Sample interview questions: What methods do you use to troubleshoot and diagnose water treatment system issues?
Sample answer:
-
Visual Inspection: Thoroughly inspecting the water treatment system is the initial step in troubleshooting. Look for leaks or signs of damage on pipes, valves, tanks, and other components. Check the condition of filters, cartridges, and membranes for clogging or wear.
-
Water Quality Testing: Conduct a comprehensive water quality analysis to assess the performance of the treatment system. Measure parameters such as pH, hardness, total dissolved solids (TDS), chlorine, iron, bacteria, and other contaminants. Compare the results with the desired water quality standards to identify specific issues.
-
Flow Rate and Pressure Evaluation: Check the water flow rate and pressure at various points in the system. Low flow rates or pressure drops can indicate blockages, clogged filters, or malfunctioning components. Pressure that is too high can strain the system and cause leaks or damage.
-
Electrical and Mechanical Checks: Inspect all electrical connections, wiring, and switches for proper functionality. Verify that pumps, motors, and other mechanical components are operating correctly. Listen for unusual noises, vibrations, or signs of wear.
-
Service and Maintenance History: Review the service and maintenance records of the water treatment system. Check for scheduled maintenance tasks, filter replacements, and any previous repairs or modifications. This history can provide valua… Read full answer
