Leak testing of pressure vessels and piping systems may be required by an inspector. The To safely pressurize a system for a leak test: the system's pressure must be gradually increased to a required test pressure (provided by the inspector) the test pressure must be maintained for a designated period of time, generally between
The necessary actions are to have a manual oil pressure test ran on this engine, asap. When running a manual oil pressure test, you will discover if the true oil pressure is low, or normal. If the test proves that the oil pressure is, indeed, low, this will confirm that the Oil pump is suspect.
The trained boiler attendant need not be permanently situated in the boiler house but must be able to respond immediately to the level alarms.
