In this Weekly Boiler Tip we continue our steam trap series by breaking down one of the most common trap designs in the field: the Inverted Bucket Trap. We cover how it operates, its biggest limitations, where it performs best, and how to properly troubleshoot it using sound, ultrasonic testing, and real-world failure clues. This is required knowledge for anyone working with steam distribution, drip legs, kettles, and start/stop applications. Safety notice: Always consult experts for complex repairs.
