If I could leave ZERO stars, I would.
I ordered a pump that advertised 400 gallons per hour. It arrived in a used box and obviously was sent back before. I put it in operation and it seems to not be pumping properly. I tested the output by filling a 2 gallon pail with a stopwatch and the output was 160 gph. I tried to return it for a full refund and 123 ponds refused saying that the problem is with the manufacturer, not them. Horrible customer service.
STAY AWAY FROM THIS STORE. THEY DON'T STAND BEHIND
