the distance the user moves the handle 208 and the rate at which the handle 208 is moved may affect the amount of temporary vacuum formed typically the pull is completed in less than two seconds after the vacuum has moved the obstruction closer to the water line in the toilet bowl the obstruction may be repositioned or reshaped and the passing water may then naturally move the obstruction 220 with it and travel down the sewer line 120 if the obstruction 220 does not pass and the water level is low and safe the user may then actuate the flush handle 112 on the toilet to add water above the obstruction 220 which may naturally move the obstruction 220 towards the sewer line 120 if the clog is still not repositioned or sufficiently reshaped the user can separate the unclogging device 200 from the toilet bowl rim 124 enough to break the seal with the toilet bowl rim 124 in order to reset the bellows to the start position and try again the unclogging device 200 ideally never comes in contact with the water and waste in the inner toilet bowl area 116 and thus is more sanitary and efficient the bellows can be returned to the compressed state for storage under a sink or in a closet when the bottom surface 206 of the unclogging device 200 is placed in contact with the toilet bowl rim 124 and the diaphragm 202 is pulled.
