What to do if your boiler loses pressure - British Gas

Boiler water treatment is done to minimize corrosion, deposition, scale, and carryover in the water–steam circuits. The aim is to maximize the reliability of the steam–water circuit. Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness.
