Winterizing

[Farmer]

I have a 04 Holiday Rambler Presidential 36SKQ 5th wheel. I have 3 water connections on the outside. They are City Water, Winterize and Black Tank. Depending on which one I am using. There are water valves that have to be turned a certain direction.

When I winterize my 5th wheel (first time for me) this year. How can I winterize it if the water pump doesn't work? I hiave seen a video and read that a RV can be winterized by pumping antifreeze into the City Water connection.

Is this correct? If so would I have to still turn the water valves for winterizing? I assume I would. I wouldn't want the antifreeze to go into the water heater or drain from the low point drains?

If you don't put it in winterize mode it will put antifreeze in the water heater as that is the normal path for city hookup. IF you pull the drain for the water heater and let some anti freeze come out, no biggie. But things down stream from the water heater on the hot side may not get any antifreeze. Maybe the water heater is shut off in winterize mode and bypassed? But then it would have to be drained completely by the low point drain or pulling a plug.
I have found there are an incredible amount of different setups on factory systems to winterize. It should be so simple. A young man just joined our business from Alaska and they used air to winterize and guaranteed the results. Up to 60 units a day by one man. I personally like antifreeze in mine.
