When should you attempt to repair a valve?

Attempting to repair a valve is best done when it is not under pressure because this significantly reduces the risk of injury and ensures a safer working environment. When a valve is pressurized, the potential for accidents, such as water sprays or explosive decompression, increases. Working with a depowered system allows for easier disassembly of the valve components and less chance of causing further damage during the repair process. Additionally, any residual pressure can lead to unexpected releases of the working fluid, potentially causing harm to the technician or damaging surrounding infrastructure. Therefore, addressing the valve while it is safely depressurized is crucial for both safety and effective maintenance.
