What is a critical step that must not be overlooked before operating the system?

Final inspection of the connections is crucial before operating any system. This step ensures that all connections are secure and leak-free, which is essential for the safe and effective operation of the system. A thorough inspection helps to identify any potential issues that could lead to system malfunctions, leaks, or even damage to the equipment and surrounding areas.

Inspecting connections allows the technician to verify that all components are properly assembled and that there are no loose fittings, which could result in water leakage. This is especially important in systems that handle water treatment or purification, as even a small leak can compromise the quality of the water or lead to equipment failure.

While setting the bypass valve, connecting the drain line, and informing the homeowner are all important tasks, they do not substitute for the necessity of a final inspection. Ensuring that all connections are secure directly affects the safety and functionality of the entire system, making it a critical step that must be performed before operation.
