The pressure test has to be made by adding an inhibitor to the water during pressure test. After
pressure test of the boiler, the water is drained and a powdered inhibitor is added. E.g. Cortec
VCI-609, or other corresponding product. The dosing of the inhibitor has to be checked
from the manufacturer’s manual. After adding the inhibitor, all open joints and holes have to be
closed.
