Get this! I have not been able to time the pumps down to prevent over-filling the bags. When I hit the low stop on the timer and still could not stop the pumps, I decided to time the fill/empty times. Recall these are new 1280lb sacs. 2 min 50sec fill time. 3 min 30sec empty.

These pumps with 1-1/2" piping are screamers!!
