A. Turn OFF the power or gas to the water heater and the water to the home (public water at meter base, private well water at pump).
B. Open the lowest cottage drain points (probably outside water spigots) and open all faucets and the T&P valve at the top of the water heater (for air) to drain down the lines. Attach a hose to the bottom drain valve of the water heater to drain it. Don't forget to turn the washing machine on briefly to relieve water pressure, turn off both hot and cold washer supply line faucet handles, and disconnect both the hot and cold supply line hoses (drain those into a bucket). If you have a dishwasher, turn it on for a minute for the same purpose.
C. If you have a surface water well pump, remove the small 1/4" plug on the bottom of the pump head and drain the pump. Drain any well or pump lines at the lowest point possible.
D. Pour home/RV anti-freeze (NOT the very poisonous auto anti-freeze) into all sink, tub and shower traps and toilet bowls and tanks...wherever there is standing drain water. (Flush the toilets after the water is off and before pouring in the anti-freeze, of course.)
If you have a portable air compressor, you might want to blow the excess water out of the supply lines with it just for insurance. If a line has a dip in it it that will hold water, it might freeze.
That should do it.
Good luck!
