Corrosion Advice

Even when using stainless steel vessels, corrosion can still be an issue. This can occur when units are connected to a private supply, wells or where the water has a high concentration of Chlorine (CI), in excess of 200PPM. It is the responsibility of the installer to establish the water and supply type before installations take place. In cases where the water is found to be outside these parameters additional protection against corrosion will be required, to combat this issue RM can supply a Stainless steel vessel with a built-in electrical anode, this must be specified at the time of order as a unit cannot be upgraded. Failure to follow these guidelines will invalidate the product guarantee when the unit has failed due to corrosion.
