    2 port valve sticking open

    Hi, It appears the 2 port valve for the heating is sticking/stuck open. The heating is turned right down on the thermostat but when the hot water is on (separate 2 port valve) the radiators are also getting warm. I'm hoping it doesn't need to be a new valve...... Thanks in advance!
