I read it as where the pipe comes out of the screed. In my case, the
pipes come curve up and come out about 45° inside a cupboard and
continue curving to the vertical.
If so, I'd expect to chop the screed back until where the pipe was
horizontal, to avoid having the repair coupler under any strain on the
curve, best to have it buried in replacement screed after re-pressure
testing ...
