De-winterize
In order to de-winterize, I filled the fresh water tank, turned on the water pump (which was very noisy) and it ran for some time and I did not get any water pressure. I then hooked up the city water supply and ran water through all the outlet to eliminate the anti-freeze. I kept the hot water heater valves closed to avoid anti-freeze going through there. I don't see any switch to change from city to tank, so I am not sure why the water pump did not work off the water tank. I have a 2021 288 ISL. Any advice would be appreciated.
