Pics below show the waste pipe from a kitchen sink leading into the vertical soil stack. The problem is that the 90 degree elbow keeps popping off the pipe where it immediately exits the wall. The problem is due to the whole abomination being 'sprung' into place so it's constantly wanting to spring out of place.
So the question is how best to fix this. At the moment it's a combination of a 90 degree elbow and 45 degree elbow. It wouldn't be easy to adjust the position of the 'inlet' (for want of a better word) on the soilstack where it's bossed in, and obviously the part that exits the wall is staying where it is, so what can be done to sort it out? I've seen flexible waste pipes but these seem to be for internal use only.
