My top up light seems to be coming on more than usual. i had to turn the valve twice today. is this anything to do with the cold weather?We have recently built an Extension at the back of our house,a lounge, a toilet/shower room,and a utility room.The lounge and toilet have radiators in them. All ahs been well till a few days ago. Is a leaky pipe under the floor a possibility?the boiler is a voikera.
