Quality product
By Real Engineer (from Reno, NV) on 8/4/2016
I just received and tested my pump and it worked right out of the box without any problems and moves a lot of water with great pressure. It is also very quiet considering the amount of water it pumps. These people obviously take pride in their products and workmanship. The pump is well built using quality materials and construction methods. I can't find anything to be concerned about with the pump itself and I hope it will have a long, trouble free life. I would like to see the locked rotor current included in the manual so I can know what size breaker to use on the electric service.
