<p>A description is given of a pressure sewer system and a work method in which water collected in a well is normally pushed through an outlet by means of a pump mounted on guides in the well, via a pump-specific coupling and footing coupling mounted on it. When removing the pump, the pump-specific coupling is also removed from the footing coupling and removed. A bypass is connected to the footing coupling that is held against it liquid tight by clamp units supported against the guides, possibly sprung. In particular, a removable bypass is installed on a flat connection of the footing coupling that is connected to the discharge side of an external auxiliary pump, and guides mounted in the well against which clamp units are supported that hold the bypass and that press it against the flat connection of the footing coupling to produce a liquid tight seal.</p> |
