Best RV Antifreeze 2020 - Buying Guide

Why Do You Need Antifreeze for Your RV?

If you are new to the RVing world, you may be wondering why your RV needs antifreeze. To understand the need for antifreeze protection, it is important to realize the plumbing system of an RV is not protected like it is in a typical brick and mortar home.

As temperatures begin to drop below freezing, the water in the plumbing lines will begin to expand and freeze. Because the frozen volume is greater than the flowing volume of the water, this can place extreme pressure on the pipes and cause them to burst.

Once the temperatures go above freezing, the burst pipes in the RV will release their water content, causing the potential for great amounts of damage. No RV owner wants to deal with this. Treating the water lines with antifreeze prevents this problem and stops freezing.

What Should You look for Before Purchasing the Best Antifreeze for Your RV?

There are many choices for purchasing the best antifreeze for vehicles. The standard rate of protection is -50 which is suitable for most cold climates. Most people are not going to need greater protection than this, but there are ratings that protect to -100 below zero.

It is important you choose an antifreeze that will offer corrosion protection and lubrication. Make sure you know what your pipes are made of before you purchase since some types of antifreeze are made for use with specific types of materials.

How to Properly Dispose of RV Antifreeze?

If your RV antifreeze is biodegradable and non-toxic, it can safely be disposed of down any sewer system. It should not be drained onto a lawn because it will kill your grass. When in doubt, contact your county hazardous waste office and ask for information on the laws governing antifreeze disposal. Many states offer recycling programs that allow used antifreeze to be collected, so it can be disposed of in a safe manner. Refer to your state, city, and county laws before disposing of any antifreeze liquid.

Some RVers dispose of their used antifreeze by pouring it over rocks so it can be dried by the sun. Most states allow for pumping of used RV antifreeze into the municipal sewer treatment lines, but it is wise to check the laws before disposal, to ensure you are not met with fines. 

Frequently Answered Questions About RV Antifreeze

We get many questions regarding the safe use of RV antifreeze and we would like to answer a few of the common ones. Hopefully, this information will answer some of your own questions and help you to understand the importance of using the best antifreeze available. If you have brand-specific questions, we recommend you defer these to the manufacturer.

Is RV antifreeze toxic to animals?

Unlike traditional vehicle antifreeze, RV antifreeze is not considered toxic to animals. Most brands are made from biodegradable materials and can be used around children and pets. Unlike other types of antifreeze, RV antifreeze is tasteless and does not attract animals. As with any type of antifreeze, caution should be practiced for safety purposes.

Is RV antifreeze safe for septic systems?

It is understandable for people to worry about the safety of antifreeze fluids. Because these fluids contain biodegradable materials, they can be used with any type of septic system and can even be flushed out into the municipal sewer system, as your particular state or county laws do not prohibit this action.

What is the difference between RV and regular antifreeze?

Many people believe RV antifreeze and regular antifreeze are the same, but they are entirely different. One of the biggest differences is regular antifreeze is toxic and should be used in closed loop cooling for engines while RV antifreeze is non-toxic and offers protection to the components of a plumbing system. Traditional antifreeze stays in an engine while RV antifreeze is pumped and flushed out once winter begins to say goodbye.
