The 3M Aqua-Pure AP430SS Whole House Scale Inhibition Water Treatment System is recommended in areas with turbid or hard water for standard tank water heaters, tankless water heaters, drinking fountains, solar water heaters, and boilers


≈ Includes polyphosphates to help prevent scale in both standard tanks and tankless water heaters. Also works to extend the life of hot water-using appliances such as clothes washers and dishwashers.
≈ Scale inhibition protects hot waterways (hot water pipes) from corrosion
≈ Easy to maintain with the quick change cartridges
≈ standard 3/4” NPT water inlet/outlet connections
≈ head is made of 316 stainless steel head for corrosion resistance

Description Details

The polyphosphates in the Aqua-Pure bind calcium and magnesium minerals, which are the main components of hard water. This prevents them from precipitating and building up on the appliances water-touching metallic surfaces.

The AquaPure should be installed on the cold water supply line of the water heater or other appliance. It will extend the life of downstream water-using appliances by reducing scale deposits and corrosion.

The Polyphosphates are in tiny concentrations of 2 to 3 ppm. In addition to preventing the scale build-up, polyphosphates also prevent corrosion by forming a thin, protective layer on the metal surfaces. Since the Aqua-Pure uses FDA CFR-21 compliant materials, it can be used with drinking and water for cooking food.
