Hi, can anyone help please, I have just noticed (not been in the house very long) that whenever the shower is on, if any other hot water tap is turned on in the house, the water from the shower stops completely. I knew that combis did this to an extent and reduced the flow but not to stop the flow completely, especially when the shower is right next to the combi and the tap that's turned on after is in the kitchen downstairs.
Could there be a problem somewhere with the combi, the shower or the mains water pressure is there any way of checking what the water pressure into the house is and/or checking anything on the boiler for pressure/diverters etc
For info I have a Mira excel shower and a Vaillant 24KW combi VCWGB
