Thanks to the reviewers!

Have because of the positive reviews I now bought this pump. All screwed, also installed a check valve in the suction line so that the pump runs at any time by pressing a button. This part brings his little 600 W motor, a good performance, sufficient to two sprinklers and to provide a washing machine properly. My Gardena, unfortunately broken (by own debt) has been only marginally more with a 800W motor, as though looked elegant, was a little quieter, but also cost more than three times. Am now with what I got for my money absolutely satisfied. And for 1000 times thanks to Amazon for the lightning delivery!
