Where can a pressure vacuum breaker be installed within a building?

• A. Must be within 5 feet of a floor drain
• B. Must be within 10 feet of a floor drain
• C. Is not allowed
• D. Must be in a ventilated area

Answer: (C)

A pressure vacuum breaker is a type of backflow prevention device specifically designed to protect the potable water supply from contamination. It is crucial for these devices to be installed correctly to ensure their effectiveness and compliance with plumbing codes. The correct response indicates that a pressure vacuum breaker is not allowed to be installed within a building. This is due to the fact that pressure vacuum breakers must be installed in an outdoor setting or in a location where they are subjected to atmospheric pressure, which is essential for their proper functioning. Inside a building, they could be at risk of being submerged or have backpressure applied, which would negate their intended purpose. For the other options regarding installed proximity to floor drains: it is not suitable to define pressure vacuum breaker installations by proximity to floor drains when they cannot be found inside at all. Similarly, there is no requirement for placement in a ventilated area if installation is outside and compliant with external conditions. Understanding these specifics helps ensure that plumbing professionals make informed decisions that align with the established codes and maintain safe water systems.
