Water contains minerals and these minerals react with the inside of the pipe to produce the by-product. This chemical reaction between the pipe and water is a normal and natural process. This process can occur on the inside of the pipe and prevent an adequate volume of water flow. The flushing process removes much of this by-product which is why it is done annually.
