What is RV Antifreeze and What Does it Do?
Before you jump ahead buying antifreeze, it will do you good to understand what it does and why it is essential for your RV. During winter, due to the drop in temperature, water pipes are at risk of bursting. Having the water system burst into your RV leads to a lot of damage, which will cost a lot to repair.
To prevent such damage from occurring, it is recommended you use antifreeze. It is a solution which is able to prevent pipes from bursting by offering burst protection for temperatures as low as -50°F. Using antifreeze means the water system pipes remain safe during winter.
How to Choose RV Antifreeze
While we are glad to share with our list of the antifreeze currently available for your RV, we would like to take a moment to talk about certain features to keep in mind when selecting an antifreeze.
You should opt for an product which offers effective protection against low temperatures. Go for a solution offering at least -50°F burst protection. There are antifreeze solutions which go even lower, but the -50°F mark is most common.
Keeping your environment safe when using chemicals, is crucial. The product you select should be non-toxic and environmentally-friendly. Such an antifreeze will also be safe to use around kids and pets.
The convenience means how easy it is for you to use. Greater convenience is offered by antifreeze solutions which can be used right out of the bottle without adding water to dilute it.
Variety of Uses
It is better to opt for a product which offers a range of uses. This means you can use it for your RVs as well as your swimming pools, boats, and vacation homes. Furthermore, antifreeze solutions which can work with a variety of pipes (plastic, copper, brass, etc.) are also recommended.

RV Antifreeze Types
The market is filled with different types of antifreeze for you to consider. These fluids are further divided into three different types. The ideal one for you depends on what you‘re using the antifreeze for and the situation. Here are the different types available for you to choose from.
Ethanol-based RV antifreeze, also known as an alcohol-based antifreeze for your RV, is a common option that is widely available in the market. You can easily find this product in most hardware and RV stores. It is not only effective but is also a cheaper option. However, it is flammable, so be careful when using it.
Propylene Glycol-Based Antifreeze
Propylene glycol-based RV antifreeze is another option that you can consider. This is loved by many, as it has a good effect on RVs. Although it is not that expensive, compared to the Ethanol-based one, you might find it a bit more on the pricer end.
This antifreeze contains non-toxic ingredients that make it safe to use for your RV plumbing. It also acts as a lubricant and helps in increasing the life of all rubber seals in the pipes and plumbing lines. Furthermore, it is non-flammable, which makes it a safer option.
Propylene-Ethanol Blend Antifreeze
This is basically a combination of the two types of antifreeze mentioned above. It features a standard price. It is non-toxic, which makes it a safer option for RV plumbing systems. Since it is a combination of the two above, you need to note that the amount of ethanol present in this antifreeze is unknown. Therefore, be careful when using this fluid.
Before making your final purchase, you must compare the different options available in the market to see which one would be the best option for you. This helps in ensuring that you’re making the right decision. And with so many options available, picking the right one out can be almost impossible. Most people are often still confused regarding the differences between different types of RV antifreeze and what sets them apart. Here is our attempt to explain these differences.
Swimming Pool Antifreeze vs. RV Antifreeze
Both swimming pool antifreeze and RV antifreeze are made using propylene glycol and are designed for preventing pipes from freezing. The main difference between the two is the color; while the swimming pool antifreeze is blue, the RV antifreeze is pink. The instructions for these two will likely differ, and so will the amount of water required for diluting them.
RV Antifreeze vs. Car Antifreeze
Most RV owners are aware of the fact that there is a huge difference between an antifreeze for a car and one for an RV. The main difference is that the latter is non-toxic and made to be used for the plumbing system. Meanwhile, automotive antifreeze is completely different. They are genuinely toxic and are meant to be used for the engine cooling system only.
Ethanol vs. Glycol RV Antifreeze
An RV antifreeze is a non-toxic fluid that is meant to be pumped into the plumbing system. The main similarity between ethanol and glycol RV antifreeze is that they help raise the freezing point of water.
The former is usually cheaper; however, it is flammable, which makes it unsafe to use. The latter is comparatively a bit more expensive; however, it is non-flammable, which makes it a lot safer.
Blowing Out RV Water Lines vs. Antifreeze
If you’re trying to get rid of the water from the water lines, you can use the blowout method or use an RV antifreeze. For the blowout method, you need an air compressor along with a blowout plug to expel the water from the system. Although it is the easiest method, it doesn't get all the water out of the system.
