Wall mount WC - leak at flush pipe entry to pan

[NickH]

You need to make sure that there is ABSOLUTELY NO grease or lubricant on the flush pipe or the inside of the bung. If you then fit the bung on the pipe it should stay put when you push the bung into the pan, which needs plenty of grease in and around the hole.
