Water treatment for iron boiler? - The Home Machinis

2018-12-16·Since it is iron, it is of course prone to rusting, and when I drain it there is a slight rusty brown tinge to the water. Should I be using some kind of water treatment? Or is it not worth it for a boiler of this size, and I should just keep an eye on any rust and do a hydrostatic test every so often?

How to Test for Iron in Water | Hunk

This carries the iron into the water supply as ground water seeps into aquifers. Iron can be found in drinking water as ferrous iron which is soluble and ferric iron which is insoluble. You can determine if you need to have the iron concentration in your water measured by observing its color and other properties.
