Part 3/7:
Another critical safety component is the pressure relief valve. This device safeguards the tank from excessive pressure buildup due to overheating. When the water heats beyond safe limits, the valve releases steam and excess pressure. However, installation errors, such as blocking the drain pipe or neglecting to install it altogether, can prevent proper pressure release. Without an unobstructed drain pipe, pressure accumulates dangerously, risking an explosion.
An alarming scenario was described where a pressure relief valve was improperly sealed, preventing steam escape. This led to an explosion so powerful that smoke and debris were widespread, emphasizing the importance of adherence to proper installation and maintenance protocols.
