<p>A device (D) for unplugging drains (12) comprises an elongated body (16) defining therein a longitudinal bore (18) and including a pair of opposed end sections (30,32) each adapted to threadably receive a standard hose (4,34) and provided with two different configurations of L-shaped lugs (36,38) for connection to various drain pipe strainers (10). The device (D) defines central outside threaded sections (20) with an enlarged nut (22) being engaged thereon. Between the central threaded sections (20) and both the end sections (30,32) are defined smooth annular neck sections (24,26) adapted to receive a resilient annular member (28) for sealing the mouth (14) of the drain pipe (12) when the device (D) is mounted to the strainer (10) thereof. Water supplied by the hose (H) through the bore (18) of the device (D) provides water pressure in the drain pipe (12) for unclogging the same. Various adapters (A,58) which can be fitted to the end sections (30,32) of the device (D) are contemplated for allowing the device (D) to be used with further drain configurations (14a) and also with compressed air (60). <IMAGE></p> |
