Scale management is recommended on DDC Dolphin Ltd macerators in exceptionally hard water<br />
areas where scale is known to cause issues cold water system. Approximately 70% of the water<br />
used throughout the world is naturally hard, meaning it contains a high mineral content, including<br />
calcium as well as various other salts. Calcium deposit build up can have detrimental effect on<br />
pipes, valves, spray heads and other devices within the machine. Please note components<br />
which fail as a result of scale deposits are not covered under warranty.<br />
