What Is An RV Antifreeze And How Does It Work
The RV antifreeze is a simple and straightforward product that works wonders for protecting our pipes and plumbing system from damage happening due to the water inside them freezing in the winter.
As you might already know, preparing our rig for the coming winter is one of the most essential maintenance activities that we need to do annually. Hence, RV antifreeze is a must-have product that new and seasoned RVers must have in their winterization kit.
This product offers general protection for our pipes at a specific temperature rating (e.g., -50 degrees Fahrenheit). It works by saving us from dealing with water damage due to burst pipes. Using it, we don’t have to spend a lot of money on the repairs or replacement of RV pipes and tubing.
The antifreeze works by introducing new molecules in the water. It blocks natural and attractive forces while delaying and preventing molecules from forming and turning into crystalline structures. In this case, the lower the temperature can go before this solution will freeze with more of these new molecules from the antifreeze being introduced into the mix.
So, the antifreeze can prevent the chain of events that will lead to the formation of crystalline structures, which will later freeze the pipes. However, you must understand that antifreeze solutions are with temperature ratings that indicate the level of temperature/freeze protection they can provide you with. For this reason, you need to determine the right temperature rating that suits where you are living or possibly winter camping.
Now, you might also be asking, does RV antifreeze go bad? Generally, they don’t go bad, but it can start losing effectiveness after one year in storage. There are also antifreeze solutions that you need to use in one go. Check the label for proper guidance on this.
Types Of RV Antifreezes
There are different types of RV antifreeze that you can find in home depot, Lowes, and other places, so you should check and read the label. In terms of temperature rating, you can find different products ranging from -20 degrees to -100 degrees F. You must consider this depending on where the RV is sitting for storage.
For the chemical composition, we got three types of antifreeze concentrates.
- Ethanol-based RV Antifreeze: These types of RV antifreeze can be the cheapest option of all, but it can also be the most harmful one for the RV. This type can dry out the rubber seals in the pipelines and plumbing. The ethanol blend RV antifreeze can also affect water quality, taste, and smell. Finally, this type is alcohol-based; thus, the ethanol blend RV antifreeze is also highly flammable.
- Propylene Glycol-based RV Antifreeze: These types of RV antifreeze are the most preferred because it is generally safe for the RV plumbing system. It is not flammable and does not alter water quality. It also doesn’t leave an annoying odor in the tubes and plumbing system.
- Ethanol-and-propylene-based antifreeze: It is also generally safe, but again, it has alcohol – whose downsides are mentioned earlier.
Benefits of using RV antifreeze
Why do you need an RV antifreeze? RV winterization is very important to prepare our recreational vehicle plumbing system from breaking and bursting due to water inside them solidifying, causing their expansion and possibly rupturing later. We don’t want that to happen, and maybe that’s the least we want to deal with because it will be too much of a hassle.
This RV product can also help us detect any leaks because most varieties are pink in color. They’re visible enough to see if there are leakages that would otherwise cause damage to the RV flooring, too.
Convenience is another advantage of using an antifreeze. RV pipes are fragile and it can be hard to reverse any damage that can go unnoticed in the winter, especially that many RV shops can be on holiday.
It’s why you need to be ready with this product before the winter so that you can quickly and readily add it to your plumbing system. That’s very convenient other than having to buy and applying it in the winter itself.
How We Picked
One of the biggest challenges that we face as RV owners is the wintertime. It’s the season when the temperature is at freezing levels, causing damage to the pipes. They can even break and burst and lead to major damages during winter or storage. That’s why we need a reliable RV Antifreeze!
However, it’s probably one of the most overlooked and misunderstood products in the RVing world. Some of us might think that an automobile antifreeze is enough to perform the antifreeze protection we need for our plumbing pipes and tubes, but they’re not.
They can even be harmful to cause damage to our tubes and RV components. In the following, I have put up a buying guide to give you an insight on how we picked the right RV antifreeze for your recreational vehicle, trailer, boat, vacation home, or any other closed water system.
What’s the temperature rating?
Not all RV antifreezes are created equal, and again, you need to choose one that matches your situation, like where your RV is sitting in the cold winter. Temperature varies from one place to another, and that’s precisely why you need an antifreeze that can keep up with that.
The major factor to consider when choosing the antifreeze is its temperature rating. It refers to how strong it is under a specific temperature range. For example, most of these products have a rating of -50 degrees Fahrenheit burst protection. It can give you peace of mind that your RV will be safe for storage or wintry condition at that maximum temperature.
A -50 degrees, F rating means that the product will react to that temperature. It’s also the rating up to until it will become a slush inside the tubes and pipes. One of the significant advantages of using this product is that it can protect the pipes from exploding that happens due to the expansion of the liquid that turns solid inside them.
There are different variations for a temperature rating, and that’s one thing you need to check when comparing your options. It largely depends on where your RV is sitting in storage or winter.
I’d like to note that this product might fare better when not diluted in water because it will come as a pure concentrate to add to the plumbing system. It can add more protection to your plumbing system come the winter. I’d say that these variations can come in -20, -50, or -100, with the last one being most suitable for people in elevated and colder locations.
What’s the type of the antifreeze product?
Okay, this can be quite tricky and maybe confusing for some. At the very least, the choice will depend on your situation and usage/purpose.
There is an ethanol- or alcohol-based antifreeze. You can find them in all sorts of RV shops in your area, and undoubtedly the cheapest option available, but cheap can also mean it carries a couple of downsides when used in an engine cooling system.
The most common one is drying out the rubber seals in the main lines, including the toilet and faucet lines. Also, I do not like the annoying smell coming from the pipes. That’s not all because they can also alter the taste of your water supply.
Another is its high flammability. You must be extra careful when using this antifreeze, or you might end up catching fire in your RV. You must not use it near cigarettes or fires.
Another type is the propylene glycol-based antifreeze, which is one of the best out there. While it may be a bit pricier than ethanol antifreeze, it does perform quite well. It is nontoxic and safe to use around with kids and pets. Plus, it can extend the life of your rubber seals. Best of all, it’s not as dangerous as an alcohol-based product because it is not flammable.
The last type being the combination of ethanol and propylene antifreeze. The propylene ethanol blend can be safe to use for an RV at a standard price. The problem is that the propylene ethanol blend contains ethanol, which quantity is also hard to tell.
So, for the best results, I recommend going to the propylene-glycol-based antifreeze as one of the best. It can offer better protection and more safety. That’s what we want, anyway.
