Noritz Releases Enhanced Scale Shield Water Treatment

By reducing limescale, the new Scale Shield boosts the unit’s longevity while also minimizing scale build-up in other plumbing fixtures and fittings.

Noritz has released an updated version of its hard water-treatment product, Scale Shield.

The original Scale Shield aids in preventing the build-up of hard water minerals while eliminating the need for a water softener. Hard water contains dissolved calcium and magnesium that, when heated, are released in the form of a chalk-like material. This chalk coats pipes, fixtures, and fittings, creating an insulating layer that leads to lower efficiency and system malfunction.

Installed in the water heater’s water supply line, Scale Shield uses a polyphosphate material to sequester calcium before entering the water heater, preventing limescale from forming.

By reducing limescale, the new Scale Shield inevitably boosts the unit’s longevity while also minimizing scale build-up in other plumbing fixtures and fittings.

In addition, IAPMO/ANSI Z601 was created to enable testing on means and methods used to reduce scale in residential water heaters. A minimum of 70% reduction in scale formed in a hot water heater and downstream piping is required. The glassy polyphosphate used in the enhanced Scale Shield passed the IAPMO/ANSI Z601 Standard with 86% scale removal.

The updated Scale Shield is sold in a kit (SS-HB-3)  and includes a wall bracket, wrench, lubrikit, pressure gauge, and one HBC-3 cartridge.
