Preferably, the liquid dispenser includes a main housing having a dispensing location at which liquid from a liquid storage container is dispensed and a storage location for storing a liquid storage container. Preferably, the liquid dispenser includes a removable liquid transport assembly removable from the main housing having a substantially rigid liquid manifold, a valve assembly, a riser tube, a reservoir, a reservoir dip tube, a pump head, a pinch tube and a dispensing nozzle that are removable as a single unit from the main housing. Preferably, the liquid dispenser includes a single self-priming pump. Preferably, the valve assembly includes a non-return valve and a pressure relief valve that act in concert to control the flow of liquid between the liquid storage container and the reservoir.
