How many test cocks does a Spill Resistant Type Pressure Vacuum Breaker Assembly have?

  1. Two

  2. Three

  3. Four

  4. One

The correct answer is: One

A Spill Resistant Type Pressure Vacuum Breaker Assembly is designed to prevent backflow and contamination of potable water systems. It is equipped with a specific number of test cocks that allow for the testing and maintenance of the assembly's function. In this case, the assembly features one test cock. This single test cock is integral to performing the necessary tests required to verify that the device is operating correctly and ensuring that back siphonage does not occur. The design and functionality of the assembly limit the number of test cocks to one, making it straightforward for inspection and testing processes. This simplicity is essential for maintaining safety and compliance with cross-connection control standards.
