ABSTRACT:
A plumbing tool permits a drain body to be held in a drain opening of a bathtub from behind a drain end of the bathtub. The plumbing too has a head that can be engaged to the drain body and a handle that can be positioned so that an end of the handle projects through an overflow opening of the bathtub. The tool can prevent rotation and lifting of the drain body.
