When the water was tested it proved the water company were adding chalk amongst other things into the mains water!!!

I have heard of the acetic acid in the tender treatment, but never had the need to try it. In Birmingham, we have the softest water in the country, straight from the Elan Valley in Wales, never de-scaled a kettle yet.... Including a railway kettle!! Dave. MODEL ENGINEERING DISCUSSION LIST.
