Dewinterizing new fifth wheel

[HappilyLost]

Good evening. I went to a fifth wheel this year from a travel trailer and it’s a very different setup as far as wet bay. In the travel trailer I just hooked up a hand pump to the city water intake, bypassed water heater, and pumped antifreeze to all outlets. Then drained tanks.


Now I have a hose that’s for winterizing (how do I use that) and two low drain point spots. My question is how do I winterize this fifth wheel the way it should be? Does the water pump pull the antifreeze in from that hose? Do I open those drain points to get any remaining water our first? Any and all info appreciated and If you need more info please ask. Thanks

Remove cap on wet bay board. Fasten hose end and put the end in the anti freeze. Switch valves to the winterize position. Turn off all faucets. Turn water pump on. Once it reaches pressure and shuts off, open the furthest faucet till anti freeze comes out then turn off faucet. Continue too next furthest faucet till all are done. Be sure water heater is by passed and always have the hose supplied with anti freeze. I then open the two low point drains to make sure all the water is evacuated.
