The company’s No Scale filters provide an economical way to protect water systems against scale and corrosion. Consisting of a balanced blend of NSF-61-approved hexa polyphosphates, this option stabilizes and inhibits the corrosion and scale process. It is slow acting, preventing new scale from forming and loosening and softening existing scale deposits. Over time, these deposits are flushed off by the natural turbulence of the water flow. This option is compatible with galvanized, copper and plastic pipes, as well as all wetted surfaces. It is available on all the company’s filter products.
