What should be avoided to maintain the integrity of a pressure vacuum breaker?

Using acidic cleaning agents
Regular pressure testing
Periodic inspection for wear
Keeping it free from obstructions

The correct answer is: Using acidic cleaning agents

To maintain the integrity of a pressure vacuum breaker, it is crucial to avoid using acidic cleaning agents. Acidic cleaners can corrode and damage the internal components of the vacuum breaker, including seals, springs, and other materials that are typically designed to withstand specific chemical conditions. Such damage can lead to leaks or failure of the device, compromising its function of preventing backflow and protecting the potable water supply. In contrast, regular pressure testing, periodic inspection for wear, and keeping the device free from obstructions are all practices that contribute positively to the maintenance and effectiveness of a pressure vacuum breaker. These practices help detect potential issues before they develop into serious problems, ensuring that the device operates correctly and maintains its integrity over time.
