Drinking water supply module for drinking water circulation at closed filling stations

摘要

In the case of a drinking water supply module (10) for bridging a water meter (40) at a closed filling station (12, 14) a secondary circulation line (18, 20) of a housing unit (22, 24, 26, 28) in a housing unit with at least one housing unit (48),In order to allow the water supply system to be flushed by drinking water circulation in the pipeline containing the pump station without the water meter recording the quantity of water circulating at the closed pump station, it is provided that the drinking water supply module has a valve device (35) which is designed for this purpose, at an open junction, allow a current from a first junction (27) to a second junction (28) through a first junction (27) connecting the first junction (28) connecting the second junction (29) and through a first junction (27) connecting the second junction (28) connecting the second junction (30) block,where the second conduit is different from the first conduit and, in the case of a closed junction, to block a current from the first connection (27) to the second connection (28) through the first conduit (29) and through the second conduit (30).
