A hose reel assembly comprises a drum (3/4) borne on a cantilevered support tube (1). A rotary joint assembly to direct water from a feed pipe (12) to the hose connector (19) of the drum comprises a fixed conduit member (9) mounted within the support tube and a rotatable conduit member (14) sealingly journalled to the fixed member. An inlet port (10) of the fixed conduit member receives the feed pipe (12) and an outlet spigot (18) of the rotatable conduit member is connected to the hose connector (19) by an external sleeve (20). If it is required to have access to the joint assembly (9/14) for maintenance purposes it can be removed from the reel as a complete unit by disconnecting the feed pipe (1), removing an access cover (8) at the accessible end of the drum hub, disconnecting the outlet spigot (18) from the hose connector (19) and withdrawing the joint assembly through the open end of the hub. |
