A cleaning connector (22) for a cleaning bottle (11) (Fig 2) for a liquid dispense system (10), has a dip tube (25) and a liquid-level dependent valve (27) at its lower end which prevents fluid flow to the dip tube when liquid level falls to a predetermined value. The system uses gas under pressure in a cylinder (17) to force a liquid, particularly beer, from a keg (15) to a tap (13). For cleaning, the coupling (20) is disconnected from the keg and mounted on the cleaning bottle (11) so that the pressurised gas can be used to force a washing liquid (24) into the pipe system. The valve (27) ensures that there is no loss or wastage of the pressurised gas if the washing liquid level falls to the level of the dip tube inlet. <IMAGE> |
