Filing Nails at Night

I use a cup for netilat yadayim whose handle is held by four screws, and after about ten uses the handle becomes loose. I filled the cup completely with water at night, and by morning it was only half full because the water had leaked out. Since it is leaking, is the cup still kosher for netilat yadayim?
