Ok this is my first time having to dewinterize my x17z. I am at a total loss and afraid to do anything! Anyone have step by step directions or want to post a video to help? I have searched youtube for something and can't find anything. We have a trip coming up and I wanted to get this done this weekend so I am all set to go. Please help me!!!

Dewinterizing is much easier that winterizing. Most people dewinterize on their first trip of the season at a CG with full hookups but you can do it anywhere if you have can dump your grey tank soon afterward.

Start by hooking up to a city water connection (you can also use the FW tank and pump but it's easier using the cit water connection). Starting at the faucet closest to the water inlet (kitchen for me), open the faucet and let the water run until the pink water turns clear. I usually start with the hot side then do the cold side but it doesn't matter...you are just using water pressure to displace the antifreeze in the lines.
Move to the next faucet, shower head, toilet toilet or whatever has a valve next and repeat the process until the water runs clear at each. I go an extra step and open the low point drains and flush them too but I doubt some people go that far.

Once you have purged all the water points, shut the city water off and don't forget to open your bypass valves to the hot water heater. You can install the hot water heat drain plug and fill it if you are ready to use it or you can skip it and wait until you are ready to camp.

Dewinterizing shouldn't take long ang you might use several gallons of water that will need to be dumped at some point. It's an easy process...don't sweat it!

and then

Sanitize the fresh water tank. This needs done on a new RV, and then periodically. I sanitize ours before each season, and we're good for the summer. This is done by adding a small amount of bleach to a tankful of clean, fresh water. Let set for a few hours, drain and refill with freshbwater to rinse. I follow that with a vinegar and tank of water flush, leaving that in for three days. Refill and rinse.
I don't have the ratios at hand but somebody will provide, or I'll update later.
Good to check spare tire, lug nuts, tire pressure and smoke alarm at this time.

ohh this is great news and makes it sound so much easier than I am picturing. If you can get the ratios I would greatly appreciate it. what does the vinegar rinse do??? how does any of this effect the hot water tank??

Did you winterize it or did someone else do that?
I'm asking because of the water heater:
If the lines were blown out with air, you need to be sure the water heater is FULL of water before using it. You also need to be sure the water heater valves are not set to 'bypass.'

If one of the other posters mentioned this... sorry for the duplication.

I winterized it with some help from my bother so no air was used to blow out the hot water heater....If I remember correctly we drained it?

Then to get the antifreeze out of your lines.....do not open the bypass to your hot water tank until you get rid of the antifreeze out of your lines. You do not want to run antifreeze through your hot water heater.

Hook up to water through your city water line. Open up each tap and run until the pink goes away. Remember your outdoor shower as well. Once that is done,you are going to want to run bleach through your lines....mix some bleach into a jug and use your winterizing line to run bleach and water in to the lines the same way you did when winterizing. Let that sit for a couple of hours and then hook up to the city water again and run the water taps again until you no longer smell bleach. Then turn on the bypass to the water heater after the water is running clean.

If you are sanitizing your fresh water tank the ratio of bleach to water is 1/4 cup per ten gallons. You will need to fill your fresh water tank and let sit for 4 hours or so. Do this after getting rid of the antifreeze in your lines and you can skip the step of running bleach through your lines as you will be doing so when sanitizing the fresh water tank.

Amazing information! I feel so much better about doing this. On a side note what do you do if when dewinterizing it you opened the bypass and got antifreeze into the hot water tank by mistake. My brother did that by mistake and I would love to tell him how to fix that issue!

Drain. Open service panel. At the bottom you will find a white plastic threaded plug. Drain, plug, fill, drain.

When I winterized, I bypass the hot water tank and drain it, then fill the house
