Any ideas about fixing this type of tap? It is dripping. When I opened it up it isn't what I'm used to.
There seem to be two very tight black washers part way up it (which look ok) but no sign of the usual big washer at the bottom (or a logical place for one to go).
I don't have another working one in order to know what it should look like and I don't know the name of this type of mechanism.
