some good tips,,,,,, I have a separate cut hose about 3ft long I use to fill the tank,,, also use a funnel with a flexible tube to pour bleach into tank from water sprout, I turn on all the water to get some in each line sinks, shower, outside shower, want to keep those hoses/pipes clean, sanitized also,,, leave it overnight, ready to go,,,, I do this twice,, we are spring/ fall travelers and usually have up to 4 months between trips.
I use our water for cooking, cleaning, showers, ice, coffee etc,,,,, how ever we do carry bottled drinking water
