de winter
We just did that a couple weeks ago. I hooked up to the campground water , then turned all faucets on till no more pink. Then I made sure the valves were turned for the hot water bypass.Then the hot water tank filled. I then ran everything for a few minutes,shower, sinks, outside shower, flushed toilet. ect. Then I believe I turned the city water off and ran my pump and did the the same routine. If I did something backwards hopefully some onew will corect.
Ron Ps I think I filled my storage tank a bit first before I hooked to the city water connection. I didnt winterize that because I drained it for the season.
