Just a little background info, I have very little knowledge in this area so forgive the possible stupid question.
I have a Lecico sink in my bathroom and the pop up plug has failed. I have tried to replace this with no real success. The issue is the "screw" part that joins with the actual plug. From what I have read, M16 seems to be the only size but it's too small. The opening where the thread needs to contact is a 20mm. Would anyone have any idea if there is a pop up plug in existence that would fit this? And if so what size?
I can't remove the actual waste pipe due to the sink being bolted to the wall and sealed which rests on the pedestal, which, conveniently, has a lip to prevent you from moving it out.
Many thanks in advance if anyone can help me.
