Abstract: An implement for dislodging lumps of matter clogging a drainpipe comprises a long handle with a resilient cup attached to its lower end, the cup having several slits that extend from its rim down to form a plurality of petal-shaped leaves which yield inward when the cup is thrust from above into the pipe but which hug the pipe wall on being pulled up. On being vertically reciprocated inside the drainpipe, the cup thus acts as a pump drawing up water and dissolving the obstruction.
