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.
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.
