Best Hot Water Heater For Hard Water (2024 Updated)

The 3M Aqua-Pure AP431 System is a scale reduction system that helps to inhibit the build-up of mineral scale in pipes and water using appliances. It uses polyphosphates to bind calcium and magnesium hardness minerals and prevent them from becoming solid. This helps to protect hot water heaters and extend the life of water-using appliances, plumbing fixtures, and pipes. The system diverts only a small portion of water passing through the system head into the cartridge to inject polyphosphates in minute concentrations and return it to the water supply to help reduce scale build-up. Polyphosphates also help reduce corrosion by forming a thin protective layer on the inner-surface of pipes. By inhibiting scale build-up on heating elements, it helps maintain water heater efficiency. The AP430SS provides unrestricted flow of up to 10 gpm (37.9 lpm) when installed with 3/4” NPT inlet/outlet connections. The system is designed to be installed on the cold water line feeding water to the water heater. The easy change-out of the 3M Aqua-Pure AP431 Replacement Water Cartridge makes system maintenance easier. However, additional parts and tools are required for installation and not included. Please read all instructions carefully and measure your cold water line feed pipe before attempting to start installation.
