How frequently should check valves be inspected in a refrigerant system?

The correct approach to inspecting check valves in a refrigerant system is during every maintenance check. Regular inspections during maintenance are vital because check valves play a crucial role in preventing the backflow of refrigerant in a system. If a check valve fails, it can lead to system inefficiency, potential contamination, and even equipment damage.

By incorporating inspections of the check valves at every maintenance interval, technicians can identify issues early, ensuring the system operates efficiently and prolonging the life of the equipment. This proactive measure helps maintain the integrity of the refrigerant cycle and supports overall system reliability.

Infrequent inspections, like yearly or only after a failure, can lead to unexpected system failures or decreased efficiency, emphasizing the importance of making check valve inspections part of routine maintenance practices.
