There is little one can do when there is a terrible storm and your sump pump dies at 2AM in the morning. That's exactly what happened to me several years ago and my basement flooded. That's why I got this pump as a spare. this pump boast of moving 6000 GPH, that's a lot of water. Take into mind that it can pump that much if it's 0-4 feet at total feet of lift. But even at maximum lift of 33 feet, it is still capable of of pumping 3,400 GPH. (Gallons Per Hour) In my book that is one powerful pump. This pump is strictly designed for sump pump applications, so don't try to use it as a waterfall pump or a pool pump.I like the float bracket design as that seem to work best in my basement. As the water raises when it hits the top, it automatically switches on and just begins sucking that water out until the float settles to normal. I always make sure I clean out the pump every couple of month as not to get it clogged with silt or other debris. Looking at the suction area at the bottom of the pump is a much larger grate than I've seen in others. Another good idea to allow more water and miniscule debris to flush through.I feel more secure knowing I have a backup if and when the current pump gives out. And they will eventually. This is a excellent buy and I recommend that if you have a sump pump that IS working, get yourself this Vevor 1.5 HP Submersible pump for a backup. And if you need a sump pump, get this one now. You'll thank yourself when it happens. And like I said "it will".
