How often must the tanks be drained to prevent contamination from accumulating?

Draining the air brake tanks every day is important in order to prevent the accumulation of moisture and contaminants within the air system. When moisture collects in the tanks, it can lead to several problems, including corrosion of internal components, freezing in cold temperatures, and ultimately damaging the air brake system's efficiency and effectiveness. Daily draining ensures that any accumulated water and contaminants are removed before they can cause significant issues.

While some drivers might consider draining the tanks less frequently, such as weekly or monthly, this can increase the risk of damage or failure due to unaddressed moisture buildup. Therefore, the most effective practice is to drain the air brake tanks every day to maintain optimal functioning and reliability of the braking system.
