vier digital mixer-high pressure/combi shower

Even when off the cold water is coming through and out of shower head isolated cold supply to digital box in loft space
Asked 5 years ago by John
The mixing valve or the pcb controlling it maybe faulty. If when you switch the power off to the controller the water stops could indicate that it is the pcb at fault.
