What is the purpose of a drain test in a fire sprinkler system?

The purpose of a drain test in a fire sprinkler system is to ensure that the system can drain properly. This test is crucial because it verifies the integrity and functionality of the system's drainage components. Proper drainage is essential to prevent water stagnation, which could lead to corrosion, or other issues that may compromise the system's performance. A successful drain test confirms that the water can be evacuated effectively, ensuring that any maintenance or inspections can be conducted without hassle.

While testing for leaks and checking the alarm system functionality are important aspects of fire safety, they are not the primary focus of a drain test. Similarly, measuring water temperature is relevant in certain contexts but does not pertain directly to the purpose of the drain test.
