my husband claims that the water heater would still contain some water. If that is so, and it’s a 50 gallon tank and there’s 10 to 20 gallons left in the tank, if there should be a freeze (power failure plus generator failure), wouldn’t the water, as it begins to freeze, merely expand to fill the available space in the tank and not result in a disaster?
This has been driving me nuts!
TIA for any useful advice.

Hi Sue,
Besides just draining why don’t you simply blow out your lines with an air compressor? This would ensure everything gets drained. It’s very simple to do just hookup a small compressor (preferably oiless) to your blue well tank (well-x-troll), set your compressor for 60 psi, then just repeatedly open and close all faucets, toilet tanks, washing machine, etc, etc, in your home until nothing but air comes out. It’s really pretty simple and will ensure your lines are completely drained.
Don’t forget to run RV antifreeze through your washing machine to avoid serious problems in the spring!
Good luck!
Dan
