A plumbing tool 10A includes an elongated hollow shaft 12A, 12A' and a resilient member 16 attached to the shaft adjacent a shaft end. The resilient member 16 extends radially outward and is sized to closely fit within a pipe (24, figs 2A-2E) inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. The shaft comprises a first section 12A to which the resilient member 16 is attached, and a second section 12A' which is joined at an angle to the first section. The resilient member 16 is preferably an annular disc. A valve (V, fig 2C) may then be passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the valve is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users. |
