What is the consequence of not properly sealing the valve between the boiler and the water column?

Failing to properly seal the valve between the boiler and the water column can lead to increased safety risks due to the potential for pressure imbalances or water hammering. The water column is a crucial component that provides a means of measuring the water level in the boiler, which is essential for safe operation. A poorly sealed valve can allow steam or hot water to escape, which may diminish the effectiveness of the safety controls that prevent the boiler from operating under unsafe conditions.

Moreover, if the connection is not secure, it could lead to inaccurate readings of the water level, creating an environment where the boiler could run dry or overpressurize, both of which pose significant hazards. Therefore, ensuring that all connections, including the valve between the boiler and the water column, are properly sealed is paramount for maintaining the integrity and safety of the boiler system.
