Abstract
A plumbing tool and its method of use are disclosed wherein the plumbing tool includes a tube for insertion into a pipe beyond an area of such pipe that is to be soldered, such tube having an inflatable balloon structure at one end thereof. After the tube is inserted in the pipe and the balloon structure is positioned at the location where fluid stoppage is desired, the balloon structure is inflated to allow for soldering operations to be completed. A water bypass can be disposed within such tube for directing any fluid flow to the exterior of the pipe.
