Abstract A DEVICE FOR UNCLOGGING DRAINS OR THE LIKE WHICH INCLUDES AN ELONGATED, HOLLOW HANDLE PORTION AND AN INFLATABLE MEMBER CONNECTED TO A TERMINAL OF THE HANDLE PORTION. THE INFLATABLE MEMBER INCLUDES A FLEXIBLE STRIP WHICH CON STITUTES A FORMER WHICH MAY BE LONGITUDINALLY BENT TO SELECTIVELY ADJUST THE INFLATABLE MEMBER TO A RECTILINEAR OR CURVILINEAR SHAPE. A WATER CONDUIT IN COMMUNICATION WITH THE HOLLOW HANDLE PORTION EXTENDS LONGITUDINALLY THROUGH THE INFLATABLE MEMBER, AND TERMINATES IN A NOZZLE HAVING AN OUTLET ORIFICE. A SOURCE OF PNEUMATIC PRESSURE INFLATES THE INFLATABLE MEMBER TO SEAL THE DRAIN OPENING. A WATER SOURCE DIRECTS WATER THROUGH THE HANDLE PORTION, INFLATABLE MEMBER AND NOZZLE TO EXERT HYDRAULIC PRESSURE ON OBSTRUCTIONS IN THE DRAIN LINE.
