Floor-watering systems for feeding water to animals such as poultry have at least one vent (22). This vent (22) has to be closed in order to flush the floor-watering system (10), so that a flushing pressure can build up which is higher than the watering pressure. In prior art floor-watering systems (10), the closure and opening of the vents (22) requires a substantial amount of time and effort. To provide a remedy in this respect, a water supply line (17) of the floor-watering system (10) is associated with at least one shut-off member (27) or the like which is actuable by a movement of the vent (22). As a result, the readily accessible and easily actuable vent (22) forms an actuating member for closing the shut-off member (27) or the like in a simple fashion. Consequently, no tools are required for the closure and opening of the vent (22).
