    Lower the actual boiler water level to the 1st low (by evaporation), and then blow down to the 2nd low. The main reason for this weekly test is to ensure that the alarm is given, and at the correct level, when the level drops slowly in the boiler (because floats could stick). 2. A high alarm is usually tested weekly.

    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.
