<p>A percolation filtering device comprises a divider element which divides the device into a top tank and a bottom tank, communicating with each other through a channel defined in the divider element which forms a seat for receiving a filtering cartridge. A valve passage is defined in the divider element, suitable for housing a flow shut-off valve to allow/prevent the passage of liquid between the tanks. The passage is arranged, when in use, downstream of the filtering cartridge and comprises an extension, secured to the passage and arranged upstream of a valve member of the shut-off valve.</p> |
