Pump performance was ok, all connections have passed - and the pre-filter, all made a solid impression because of metal - BUT: I had every day about 1 -1.5 hours to distribute the water in the garden. The pump has been doing in 5-second intervals and off. And then this volume, despite that I had a wooden house built around it. That was so annoying, that did not work. Perhaps that part was after all broken .... Now I have a normal pump from Gardena 4000/4 Inox Multi 3: smaller (well, is not much of HWW), but just as pumped and is sooo quiet, only 68 db - perfect
