I am currently trying to change my bathroom sink drain (uk). I have very little room to get in behind the basin leg to remove the drains back nut. I have tried to remove the back nut with knipex water pump pliers, but the plier handles hit the wall so I can't get the back nut undone. I then tried a stubby wide jaw adjustable spanner, but again had no room to turn the spanner to undo the nut. I bought a basin backnut box spanner which can remove 46mm and 50mm nuts. After trying this, it seems the 50mm end is too small for the backnut. Has anyone any idea what size the backnut could be? It says online that most basin backnuts are 1 1/4, so I've no idea why this one is bigger than 50mm. Or if you have any other ideas on how to remove the drain? Thank you. Any advice is much appreciated.
