Re: Water filters built into rv
We also have been drinking the water out of the tanks for years. I usually refill with fresh just prior to leaving, and then as needed along the way. I've never had a problem with RV water.
As it happens, my new Roadtrek has an Instahot dispenser (actually both hot and cold) with a filter in its supply line, for whatever that is worth.
Sometimes in the back yard I drink from the hose, too, and did for years as kids. Still alive.
