Smile Winterizing the Classic!

Folks, We are soon approaching that time of year. I was reading over the threads on winterizing in that forum and found some really good ones on that subject matter. However, I didn't find any particularly on the 345. Would it be basically the same for the classics as in the travel trailers?
This will be my first attempt at Winterizing. I have experience with Winterizing an inground pool and know a little about that and have read over the posts on this subject matter. I was wondering if any of you with experience on this issue would like to advise on this. It would be truely awesome if someone could take some pics on the process. Particulary on where the drain on the water tank is. And the drain valves at the rear of the coach. If nobody is willing to jump on this, than I may try to take this project on myself. Thanks in advance!

Winterizing the 345 is just like anything else. If you have the normal rear queen floor plan, there are three drain valves in the area of the pump. There is a section of wood that pulls up in the street side rear corner under the matress for access. Drain those first, and close.
Then use some compressed air and blow out the shore water hose.
I have the waterheater bypass, so I just go to bypass, and drain the hot tank.
I then take the intake hose loose from the fresh tank, and put it in a jug of RV antifreeze. My wife runs the pump, and we pump the stuff so it comes out of each faucet, and the toilet. I think it usually takes about 3-4 gallons.
I then pour some down each drain, and the toilet. This protects the drain traps.
No one told me in the beginning that the antifreeze would screw up the plastic of the bathroom sink and shower floor. So be sure to wipe any up that is left on these surfaces.
Hope this helps, Rob

Thanks Rob, I will look to see if mine has the bypass on the Water heater installed by the PO. If not I would like to install one. Did you plumb yours in yourself? I have already got 7 gallons of the antifreeze onhand. The intake hose from the fresh tank that you are referring to is located underneath the coach, right? I have read some mixed comments on whether or not to put the antifreeze in the fresh tank. Is this advisable? Also, when do you usually winterize your coach? Here in southeastern Kentucky we have already dropped down into the low 30's this week. I sure don't want to mess up and let my pipes burst or mess up my water heater.

I just wanted to add that there is a water filter in my closet that I need to winterize and the hot water dispenser that is located at the kitchen sink. Then, there is a hand sprayer at the kitchen sink and one that is located in the bathroom behind the commode.

I remove my water filters and hand sprayers, an easy job. Next is to carefully check all closets and cabinets for anything which can freeze. A can of soda or cleaning supplies will be a mess come next spring. We use out motor home all winter so I do not fill the lines with anti-freeze but do have a tool I made to blow the water lines clear of water with my air compressor. I also have a by-pass for the water heater and will drain it and not use it during the winter time. Make sure you drain yours.

JaG,

You can buy a screw-in plug that replaces the fresh water hose. It has a schrader-like valve without the core. You hook up your compressor with a tire chuck. I would get one that will attach to the valve so you don't have to hold it on. Make sure your pressure is dialed down. Then go around and open all spigots, shower heads, etc. Don't forget to open up the ice maker as well if you have one. Take out the water purifier filter(s). Open up the water heater drain (if you don't have a bypass) and let it blow out air/water for a while.

Any RV store should have one of the plugs.

Follow that up with the RV antifreeze in the traps.

Steve

Chap, so what you are saying is that I could still use my MoHo this winter, but would have to blow out the water lines after each use, right? What about getting all the water out of the tanks? Are they blowed out too? Sorry for sounding so ignorant, but that is what I am due to lack of experience.

For the fresh tank, I just pump everything that will pump out. What remains has never been a problem. The black and gray, just dump everything that will come out.
The hose that comes from the fresh tank to the pump is located in the bay where the pump is. Under the bed, on the street side rear corner. There is just a hose clamp that holds the hose onto the fresh tank nipple.
Each year we have winterized at a different time. I just let the weather make the call. We like to use the coach as long as possible. If the temperature starts getting below 30, then it is time.
We go to Florida in late January & February. I allways have to rewinterize on the way home the last morning in Atlanta.
Hope this helps, Rob

What we do is fill the tank at home since water is hard to find on the road and a full tank is less likely to freeze than a partial tank. We do all of our normal camping except maybe we have to plow a little snow out of the way and on the last day I open the drain valve and will start draining on the way home. When I dump the tanks I will turn on the water and drain the rest into the tank. As soon as I get home I hook it up to my compressor and blow out all the water lines pour some anti-freeze into the traps, take out the water filter and spray hoses and we are ready for the next trip. It takes me about 20 minutes to get it ready for our winter weather. The hardest part is filling the tank in below zero weather from my garden hose.

update

I attempted to winterize today and for the likes of me can not locate the hot water heater bypass. Here is a pic of the valves located under and to the right of my queen bed.

I put 7 gallons of antifreeze in the fresh water tank and turned the pump on and could not get any of it to pump. I am assuming that maybe all of it is going into the hot water tank, or that the pump may be air-locked, or perhaps 7 gallons is not enough fluid for the pump to work? Any thoughts on this? I guess that if it is going into the hot water heater than It should be able to be drained back out through the drain on the hot water heater?

I would not have put the anti- freeze in the fresh water tank. You will need to thoroughly rinse this out before you drink any of the water from that tank and this will be a chore. The small amount of water that remains in the fresh water tank can freeze and cause no damage if it is drained completely. What you should have done is disconnected the inlet hose to your water pump and put that into a jug of anti- freeze. I have made a special hose out of aquarium parts. Those hoses and plastic fittings are the perfect size. You can then turn on the water pump and pump in a gallon at a time. I even have a on off valve on the aquarium tube to keep my siphon when I change the bottle of anti-freeze. Now I only do this when we have predicted weather of sub-zero, say like 20 or so below zero, otherwise I just depend on the pipes being blown clear of water with my air compressor as I have described above. The only anti-freeze I use is in the traps.
As for the by-pass to the water heater I am not sure about your model but I put mine right next to the water heater.
I wish I could send pictures but Chummy is in the shop right now getting some work done.

@CA Streamer: Hey I appreciate a little harmless ribbing. I wish sometimes that our weather here was more like weather down south and out west, but I do appreciate a good snow every once in a while.

@ Chap: Yeah, I know I should have just took the hose clamp off of the hose coming off of the intake side of the pump. I just read somewhere on these forums that you could just put it in the tank. I'm sure glad that I don't drink from the system. When I bought Nancy, I was advised by the rv tech not to drink from the system. He said you never know what kind of water is available at many campsites and that bottled water is relatively inexpensive to buy for cooking and drinking. Besides it took me a good 2-3 weeks to get the foul oniony smell out of the system after I purchased it. It kinda turned me off from wanting to drink any water straight from the faucet. Now it looks like next spring I'm going to be trying to purge the antifreeze smell and taste for a month. go figure!

Anyway, I hope someone with the same water line configuration could let me know where my hot water tank bypass might be located.
