    squealing noise in bathroom mix tap and how to open up the tap

    The bathroom mix tap has developed a loud squealing noise. We suspect it's the problem with the washer by checking the related threads in this forum. But we need to open up the tap. Anyone knows how to open up the tap (the image attached), for which we don't have a clue yet. Many thanks.
