That’s a good start. Before you leave for an extended time in winter, follow these steps:
→Be sure the furnace or boiler has been cleaned and inspected.
→Turn heat down, but not off. Most thermostats will go to 55 to 60 degrees. Before setting it lower, check with the manual or ask the manufacturer.
→Empty refrigerators and freezers of foods that won’t last and leave them running. Or empty them completely, unplug them and prop them open.
→Disconnect hot and cold supply hoses to the washing machine and leave the valves open.
→Turn off and drain the water heater.
→Disconnect the water softener. It’s a good idea to do one final backwash before disconnecting, to make startup easier.
→Check appliance manuals for advice on shutting down or what to do when leaving for extended periods.
→If possible, make sure hoses connected to outdoor faucets are disconnected and fully drained.
→Pour nontoxic or RV antifreeze (not automotive antifreeze) into all traps and drains, including the dishwasher and showers. Use 2 cups in toilet bowls and tanks, and about 1 cup in other drains.
→Be sure windows, doors and fireplace dampers are closed and latched.
