Apr 11, 2017 · To begin the test, a hydro pump is used to help fill the boiler with water. The water is pumped into the vessel to the maximum allowable working pressure (M.A.W.P.) and brought to 1.5 x the M.A.W.P. It is recommended to not use cold water to hydro test a boiler. If you use cold water it will cause the metal tubes to shrink and leak.
