Water Line Treatment while away

I’d drain them along with the water tank, pull any slides in, make everything is all locked up and go. Perhaps keep a roof vent slightly open to help dissipate heat build up.

Drain everything then sanitize with bleach when you return.

x2 drain blow out and bleach when you return.

Unhook from anything with pressure. Wouldn't worry about any water in lines during the time you are gone. Ours sit each winter in AZ. Come spring, we run fresh water through it, dump fresh water tank and refill, and away we go. Make sure you've cleaned out the fridge and leave the fridge doors open. Leave roof vents cracked (assuming you have covers for them.). Through disconnect switch for batteries. Close blinds, away you go.

x3 and 24 hour bleach soak too.

Same as winterizing. So far this year, you can't tell what the weather will be

X3

There is simply no way you can avoid "things" growing in the still water inside the water heater and plumbing, whether drained or left full. So your best bet is to minimize the growth media by blowing 'em out as though winterizing, and when you get back, sanitize the system, either with bleach or hydrogen peroxide.

Thanks all.

Unless you plan to use very strong hydrogen peroxide (not off the shelf stuff), stick to bleach.
