Hello! I am new here, this being my first post. Am active in another forum, and sought variety. Have been working on a 1-1/2" scale Northern locomotive here in the Missouri, Ozarks, USA, for 6 years. However, this thread is not appropriate for further such discussion.
Distilled water is in my opinion the best water to use in our boilers, as it contains no dissolved minerals to form deposits within them. However, it invariably DOES contain dissolved carbon dioxide, which makes it's Ph about 5.5 to 6.0, which further means, use of such water promotes corrosion. Therefore, distilled water must have it's Ph adjusted upward, to at least 8.0 or more. This is easily done by simply dissolving a basic chemical in the water, such as potassium carbonate. Sodium bicarbonate, baking soda to our ladies in the kitchen, is adequate, but will only raise the Ph to a little under 8.0.
Cost of distilled water is fairly high. So, why not build a still? I have been making my own distilled water for several years, at about 1/3 the local cost to purchase it, which currently is about $0.80 per gallon.
Not knowing how interested members might be in building a still, I will await comment. However, please do not hesitate to ask! I am a scrounger, and as such, found that building my still was very reasonable to do.
Thank you for reading!
PS: Anyone interested in my locomotive may freely inquire about it, also!
