This is, I hope, quite a simple query. All I want to do is remove a white pipe from the drainage pipe of a dishwasher (see attached picture to see what I am on about).
The white pipe isn't screwed-in to the drainage pipe, so unscrewing it doesn't work. I have also tried using my - above average - levels of strength to separate the pipes, also to no avail.
The only thing I can think of is to cut the drainage pipe off at the end, just below the rubber seal, but I'm pretty certain that will lead to leaks when I plumb the drainage pipe in and use the dishwasher.
Can anyone help? I would really appreciate it.
