Had a mixer shower installed a few months ago, its been fine for like 6 months but few weeks ago its got so you have to turn it up really hot for it even to be warm, or it will be hot then go cold, but the taps come out really hot. and now even with it on maximum its hardly warm. i tried reducing the flow on the cold intake on a isolation valve but this just drops the pressure. i also tried adjusting the temperature thing inside the mixer button but this didnt do much either. any ideas? its an altair triton thermostatic mixer, and its a combi boiler.
