Mira 722 Wall mounted control valve only giving HW even when turned to CW - any suggestions as to where I start--repair kit? I know it is supposedly a low pressure valve and we have just had a new combi fitted where no CH boiler fitted previously. Could that be a cause and if so is there anything I can do?
The valve is designed for low pressure hot water but now it is higher so there is incompatible flow rates, you would have to ring mira to see if there's a kit to alter it otherwise it means fitting one specifically for combi's
