The 'Pro' answer would be to use a pipe freezer kit .... these will hold

Possibly. Only there was a problem with taking that approach. The tee
was about centrally placed in the pipework - and on one side the pipe
disappeared through a hole in the brickwork, without there being any
access to the remote side. And the distance between the tee and the
wall would have made the freeze too close to the flamethrower.
