First my QD pumps have been 100% amazingly quiet for the last 6 months or so...up until today. Yesterday, my mp60qd started becoming much more audible (from barely perceptible at full power to hearing it across the room as a low hum sound).
At first I thought the wet side was the issue, pulled it off, did the vinegar soak, but still making humming sound. Then I realized it is the dry side making the hum. Even with the wet side disconnected, it makes the same hum.
Is there a trouble shoot for this?
