Question on winterizing Rockwood A122BH A Frame

Hello Folks,

This is our first year with an A Frame trailer, (or any RV), and I need some feedback on a question regarding winterizing.

Here in Bend, Oregon we do get snow in the winter, though it doesn't get below the teens, and usually never below the mid 20's. My question is this:
Since we don't have a black water tank, is it sufficient to just drain the hot water and fresh water tanks and the water lines? I've read many posts that talk about putting antifreeze in all the water lines for the winter, but if all the water has been drained, why would this be necessary?

I'll appreciate any feedback you all can offer on this, and any other ideas you may have for us on getting it ready for winter.

Many thanks!

Other A frame owners should chime in, but i can tell you the why. Draining the water systems won't get all the water out, and any water left that freezes risks bursting lines or connections, or busting the water pump. Pushing the pink stuff through is pretty cheap insurance.

The issue is your faucets and water pump. Just draining will leave water in them. If it gets cold enough for long enough they will be damaged.

As others have said just draining lines will leave water in low points in the lines, water pump, and elsewhere. I would drain the tanks, by-pass the hot water tank, pump antifreeze through the lines and drop a little antifreeze into the drain p-traps.

Peace of mind for the rest of the winter.

The cost and effort to winterize with "Pink stuff" is considerably less than the cost and effort required to repair a burst fitting or line. If you have an outside shower don't forget to do it as well. You should not need more than 2 Gal ($7.00) of pink stuff to protect everything.

I don't use the special hose that is illustrated in the video.

This how I do my T12-RBST which is a sister model to the Rockwood A-122 series.

1. Open up the fresh water drain valve.

2. Open up the hot and cold low point drains near the water heater under the seat next to the Stove and Fridge.

3. Open both hot and cold sides of the sink faucet.

4. Open up both sides of the outside shower control.

5. Open up the water filter under the sink, remove the filter element, re-install the filter housing.

6. Let everything drain until water stops running, then close all the open devices.

7. Set the water heater bypass valves (all 3 will be turned in the direction opposite of normal usage position).

8. Note that you can dilute the pink antifreeze depending on expected lowest temperatures. I use Minus 50 degree antifreeze diluted 1 to 1 with water which should protect to minus 9 degrees. I put 2 gallons full strength into the fresh water fill, then refill the empty bottles and add 2 gallons of water.

9. I now turn the water pump on, then open one tap at a time until it flows a steady stream of pink. The flow into the inside sink will give you protection for the drain trap. I remove the shower head on the outside and run the solution back into the fresh tank inlet.

10. DONE

Many thanks!

Thanks Bluepill! Very easy to follow, and I appreciate that advice comes from someone who has pretty much the same rig!

All the best to you....

I posted a response to a similar question in another thread.
I use air to winterize.
The discussion is slightly different, but you may find it helpful.

Winterize your camper...regardless of the method. PEX lines can endure a lot of stress, but the plastic connectors will pop like broken eggs if water inside freezes.
