430SS Scale Inhibition Inline Water System offers an efficient solution to combat scale buildup and corrosion, safeguarding both water-using appliances and plumbing fixtures while maintaining optimal water flow and efficiency throughout the home.