On the other hand, RV antifreeze is a more reliable method of removing water. This method ensures that all of the water is removed. For this, you will need around two to three gallons of RV antifreeze, depending on how big your RV is.
How to Put Antifreeze in an RV
In case you’re worried about how to clean your water tanks and how to make use of the antifreeze, here is a detailed guide for you to follow.
1. Clean the grey and black tank, drain them and fill them with fresh water. And then leave both the gate valves open so that they are completely clean.
2. Drain the water heater, open up the pressure relief valve, and relieve any pressure in the system. This disconnects the water, and there is no water going down the coach. The water pump is now off, and there is no pressure, so you can then close the relief valve and simultaneously take the drain plug out so that it doesn't blow out.
3. Now using an Atwood, a wood that has a plastic plug attached to an anode rod, take it out, and water will start coming out.
4. Then reopen the pressure relief valve at a quicker speed. When it's almost empty, go over to your freshwater city and close the pressure relief valve.
5. Look for your city water connection; usually, it's under the slide. Using a plug, screw into the hose outlet and connect your compressor to it. The compressor can be at 30 psi and will easily blow the air out. Make sure all of your facets are closed, and the air will blow out all of the water from the heater.
6. Once the water stops coming out, disconnect the air from the rig. Now, you can bypass the hot water heater and disconnect it.
7. Turn off the cold and hot water valves once, so that no water goes in or comes out. Then turn the bypass valve, so all the cold water will go into the hot water line without going into the hot water heater. That is bypassing.
8. At the city inlet, reconnect the air compressor and start turning on the faucets one by one to drain out all the water. This way, there is no water left that might dilute the antifreeze.
9. Now coming to the water bay, turn your whole house filter off and take it out. A little tip is that you can put an empty water bottle inside the filter so that you don't use too much antifreeze.
10. Place the housing back in.
11. Take the winterizing hose off. Now, take the RV antifreeze and stick the winterizing kit hose inside the bottom. Turn the water pump on to pressurize the system and turn the faucet on one by one. You'll see the colored antifreeze coming out. Now the hot water heater is done.
12. Go to the gate valves and close the grey and black water tank. Now, pour the remaining antifreeze down the drain. Make sure to wipe any plastic bits to prevent staining.
In case you are still confused regarding the procedure, refer to the following video to overcome your queries.
We hope our best antifreeze review list was able to help you know about the antifreeze options you can spend your money on. As mentioned, it is important to buy an RV antifreeze which is reliable because you don’t want to end up spending a lot of money on repairs due to burst pipes.
People Also Ask
Some of you might have specific questions related to the topic of RV antifreeze solutions. We are going to do our best to answer these questions to the best of ability. As an RV owner, it is essential you are proactive when it comes to the proper maintenance of your RV, especially when protecting the water system during winter.
Now before you make your purchase, you might still be curious about certain things. Buying the right antifreeze for your RV can be quite a difficult task, considering all the various options that are available. It can get quite confusing. But don't worry; here are a few questions that most people ask before they purchase an antifreeze for their RV. You can go through them to clear your head of any queries.
What is the Difference Between RV Antifreeze and Regular Antifreeze?
You might be surprised to learn how many people think a regular antifreeze and an RV antifreeze are the same. You need to realize the two are different. Regular antifreeze is poisonous and toxic to people, animals, and the environment. It should only be used in closed loop cooling for engines. RV antifreeze, on the other hand, is non-toxic and protects the water system. Also, RV antifreeze gets pumped into the system and then flushed out when winter begins.
Is RV Antifreeze Safe For Septic Systems?
Yes, a reliable RV antifreeze can be safely used for any type of septic tank. This is because an RV antifreeze has biodegradable materials. Such an antifreeze can also be flushed into the municipal sewer system (as long as there is no law prohibiting such an action). You should always go for an environmentally-friendly RV antifreeze.
How to Dispose of Antifreeze
RV antifreeze, which is non-toxic and biodegradable, can be disposed of by being flushed down into any sewer system. Make sure that you don't drain it all into the lawn. Even though such an antifreeze is environmentally-friendly, too much of it can harm the grass growing in the lawn. You can also drain it on rocks and let it dry up in the sun. It is recommended you check with your state laws.
What is RV Antifreeze Made of - Is it Safe?
In general, a non-toxic and safe RV antifreeze is also known as a propylene glycerol antifreeze. Such an antifreeze solution is made of propylene glycol, glycerol, water, and dipotassium phosphate. A dye is also added to help detect any possible leaks which may occur. The biodegradable components of antifreeze are what allows it to be environmentally safe.
