Received pump July 21, 2023. Reviewed operations, had to secure a Jon Boat to set 10” aerators to pond, That took a couple weeks. Have been running pump 24/7 for a couple weeks now. The Black Box that houses the toggle vibrates and makes more noise than the pump. I was able to dampen a bit by wedging a shim under. Bout a week ago I noticed one aerator was boiling the water which was definitely different from what it had been doing, away retrieved aerator and found that the 10” dome had broken off, I put it back figuring bubbles are aerating. This morning 8/31 drove down to pond to feed fish and pump was off. Note: The pump is plugged into an extension cord that is running to an Exterior outlet with dedicated breaker so I have not had to use the toggle switch to turn it on and off. I built a free standing roof over the platform I built to hold pump to keep pump out of the weather. Its opened on all sides for ventilation. I checked the toggle to make sure it was in the on position and when I did the pump started, ran for about thirty minutes and has now stopped again. Toggle does not feel right.
