AlphaWorks Water Transfer Pump 7HP 196cc 4-Stroke (Open Box)

Got this pump to lower the water level in my pool. I also purchased the hose kit, which is necessary if you're going to use the pump on your pool. The only sort of tricky part was priming the pump. You not only have to fill the pump with water, but I found that I had to dip the intake hose into the pool to also fill it with water, because the little bit of water poured into the pump gets pumped out before the pump can create enough suction to pull water up the empty hose. Once I filled the hose with water by dipping the hose in the pool, it worked great. It sounds like a lawn mower when pumping, so you might want to wear ear protection. It lowered the water in my 25x45 pool about 20 inches in about 30 minutes.
