Pepper pot 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 pepper pot corrosion, it states: ‘This is a form of microbially influenced corrosion (MIC) that occurs under biofilm in the lower part of the cylinder, particularly around the cold water inlet at the base of the cylinder, where the water remains relatively cool. It results in a large number of closely spaced pits (hence the pepper pot description) with general thinning.’
