Maintaining a proper water level in the boiler is critical. This is done by observing the water gauge and adjusting the amount of water in the tank accordingly. The water level should be visible on the water gauge at all times. This range typically shows between 75% and 85% of the boiler height, which is the intended range of operation. Blowdown valve is used to dump water from the boiler, while the injector is used to add more. Having the water level above the gauge leaves less than optimal room for steam to generate in and may overflow to the cylinders, potentially causing major damage. Having the water level below the gauge can be even more catastrophic. If the firebox is sufficiently hot and its top surface (known as “crown sheet”) protrudes above the water level, it can melt, causing the pressurized boiler to explode.
When running {{pll|Steam Overview|steam engines}}, the most critical responsibility is to maintain a nominal level of water in the {{pll|Boiler|boiler}}. This is done by observing a water gauge and adjusting the water level accordingly. The water level should always be visible within the water gauge, typically ranging between 75% and 85% of the boiler height.

When running steam engines, the most critical responsibility is to maintain a nominal level of water in the boiler. This is done by observing a water gauge and adjusting the water level accordingly. The water level should always be visible within the water gauge, typically ranging between 75% and 85% of the boiler height.
