wonder if anyone has a good solution to my small problem.I have an outside toilet with a small sink, and the sink has a mixer tap.I only have a cold water feed and dont need a hot one, but of course the mixer tap has two feeds for hot and cold.When the tap is opened, if the tap is on cold setting (i.e. angled towards me when I lift it up) then all is fine...... but if it is turned away and then lifted up (whenever someone who isnt used to it!) then water from the cold feed 'drops' out of the hot feed inlet.So I need to blank off the hot water feed........ how would people suggest was best?
