My goal is to replace the washer in this tap.
I have been unable to do this because I need to be sure how to unscrew the tap and/or why it cannot be unscrewed.
There is no nut at the front or screw on the side. There are 2 notches on the disk at the back.

I tried a tool with 2 prongs but I could not get enough force to loosen it. It was pretty cheap tool though and the prongs ended up breaking off:
Is there a better tool or method to loosen it?
