The Aqua-Pure™ AP430SS hot water system protector is one of the most popular domestic hot water purifying systems, particularly for households with hard water. The system works by de-scaling the cold water source to hot water storage tanks. The system's impressive descaling properties, provided by a Aqua-Pure™ AP431 filter, is ideal for households feed water with high calcium and magnesium content.

The 3M™ AP430SS Whole House Scale Inhibition Water Treatment System 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:

304 stainless steel head for "sweat-in-place" installation and corrosion resistance
25 — 125 psi/172 — 862 kPa pressure range

The overall design of the scale inhibition system makes the installation and cartridge change-out easy for professionals. The 3M™ AP430SS Whole House Scale Inhibition Water Treatment System should be installed on the cold water supply line of the water heater or at point-of-entry of water into the home or light commercial application. 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.

Effective for all types of hot water systems, including boilers, tank-less, and tank-type (electric and gas) water heaters, as well as whole-house and commercial humidifiers.
