    How to unclog the drain in my Tuttnauer EZ10?
    • P
      Paul GarciaAug 22, 2025
      To unclog the drain in your Tuttnauer Laboratory Equipment, open the drain by turning it counterclockwise. Place a heavy object over the reservoir cover. Blow compressed air into the drain to force any debris back into the reservoir, and then clean out the reservoir. Alternatively, disassemble the drain valve by turning it counterclockwise past the stop point. Remove the valve, clean it, and blow out the line as needed. Reassemble the valve by turning clockwise, ensuring the large “O” ring is pressed into the groove on the autoclave.
