I've been googling around to find guidance on the best way to flush appliance lines and pipes and different jurisdictions have had slightly varying guidance.

1.) Most importantly, the pipes in general. Cold water on for at least 5 minutes? I read somewhere to start at your bottom floor and work up and to include exterior faucets. Special considerations for hot water recirculators?

2.) Flush water line to fridge. But for how long/how much? (Manual doesn't say how much is stored in our fridge.) Our water filter indicates 1.5 gallons/3 minutes worth of flushing when you put in a new one. Is that a good way to estimate for these purposes? Also, you should get a new filter.

3.) Ice Cubes: Empty 3x, wipe out caddy with disinfectant.

4.) Dishwasher: Do we just run it once? Yes, I know you can run with sanitize on even with a boil notice on, but I'm a paranoid type that wants to be safe.

Anything else we need to be thinking about with this situation? I don't know how I have lived here for over 15 years and never had to deal with this before.
