i still cant believe how well this pump is made. i brought this to replace my pentair whisperflow 3/4 hp. the installation was easy, just cut the pipe, remove old one and connect the new one. its VERY quiet, much quieter than my old pentair before it went bad. it seems to move less water(maybe should had buy 1.5) but after a month of use it doesnt seem to be a problem. for a quarter of price of a pentair, i would def buy again.update:Since it's been a bit over 2 1/2 years i like to give this review a update. The pump still working like new, it has enough power for my pool and it is still very quiet compare to my old whisperflow. want to give a shout out to the company that make this pump, good price without sacrificing quality. i will buy again once if one go out. at this point i will be happy even if it die tomorrow since i got a good 2 1/2 years out of it. consider a quarter of price compare to a known brand i still come out ahead.
