The 3M Whole House Scale Inhibition Water Treatment System AP430SS 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. Features include: -Flow rates up to 10 gpm/37.9 lpm-3/4” NPT inlet/outlet connections-316 stainless steel head for “sweat-in-place” installation and corrosion resistance25 – 125 psi/172 – 862 kPa pressure range40 - 100°F/37.8°C temperature rangeSystem materials are FDA CFR-21 compliant* The overall design of the scale inhibition system makes the installation and cartridge change-out easy for professionals. The 3M Whole House Scale Inhibition Water Treatment System AP430SS is to be installed on the cold water supply line of the water heater or at point-of-entry of water into the home. The scale inhibition system helps extend the life of downstream water-using appliances such as water heaters (standard and tank-less), clothes washers and dishwashing machines, as well as plumbing fixtures like faucets, pipes and shower heads by reducing scale build-up and corrosion. Polyphosphates in minute concentrations of 2-3 ppm, effectively help prevent scale build-up by inhibiting the deposition of hardness minerals onto metallic surfaces. Polyphosphates also helps prevent corrosion by forming a thin protective layer on the metal surface. The 3M Scale Inhibition Water Treatment System AP430SS is manufactured using FDA CFR-21 compliant materials* and is suitable for drinking and cooking water, and food applications. 3M branded water filtration products have been addressing water quality issues for over 50 years. 3M products offer a wide range of solutions designed to address many types of water quality concerns. Third-party certifications, such as NSF and WQA, are an advantage provided on many 3M Aqua-Pure water quality improvement solu Polyphosphates help to inhibit scale build-up in water heaters (standard and tank-less styles) and in appliances such as dishwashers and clothes washers which can help extend the life of hot water-using appliancesScale inhibition also helps protect piping from corrosionEasy cartridge change-out helps provide easy system maintenance
