3M Aqua-Pure AP430 Hot Water Heater Scale Inhibitor System

The 3M Aqua-Pure AP430SS system installs BEFORE the hot water heater in order to filter the water before it reaches the hot water heater. This helps prevent damage to the hot water heater from scale buildup. The 3M Aqua-Pure AP430 Hot Water Filter System comes with the AP431 water filter cartridge and the 3/4-inch inlet and outlet water pipe connector. The 3M Aqua-Pure AP430 hot water filter system installs directly on the 3/4-inch pipe leading into your hot water heater. The AP430SS will extend the life of your hot water heater or tankless hot water system by stopping scale buildup and corrosion, and helps save money on maintenance costs. Features a stainless steel fitting and a consistent dose of Siliphos. Siliphos is a 100% pure food grade scale inhibitor approved by the USDA. The AP430 filter system binds calcium and magnesium hardness minerals, preventing them from precipitating out of solution and building up on metallic surfaces which helps prevent piping systems from corrosion and inhibits scale buildup in hot water heaters & water-using appliances.
