Winterizing RV - How I Do It

I thought this might be helpful to our forum members especially for new RVers.

RV Winterizing….Blowing Out the Lines Method.

You will need an air compressor or some source of air with an air hose.
An air hose chuck.
A water inlet / air adapter.
And less then a gal. of RV antifreeze.

1. Drain fresh water tank, close valve.
2. Drain hot water heater replace drain plug.
3. Dump and (flush if possible) both black and gray water holding tanks, leave gray water valve open.
4. Screw compressed air adaptor into the fresh water inlet. The adapter is available from Camping World or most RV dealers.
5. Apply compressed air, keeping the pressure at 30 PSI but less than 40 PSI. You may need someone to hold the air hose on the adapter.
6. Open then close each faucet, hot and cold, one valve at a time, allowing the compressed air to force the water out of the line. Don't forget the shower and toilet and outside shower. Open both low point drains and close.
7. Remove the drain plug from the hot water tank and allow the compressed air to blow out the remaining water. Reinstall drain plug.
8. Remove the compressed air source and adapter. 9. Close gray tank valve.
10. Pour a few cups of RV antifreeze down each drain and toilet.
11. You’re done.

I'm struggling with winterizing right now. I'm trying to pump the anti-freeze into the lines but it's not going. Do you always just use air? Obviously you have not had any problems or you would not go that route.

I use to do the antifreeze method but for the last 10 years or so I use the air method, much easier and quicker.

I really urge caution on using the air method. I have seen too many units that have had frozen lines because of moisture left in the lines. For what it costs a couple of bucks worth of anti-freeze should give you peace of mind.
Redwingsfan, there must be an explanation as to why the anti-freeze is not going through. I would stop in at any RV dealer and one of the techs should be able to give you the right advice.

The air method works just fine as long as you keep the pressure within bounds. As for going the anti-freeze method find the tube at the water pump that will let you put a funnel in one end, then turn the pump on and slowly pour anti-freeze in the funnel with the facets open (furthest distance from pump first) until the lines are full. Should take all of 10 minutes once things are hooked up. If the anti-freeze just won't go in there's something wrong with the pump or a blockage in which case you need to have it looked at, as mentioned above.

You shouldn't need a funnel. Just stick the tube in the jug of antifreeze and the pump should suck it out.

I'm a newbie and tried adding antifreeze for the first time tonight. i too had trouble with getting the suction to start, but it finally kicked in. a couple of questions:

1. My pipes are clear plastic and I can see which ones have the pink fluid in them. After adding the antifreeze, only SOME of the pipes showed fluid and some had fluid in parts of the pipe. Is this normal? However, I was able to get pink fluid to come through all of the taps and the toilet.
2. My Jay Feather Sport took about 2 jugs of antifreeze. Is this normal? I'm sure I bypassed the hot water heater, so I don't know where all the fluid went.

Thanks for your feedback.

Thanks for all of the responses. I knew I would get the help from the group. I finally did find the problem. The owners manual was just about useless as far as this process goes. Using the phrase "attach garden hose to city water connection" starts the process outside of the RV. Reading old posts from this site I realized there had to be a way to get near the pump and there was. Under the dinette. The manual stated nothing about removing the dinette access panel, closing the valve from the fresh water tank, opening the valve to the clear hose provide specifically for sucking the anti-freeze...Oh well, it's done now. I went through about a gallon and then some of the pink stuff and feel pretty confident that I am covered. I still have concerns that the HWT is not completely drained. Can I blow air through the pressure relief valve and force it out of the drain plug hole? Ray364 the tubes that I could see looked pretty full of the anti-freeze, except by the hot water tank. I'm assuming that has something to do with the routing around the bypass.

as long as antifreeze comes out your faucets you have pushed all the water out
