What is a characteristic of a properly maintained backflow prevention system?

A properly maintained backflow prevention system is characterized by regular inspection and maintenance records. This is important because consistent inspections ensure that the backflow prevention device is functioning correctly and meeting safety standards. These records serve as documentation that the system has been routinely checked for proper operation, which is crucial in preventing contaminants from entering the potable water supply.

Regular maintenance helps to identify potential issues before they become significant problems and allows for timely repairs or replacements, thus ensuring the device remains effective. Overall, the documentation of inspections and maintenance reflects not only compliance with local regulations but also reinforces the importance of maintaining the integrity of the water supply system.
