I have an Aqualisa shower that works off a mixer tap on the bath. Not sure what model it is but it could be ten years old. I've looked on various websites and haven't found anything that matches the look of them, although it is similar to the Aquamixa in design, but looks older and chunkier.
Anyway, the problem is that there doesn't seem to be any cold water coming out of the shower head, just the hot stuff. There's a rotating bar behind the tap head for the shower that can be adjusted clockwise or anti-clockwise (temp. control) which doesn't make any difference (to the temp. or the flow). The (separate) taps for the bath work fine, both hot and cold.
Any help is obviously much appreciated.
