The tap on my apartment balcony is dripping even though it is tightly closed. I think I need to change the washer but I don't know how to pull apart the tap. When I see videos online, the spindle can be removed. However with this tap, the spindle seems to be joined to the tap body. There is also a chunky part near the spout but don't know what this does. Does anyone know how to open and fix this type of tap?
