The 3M™ Aqua-Pure™ Whole House Scale Inhibition Replacement Water Treatment Cartridge AP431 contains polyphosphates to bind calcium and magnesium hardness minerals, preventing them from precipitating out (or becoming a solid) and building up on metallic surfaces such as water heaters and plumbing fixtures like faucets, pipes and shower heads. The single cartridge design has a maximum operating pressure of 125 psi /862 kPa, operating temperature of 100°F/37.8°C and a maximum flow rate of 10 gpm/37.9 lpm.
The overall design of our scale inhibition system helps to make installation easy. The 3M Aqua-Pure Whole House Scale Inhibition Replacement Water Treatment Cartridge AP431 should be installed on the cold water supply line of the water heater or point of entry of water into the home. This cartridge helps extend the life of down-stream water-using appliances such as water heaters, both standard and tankless, clothes washers and dishwashing machines, as well as plumbing fixtures like faucets, pipes and shower heads, from scale build-up and corrosion.