What Does Antifreeze Smell Like?
RV Antifreeze does have an odor to it. Such an antifreeze is known to smell, as well as taste, like maple syrup. While the scent isn't too overpowering, some people might not like it. We have mentioned certain antifreeze solutions in our RV antifreeze review list which can give off an irritating odor to some. Also, not flushing it out properly can lead to the smell and taste lingering.
Where Do You Recycle Antifreeze?
The correct answer to this question can be obtained by referring to any existing laws about recycling antifreeze laws in your state, city, etc. There are many states that offer antifreeze recycling programs. The important thing for you to do, as a law-abiding citizen, is to know how to recycle antifreeze properly. Do not merely dispose of it on the lawn or carelessly try to store it away in a non-airtight container. Also, remember that this antifreeze is not the toxic kind used in engines, so may be subject to different guidelines.
How Often Should You Change Your Antifreeze?
In order to properly winterize your RV, you need to know how often you should change the RV antifreeze. It is generally recommended that you change your antifreeze at least once as winter approaches. Using two to three gallons of a reliable RV antifreeze should be enough to keep the water system safe during winter. However, you might need to use more depending on the length of the water system.
How Much RV Antifreeze to Winterize?
Knowing how much RV antifreeze you should use to winterize properly is crucial. Using too little won't be able to protect the water systems effectively. Using too much isn't recommended either and will only increase your costs. The amount of RV antifreeze needed to winterize the RV is dependent on the size of the RV as well as the overall length of the water lines. Usually, two or three gallons of RV should do the trick.
What Happens if You Use the Wrong Color Antifreeze?
The color of the antifreeze is really not a reliable indicator of how compatible the fluid will be; therefore, it is always better to read the packaging to confirm whether it is suitable or not.
If you end up using a different-colored antifreeze without removing the previous one you used, you will notice that the two will not mix well and will end up forming a gel-like substance. This gel-like substance causes blockages, causing the engine to overheat and damage the radiator, water jackets, and the heater core. Moreover, at times, even the water pump overheats and fails.
What Color is RV Antifreeze?
There are many different-colored types of antifreeze available in the market. Each of these fluids is made for different types of vehicles. RV antifreeze is usually pink; however, you see some in different colors, such as blue.
You should have a look at the temperature rating before you purchase one for your RV. Make sure to go through the instructions and see which fluid is recommended.
How Do I Get the Antifreeze Out of My RV?
You can easily remove all the antifreeze from your RV by flushing it out of your plumbing system. The easiest way to get rid of all the antifreeze is to run fresh water through the system. For this, you can make use of the city water inlet or the freshwater holding tank. Run fresh water through all of the faucets, both hot and cold, until the water flows clear.
All of the antifreeze residue will be in the holding tanks, which you can later empty at a dump station. And if, for any particular reason, you have added some RV antifreeze to your freshwater holding tank, then you will have to drain it before you add any potable water to the tank.
At What Temperature Does RV Antifreeze Freeze?
The freezing point of antifreeze is basically the temperature at which you’ll start noticing ice crystals forming in the undiluted fluid. The freeze point measurements are usually given using both refractometers and hydrometers.
However, it is important to understand that the reading may differ by several degrees from what is stated on the product due to its surrounding temperature or because of the age of the product. Therefore, a -50°F product might be expected to have a reading of +12°F, but instead, you might see a reading that falls in a range of +12°F to +16°F, so it depends on a few factors.
How to Get Rid of RV Antifreeze Smell
Most RV antifreeze have an odor. The smell is similar to that of maple syrup, and while the scent isn't overpowering, it might not be everyone’s cup of tea. And if you don't clean your tank properly, then the smell will linger. Therefore, the best way to get rid of the smell is to flush the tank properly until all the water being flushed out is clear, and there’s no small.
How Many Gallons of Antifreeze For RV?
When winterizing your RV, it is important that you know how much of the RV antifreeze you will require. Using less quantity won’t help in providing protection to the water systems, and using too much is not recommended. The amount you will be using mainly depends on how big or small your RV is and on the overall length of your RV’s water line. Mostly, you require two to three gallons.
How Much RV Antifreeze Per Gallon of Water?
The amount of antifreeze you use depends on the size of your RV and how big your pipelines are. Usually, one requires around two to three gallons for your water tank.
