Review on SumpMarine Water Transfer Pump, 115V - Efficient 330 GPH Portable Electric Utility Pump with 6' Water Hose Kit - Perfect Solution for Removing Water From Gardens, Hot Tubs, Rain Barrels, Pools, Ponds, Aquariums, and More! by Mufti Capers

I ignored the other reviews here and bought it anyway. I wish I hadn't. I followed the instructions in the priming and lubricating guide. It worked fine the first time. The second time, no water was taken from the spring. It didn't need to be lifted (the pump was flush with the tank it was trying to pull from), it just wouldn't pull. I refilled and lubricated the pump and it worked. Third time same, except he didn't tug on it after opening it to pour. I filled the entire suction hose several times and finally it started to draw water. The fourth time he did nothing to get him to vote. Do not buy this pump!
