Exactly what I ordered, shipped quickly. Takes only 2 minutes to attach 4 arm bolts, then tighten the set screws to attach the shaft. Easy to plug it in and then you're done..
The Alpha Air aerator arrived on-time, and is operating wonderfully. The motor is much quieter than the original aerator that was installed in the system, and the quality is much better as well. I would recommend this item.
The product itself has been working fine but it hasn't even been a week so we shall see
very good replacement pump for aeration of my septic tank
