Open the uppermost valve in the house, such as a showerhead on the top
floor. Open the lowest valve valve. Most of the water should drain.
Try to keep the house above freezing. Be extra safe with kerosene.

The lowest valve is usually the water heater drain, or an expansion tank
drain if you have a well.


And don't forget, if you have a garden faucet on the outside of your
house, you may want to close the valve on the inside and open the outside
faucet. Water freezing inside the faucet body can cause the faucet body
to crack open. Up north, common practice every fall where expected temp
at least one or two days is below zero F.
