As Jim says simple empty all the tanks including the hot water tank before adding the anti freeze. Never had any issues with using the approach I mentioned (dump out all your tanks, dump some anti freeze into the fresh tank and run the pump and open the facets to fill the lines). Also not an issues if you do happen to get some into the hot water tank! The hot water tank really does need due to its design a good cleaning out each spring regardless - failure to do so will result in a build up of crud in the bottom of it that will not only shorten its life but start to smell real bad if left in there and you use the tank or you leave the tank full of bad water in hot weather for a good stretch of time. The good thing about using the approach I mention is that the anti freeze will also go through the water pump - not so with other approaches unless you disconnect the water lines from the pump to allow it to fully drain. I know way to many folks who have had to replace water pumps each spring as they did not drain them or run anti freeze through them.
Every spring I do a good sanitizing of the whole water system. Not just because of anti freeze but because I do a lot of dry camping
and have been known to get some pretty questionable water while on the road. Never have had a problem with water smelling like anti freeze or other concerns some have mentioned. Even if you did not clean it out of the tanks they can still be used it not dangerous just may have a funny smell to the water! The anti freeze is made for use in RV's and home plumbing. Heck being a Canadian I am sure you are aware the anti freeze in used in the plumbing of thousands and thousands of summer cottage all over the country!
I am sure it would be a big news story every spring if people were being badly impacted due to having used anti freeze in their plumbing systems.
