    I would ask the same thing about ANY mixing faucets that have been replaced or repaired. This sounds like a cross connection. Regards, Tom

    No changes. Just happened yesterday. I have switched off the emersion heater and run the taps to empty the hot (steaming!) water from the cold water tank in the loft. Now the water is cold. Tried turning the emersion back on and it went pop - like a lightbulb sound. So switched it off and awaiting plumber.
