Hi everyone, with a lot of help from this forum have got my shower enclosure all finished. I have one more problem which I hope someone can help me with. I have a thermostatic mixer shower running of my combi. It has a rain shower head which works perfectly but when I switch to my hand shower head the water goes cold. When I take the shower head off the water gets hot, shower head back on and it goes cold. This is a new mixer shower so should work fine. By the way the shower head has 3 settings on it, could the shower head be faulty or will there be some settings inside it.
