leaking toilet outlet pipe

[mondial]

My toilet has a horizontal pipe, straight out of the back of the pan and through the wall. There is a joint in this pipe where the outlet of the pan meets the straight pipe and it is leaking quite badly.
What should I use to seal this and how do I apply it?

Might pay you to replace with one of THESE or an offset one.

Thank you for the suggestion but that will entail removing the toilet pan from the floor, also possibly breaking the soil pipe when I try to remove the leaking Joint. Is it not possible to just seal the existing joint? With What? And, how?

You could try silicone for a bodge.

I would do it properly and have done with it. I would think it is leaking beacause it is not seated properly i.e not pushed home or is at an angle.

Get a new connecter mate.
