Where can you find a pressure vacuum gauge on a Type 2 hydrant system?

• A. By the defuel pump
• B. The deep well pump
• C. Upstream of the tank outlet valve
• D. Downstream of the hydrant outlet valve

Answer: (A)

In a Type 2 hydrant system, the pressure vacuum gauge is typically located by the defuel pump. This placement allows for accurate monitoring of the pressure and vacuum conditions directly associated with the operation of the defuel pump. Monitoring at this location is crucial for ensuring that the pump operates within safe parameters, preventing potential issues like cavitation that can arise if the pressure drops too low. The other locations listed do not provide the most relevant information for the specific operational needs associated with the defueling process. For instance, the deep well pump primarily focuses on the extraction of water and might not be equipped with a pressure vacuum gauge specific to the defuel operation. Similarly, being upstream or downstream of the tank outlet valve does not yield the pertinent data needed to monitor the immediate effects of fuel transfer processes linked to the hydrant's operation.
