If there is no automatic drain, when should you drain the air tanks?

After every working day.
After every four hours of service.
Once a week.
Every other week.

The correct answer is: After every working day.

Draining the air tanks daily after every working day is crucial for maintaining the proper functioning of air brake systems. Over time, moisture accumulates in the air tanks as a natural byproduct of compressed air. If this moisture is not drained regularly, it can lead to corrosion of tank components, reduced air efficiency, and potential brake failure due to the freezing of moisture in colder temperatures. Daily maintenance, including the draining of air tanks, ensures that the air brake system operates effectively and safely, reducing the risk of air-related issues while driving. Regularly performing this task is part of a comprehensive safety and maintenance protocol, ultimately contributing to safer driving conditions and improved vehicle performance.
