Miniflex vs Flexcon

[Stringman_uk]

Hi all
I am getting a leak between my waste pipes.
I have worked out that the final waste (that goes through the outer brick wall is not perfectly in lined with the rest of the pipe run, so it leaks from the join at a T piece.
I was thinking of inserting a flexible pipe in the run so that the pipes align.
I wondered what the difference between the McAlpine Flexcon and MiniFlex range are?
And which, if any, is better.
Thanks in advance

Cant quite visualise what you mean but the only way to do it properly is reset the pipe run so it all has a fall on it and use glued connections. I wouldn't use flexi couplers on any waste run, just to correct something that should be sorted out
