great pump-poor packaging

Would Recommend

Ordered online, thing weighs like 20 lbs and they wrapped it with a piece of brown paper and put it in a small box. Arrived banged up pretty good, the electrical box was crushed. Had to straighten it back out to use. Needed much more than a piece of paper for packing material. Otherwise, its working well.
