I developed this list when shutting down the cabin in Maine.
Thanks for spending time on the computer (wtriing) so others don't have to.
 
;To prevent pipes from freezing and critters from entering a house, follow these steps:
#Remove exterior screens.
##Replace with storm windows if available.
#Lock every window and door.
#Turn off water heater before turning off water.
##For electric heaters, turn off circuit breaker.
##For gas, follow specific instructions.
#Turn off circuit breakers to everything but important lights and security system.
##If there's a breaker to a water pump, turn it off.
##If you turn off the refrigerator, leave the door open so oxygen gets in and mold doesn't grow. But beware of mice, their feces is not something you want in a refrigerator.
#Turn off water. There should be a valve where the water supply enters your house, usually just inside the wall penetration.
#Drain water pipes and water heater (after water heater is turned off):
##Attach hose to lowest spigot, and the one on the bottom of the water heater. Lead hose outside or to a drain lower than everything else.
##Shut off water supply to house.
##Open drain valve attached to hose.
##Open all faucets, valves. If you have a single knob for both hot and cold, as in a shower mixing valve or kitchen faucet, set it to the middle position so both hot and cold drain.
##Flush all toilets, keeping handle held down while pipes drain.
##Wait two minutes or until there's no more flow.
##Close all but one valve, leaving one slightly open over a sink to allow air and trace water to expand and contract. Since it's a sink, if water does come through, it'll drain.
#Pour antifreeze in all drain and toilet traps to keep sewer gases trapped.
#Turn heating system thermostat to low or off, depending on your decision.
 
===Re-opening a winterized house===
#Air out the house immediately, in case sewer gases built up.
#Open a faucet or two, especially high in your house, to help air escape while you re-fill the pipes. The less air, the less the system will bang and spurt later.
#Turn on the circuit for the water pump.
#Turn on cold water supply.
#Turn on the water supply to the water heater.
##Check to see if there are any leaky pipes. If so, there may have been ice in them which may have burst the pipes. Consider PEX piping.
##Close the faucets you used to release the air.
#Open and close all faucets and flush all toilets to release the air from all the branches of the pipes.
#Only when the entire system is flushed with water turn on the water heater.
#Turn on the house-heating system as needed.
