When we winterize a home, we remove the meter and use air pressure in all of the water pipes to empty the lines. We then drain the water heater and shut off the burner. We empty the toilets and tanks and fill all the traps in the home with RV antifreeze. If there is a dishwasher, we flush out the supply with air. Even with everything shut off, you have to supply heat to the meter area to keep the inlet water supply from freezing. This can be done with a 100-watt light bulb.
