Rosette corrosion
The Illustrated Guide to Hot and Cold Water Services (BG 33/2014), written by Reginald Brown and published by BSRIA in 2014, in relation to rosette corrosion, it states: ‘This type of corrosion occurs in the base of cylinders fitted with aluminium anodes. In principle the sacrificial anode is supposed to protect the cylinder from corrosion but in certain water chemistries at temperatures below 40°C it has the opposite effect. New copper cylinders do not use aluminium anodes and should not be at risk.’
