What should be assessed before performing maintenance on a water system?

Before performing maintenance on a water system, it is essential to assess the expected performance standards as this provides a benchmark for how the system is supposed to operate. Understanding these standards enables the technician to determine if the current performance falls within acceptable ranges and to identify any deficiencies or areas that require attention. By comparing the system's operational performance against these standards, technicians can make informed decisions regarding necessary maintenance actions, ensuring the system operates efficiently and effectively.

While factors such as the cost of replacement parts, system warranties, and the type of water being treated are also important considerations in the overall maintenance process, they do not directly inform the immediate steps necessary for maintenance based on the system's performance. The expected performance standards specifically guide adjustments, repairs, and overall maintenance strategies, making them crucial for maintaining optimal system functionality.
