I've just had a new mixer tap fitted on kitchen sink and now our combi boiler is being triggered even when the tap is set to draw cold water. This should only happen when the tap is drawing from hot. It doesn't happen when the tap is only turned half on, only when it's on full.
This never happened before we changed the tap but previous tap wasn't a mixer. Could the tap have been fitted wrong (by professional plumber) or could it be just a small adjustment is required somewhere?
