ABSTRACT:
The present invention is a method for preventing fluid from reaching a portion of a pipe to permit soldering of a threaded adaptor or valve onto the pipe. The method includes the first step of inserting a hollow member through the adaptor or valve. Next, there is the step of inserting the hollow member with an expansion sleeve into the pipe. Then, there is the step of expanding the expansion sleeve such that the expansion sleeve forms a seal in the pipe and fluid from a fluid source upstream of the sleeve is diverted through the hollow member past the portion of the pipe and soldering the threaded adaptor or valve onto the portion of the pipe. The present invention is also a method for preventing water from reaching a portion of a pipe to permit soldering of a threaded adaptor or valve onto the pipe. The method includes the first step of inserting a hollow member through the threaded adaptor or valve. Next, there is the step of inserting the hollow member with an expansion sleeve into the pipe. Then, there is the step of expanding the expansion sleeve such that the expansion sleeve forms a seal in the pipe and water is diverted through the hollow member past the portion of the pipe and soldering said threaded adaptor or valve onto the portion of the pipe.
