What is likely to happen if a joint does not pass the visual inspection after soldering?

When a joint does not pass the visual inspection after soldering, it indicates that there may be faults such as insufficient solder, poor joint fit, or contamination, among other potential issues. A failed visual inspection typically signifies that the joint may not provide a proper seal and could lead to leaks or failures under operational conditions. Thus, the appropriate action is to rework the joint to ensure that it meets the necessary quality and safety standards before it is put into service. Ensuring that all joints pass visual inspection is essential for maintaining the integrity and reliability of the plumbing system.
