Abstract: Fluid supply apparatus 104 is disclosed. The fluid supply apparatus 104 comprises a first conduit 106 to supply fluid to a fluid dispense head and a second conduit 108 to receive fluid from the fluid dispense head. The first conduit 106 and second conduit 108 may both supply print fluid to a print head in a printing or servicing configuration. The first conduit 106 and the second conduit 108 are coupled together via a closable third conduit 116. The closable third conduit 116 permits fluid flow between the first conduit 106 and the second conduit 108. The third conduit 116 comprises deformable walls movable towards each other to close the third conduit 116 to the passage of fluid between the first 106 and second conduit 108.
