Hi -- I am unable to locate the screw which will reveal the inner workings of the tap. ( I want to renew the washer ). It is a fairly modern mixer tap. ( 2 seperate taps and 1 spout ) I don't believe it is hidden under the red spot as it is very small and I don't think it will come off anyway. There is a " gold " decorative band about two thirds of the way up the tap and there is a possibility that the top third of the tap is screw / unscrew cap which would reveal the holding screw / inner workings. I have tried moderate force and am unable to remove this top third ( if indeed it moves at all ) . Hope there is enough information there for you. Any ideas anyone please ?
