I don't have any water coming from my well. It is way below freezing outside, but I have a heat tape on my well head that has always worked and feels warm. I added a heat lamp late this afternoon. I have the kitchen faucet wide open and still no water. I noticed that the gauge for the pressure tank is reading zero. Is this because the well or lines leading to the house are still frozen, or could it be that the pressure tank has a broken bladder and this is why I don't have any water?
