These plaques can flake off, leading to visible impurities in water and a slight metallic taste.

“Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away from flammable materials), or by wrapping ...
Galvanized mild steel cable ladder with corrosion around stainless steel bolts. All metals can be classified into a galvanic series representing the electrical potential they develop in a given electrolyte against a standard reference electrode. The relative position of two metals on such a series gives a good indication of which metal is more ...
A tiny, 1/8-inch crack in a pipe can release up to 250 gallons of water a day. [3] According to Claims Magazine in August 2000, broken water pipes ranked second to hurricanes in terms of both the number of homes damaged and the amount of claims (on average $50,000 per insurance claim [citation needed]) costs in the US.
