The flow path comprises a boiler chamber detachable from the sand filter for the water recirculation and a base compartment provided below the sand filter for impacting the filter cartridge, whose outlet pipe flows into the boiler chamber. A non-return valve opening itself into the base compartment is provided in a section of a bulkhead wall present between the sand filter and boiler chamber and separating the boiler chamber from the base compartment. The outlet pipe of the filter cartridge is closed with a non-return valve opening into the boiler chamber.
