Description

installation system and switching valve designed for this purpose Description field of the invention The invention relates to an installation system with a filter candle for water treatment. The invention also relates to a switching valve which is designed for such an installation system. Background of the invention The published patent application DE 10 2020 128 216 A1 shows an installation system with a filter candle. This includes a bypass that directs the water past the filter candle. Using radio-controlled switching valves, the system can be temporarily put into a state in which the incoming water is directed over the filter candle. In this way, treated, particularly softened water can be temporarily withdrawn at the point of use in a simple manner if it is needed, for example, to prepare a hot drink or to water plants. task of the invention Compared with the prior art described above, the object of the invention is to provide such a system with bypass in which the integration and installation of the corresponding components is simplified. Summary of the Invention The object of the invention is already achieved by an installation system and by a switching valve according to one of the independent claims. Preferred embodiments and developments of the invention can be taken from the subject matter of the dependent claims, the description and the drawings. The invention relates to an installation system which comprises a connection head with a filter candle. The connection head has an inlet and an outlet. The connection head is used to insert the filter candle. Water can be passed through the filter candle via the connection head. The filter candle can be designed as desired. The filter candle is used to treat the incoming water. In particular, the filter candle can comprise a material, for example an ion exchange material for softening the incoming water. The filter candle can also comprise media for adding minerals. The filter candle can also contain media for disinfection and for removing pollutants, such as activated carbon. The installation system also includes a switching valve. The switching valve has an inlet via which it can be connected to a water connection on site. The switching valve also has an outlet for connecting a withdrawal point, in particular a water tap. Inlet and outlet can in particular be designed as connecting pieces for a connecting piece of a pipeline. The switching valve is therefore installed inline in the water pipe. In a basic state, the switching valve directs the incoming water, namely the water from the water connection, directly to the extraction point. In the basic state, the switching valve thus forms a bypass, which directs the water directly to the extraction point without it being treated via the filter candle. The switching valve is also connected to the connection head via two lines, namely via another output and another input. The switching valve therefore has four connections and is installed inline in the water pipe via an input and output and connected to the flow and return of the connection head of the filter candle via another input and output. The four connections are arranged on a single housing of the switching valve. The switching valve further comprises an actuator, whereby by activating the actuator water can be directed from the water connection via the connection head through the filter candle. The actuator can be designed in particular as a magnetic actuator. The actuator can temporarily direct the incoming water through the filter candle and then to the extraction point instead of via the bypass. In this way, the installation system can be temporarily put into a state in which the water is treated. The fact that all of the required components are integrated in a single switching valve enables particularly simple design and installation. In particular, an existing installation system can also be easily retrofitted with a filter candle via the switching valve in order to redesign the installation system in such a way that water is only temporarily passed through the filter candle. The switching valve can preferably be controlled wirelessly, for example via an electronic mobile device such as a smartphone and/or via a radio switch. In a further development of the invention, the switching valve comprises a water meter. The water meter can in particular be arranged in a connection piece of the switching valve. For example, the water meter can comprise an insert which is inserted, in particular clamped, into the connection piece. The water meter can in particular be designed as a turbine wheel meter, in which the axis of a turbine wheel is aligned coaxially to the connection piece. The water meter can be used to easily determine whether water is being drawn at the point of use. The water meter can be arranged in particular in the outlet nozzle. Using a corresponding signal from the water meter, it is possible to record when the water tap is opened
