Claim 6:
7. A method for replacing a valve in a pipe, comprising:
placing a housing (9) in fluid-tight engagement with the pipe on a right side and left side of the valve;
cutting the pipe on the right side and left side of the valve, thereby creating a right side opening and a left side opening in the pipe;
removing the valve through the housing;
advancing the replacement valve assembly (40) of claim 1 into the housing, wherein a cut-covering assembly is disposed within each pipe end (21) of the replacement valve assembly (40);
placing the pipe ends (21) of the valve assembly (40) into alignment with the right side opening and the left side opening of the pipe (35); and
rotating a valve (24) from the first position to the second position, thereby urging the right side end of the right side cut-covering assembly (621) out of the right side cylinder (223), and simultaneously urging the left side end of the left side cut-covering assembly (622) out of the left side cylinder (225), thereby pushing the cut-covering assemblies (62) outwardly through the pipe ends (21) and into the cut ends of the pipe (35) and placing the valve assembly (40) into fluid-tight engagement with the cut ends of the pipe (35).
