Yeah, this thread is a classic example of how we all waste our time. Rephrased it asks, should I trust that the pink stuff will do what it says, despite the fact that it has been used that way for decades?

While you're staying warm and cozy, you might contemplate if asking others for their thoughts is healthy for you, given that proper answers they offer make your head hurt.

What you very much do *not* want is a faucet or fitting filled with water. That will indeed be a problem. The same thing is true of a hot water heater with water in it.



Even if you do use pink stuff, the hot water heater normally just gets a drain / blow out and shut down. That's what the manufacturer recommends, that's what a whole lot of people do. Properly done, it works.

When my trailer was delivered brand spanking new it most certainly did have RV Antifreeze in it, did you buy yours new? And my manual doesn’t state that you can only use one method of winterizing.

For over 25 years, I have used the air method with adding -50F anti-burst to the sink and shower p-traps.

Yes, the dealer does put the pink stuff in at delivery, however there are 2 ways to winterize, air or the pink stuff. In the end it's your call what you do. I just know I use far less pink stuff using the compressor and blowing out the lines. Neither method is bad, using air is my personal choice.

Don't need to make the water heater bone dry either. There too, just need to get most of the water out. In over 25 years, never had a cracked tank (non on demand style heater).

I do agree, we've taken a very basic annual function for the northern climate folks and turned it in to a Chevy vs Ford convo. It's not rocket science.

My F250 sure pulls my trailer a bunch better when I use the pink antifreeze especially when I don’t bypass the hot water tank. The added tongue weight helps my Hensley hitch setup. I find that when I just use the air compressor in the waterlines, there is just too much uplift and I have to compensate by deflating my marathon tires from 120 psi to 25 psi.

Seriously, it wasn’t until we moved to the Chicagoland area did I blow out the lines AND use antifreeze. In 2014 during the polar vortex, we went 23 days straight with temps that didn’t go above freezing. In the 2015 polar vortex, we had 30 hours where the temps didn’t get above -0f. After those two winters, I decided not to deviate from what worked for me.

Thanks PanAm! I wondered when this would get there.

I hold my tires for a good ten years in a sunny place before ever using them. I want to make sure the tires cure and off gas. When they start showing signs of cracking, then they are good to start to use them.

Now to more serious subjects, many occasions call for a tandem dry / dropper rig.

10 degree overnight and no problems open container with antifreeze in it catching the fill up of lines and not frozen. Even if 'slushy' it is better than frozen expanding water in the lines and fittings. Pink is good.

Freezing Antifreeze

SpartanGuy, you set your “pink stuff” jugs down on a heaven-facing radiator, your concrete sidewalk. Think black ice.

On clear, still nights, in the wee hours, flat horizontal surfaces reach lowest temperatures of the day as the heat RADIATED to the thermally COLD heavens is not CONVECTED or CONDUCTED back at the same rate lost. Thus, with air temperature no lower than 42 degrees Fahrenheit, the ancients were able to freeze 3 inches of water in a shallow trench on the north side of an East-West running wall.

Your jugs were chilled to a temperature much lower than the night air by contact with a freezing sidewalk. With any moisture at all, the roof of your car—and your roof itself—would be covered with frost. (But not the sides of your car . . . as the sides of your car are not facing cold heavens but facing equally warm objects.)

So, to fairly test your pink stuff, place the jug up off the ground and under an overhang. I think you will find it still liquid in the morning.

From time to time people complain about the pink stuff, usually about the aftertaste. It may be the cheapest bottles of pink stuff do have a taste, but I’ve used a variety of brands and never noticed a taste. Maybe flushing out the lines in the spring needs to be more thorough to get rid of the taste. I would think flushing with a chlorine solution and then flushing that with clean water at least twice would remove the antifreeze taste. Another clean water flush is usually necessary to get rid of the chlorine taste.

I blow out the lines until most of the mist disappears. I do so at 60 psi because that is standard city water pressure. That you may get lower or higher pressure at your house is probable. 60 is only an uncommon standard. Then I pump pink stuff through the pipes, but not the water tank or water heater. So long as you get all the water out of the heater except for the gallon or so at the bottom, it will not freeze. It is made that way. I think it is good to flush all the water out of the heater in the spring to get debris out of the bottom, but it is hard to do. The water tank does not need antifreeze because once emptied there is little in it to freeze. Pouring a cup of liquid in may keep the drain valve seal more flexible if there is one. There are commercial liquids available to keep all such valve seals in good shape. We have used them sometimes, but never had a problem either way.

While keeping all the faucets open may be helpful, I am unsure if I have left them open every winter. Nevertheless, I haven’t had any problems. Since our first RV, we have done this the same way. Temperatures some winters have dropped below —20 F. You can’t leave the toilet valve open and I did have it freeze the first winter when I didn’t think of running antifreeze through it. Same for the kitchen sprayer. The little bit of water left in the lines will migrate downhill and sometimes pool in a low point. I think a poor job of blowing out the lines would be necessary for enough water to collect to blow a pipe, but don’t want to find out by doing a bad job.

I understand that draining the pink stuff after running it through the lines would probably clear all the water out, it seems to be similar to leaving it there all winter. It was stated above water expands 8% when it freezes, but I have always read the expansion is 11%.

The first times I winterized and summarized I was nervous about doing it right. The consequences of not doing it right are not good. As I said, I didn’t do it right for getting about the toilet valve and the kitchen sprayer. Since everything has been fine. You’ll figure it out and move on.

You have it backward. Auto-type antifreeze is Ethylene Glycol, which is extremely poisonous and sweet. Propylene Glycol is food-grade.

I used to work in a champagne winery where we had to freeze the necks of the bottles in order to expel the dead yeast. Before I changed to a machine using Propylene Glycol we used salt brine. Both are food grade but Propylene Glycol is a lot less corrosive and is approved by the FDA for human food production uses.

BTW, Evans Waterless Coolant in Propylene Glycol with some lubricants added for the water pump.

I learned in the 70's that pure antifreeze will freeze without some water added.....

Could You Repeat That, Please?

As the slush forms the total volume of the now mixture (part solution, part pure ice) does expand so it is incorrect to describe this as anti-burst, but because it is still larglely a liquid and continues to have low surface tension the expansion can take place in a way that some of the mixture pushes out. This is why faucets are left open (you do leave the faucets open right?).

Anyway propylene glycol is used even though it has this annoying behavior because it does not metabolize to formaldehyde in your liver like ethylene glycol or rubbing alcohol and it does not permeate into plastics and rubbers like ethanol (grain spirits) does, and then come back out with nasty aftertastes the other popular food grade antifreeze.

Mistrust of the pink stuff confirmed?

I promise I tampered with the solution in no way and removed the seal just today. As frozen inside as a slushy from 7-Eleven. It got down to 12 degrees last night, not -50 btw. Bottle was full, poured some out on my ice spot (not sure if that’s kosher or not, but not the topic at hand either way)

Thoughts anyone?

It will freeze but it DOES NOT EXPAND. That is what protects the plumbing

I said the pink stuff is effective antifreeze, don't let the slush scare you away, anyone who says different is wrong.

AHA! I guessed correctly!

I might respectfully add that anyone who says wrong, is different.

YO! BIKER! Help us explain that the concrete, due to chemicals within the concrete, plus the science of geothermal energy from ground contact, actually makes the temperature of the concrete warmer than freezing air, and even more so, if solar energy is in contact with the concrete surface.

We Bikers need to hang together, and share our enlightenment.
