the acidity of water on the harm of boilers
Nov 29 2012 · A change of 1 pH in pH scale represents a change of 10 times of relative alkalinity or acidity i.e. a pH of 4 is 10 times more acidic than a pH of 5. Having learnt the basics of water lets now take a look at the problems and impurities associated with water.

The corrosive nature of acidic water causes metal ions such as iron manganese copper lead and zinc to leach into the water causing elevated levels of toxic metals in your water. Signs of acid water are corrosion of fixtures blue staining (from copper pipes) or rust staining (from iron pipes). Acidic water can also cause pinhole leaks and pipe failure over time. It may also cause aesthetic problems such as a

Dear HB Espresso Lovers Hobbyists and Mad Geniuses Regarding water use and setup of the Elektra Microcasa Semiautomatica (my very recent impulse buy--woohoo!) this suggestion from the buying guide makes a lot of sense: I do have one suggestion-initially fill the boiler with reverse-osmosis (RO) or distilled water. The boiler fill is manual so no minerals are required and the...

Low make up feed water pH can cause serious acid attack on metal surfaces in the preboiler and boiler system. Feed water can also become acidic from contamination of the system (process contamination of condensate or cooling water contamination from condensers). Acidic corrosion can also be caused by chemical cleaning operations (overheating of the cleaning solution excessive exposure of metal to
