A sprinkler arrangement comprises a sprinkler head connected via a first valve to one end of a length of connection pipework adapted for attachment to a main pipework system containing fire extinguishant. A second valve is arranged at the other end of the connection pipework and comprises an inert plug which is maintained in a valve closed position by a strut which contacts the first valve. On opening of the first valve, for example when a predetermined temperature is reached, the strut is caused to move and thereby permit movement of the inert plugs to allow a flow of extinguishant into and through the connection pipework to the sprinkler head when the arrangement is attached to the main pipework system.
