The liquid-filled PV breaker has acted to relieve a vacuum in a tank. What action must be taken in regards to the PV-breaker before continuing operations?
AI Explanation
The correct answer is A) Refill the breaker with liquid.
The liquid-filled PV (pressure-vacuum) breaker is designed to relieve a vacuum in a tank by allowing air to enter the tank. If the liquid in the breaker has acted to relieve the vacuum, this means the liquid level has been depleted. Before continuing operations, the breaker must be refilled with the appropriate liquid to restore its functionality and ensure it can properly respond to future vacuum conditions in the tank. The other options are incorrect because they do not address the need to refill the depleted liquid in the breaker.
