Have been a few weeks, the pump and am highly satisfied! Both the processing and performance exceed my expectations. In addition, the pump is in the price range of domestic water works, but by no means have this power and also even produzierien a significantly higher noise level. The deep well pump is practically inaudible! (Installation depth about 9m) also makes the electrical cable, despite its unusual appearance (ribbon cable), a solid impression and the necessary self-wiring the switch box is even for a layman not a problem. All is well beschieben. I can only guess this purchase, even if the manufacturer is perhaps unknown. I think that the pump provides a good alternative to more notable manufacturers, but certainly twice are threefold demand Pries.
