If you drain all lines and the water heater, Then blow them out with compressed air.. I like to do that step like 10 times pausing between blows.. You need NEVER put antifreeze in the lines.. Just toilets, and drain traps.
And you can do those any time
Advantage to dry method:
If you put antifreeze in the lines.. You have to get rid of it and flush it all out come next season
If you only use it in toilets and traps... Well,,,, those Flush naturally don't you know. You will flush 'em out when you sanitize next season but no special effort needed and even if you don't get it all out.. Who cares.
Home was where I park it. but alas the.
