The water temperature from the Heritage exposed valve shower started to fluctuate some weeks ago. At first I thought it was the boiler but that checked out fine. The only way I can get the thing to fluctuate between hot and warm rather than warm and cold is to decrease the water cold water pressure into the valve. I'm a little embarrassed that I can't sort this as there doesn't seem to be much to the valve......stumped! Any ideas or suggestions would be much appreciated.
Thanks
