Can I Put RV Antifreeze In My Freshwater Tank? (Answered)

It’s common to want to winterize the RV and make sure it’s protected.

To do this, you will come across a few viable options. Some will work and others are going to be unsafe for your RV.

You will wonder, can I put RV antifreeze in my freshwater tank during this process?

Yes, you can put RV antifreeze in a freshwater tank. To do this, only use RV-compatible antifreeze, pour it in slowly, and understand this is an inefficient method. It will require loads of antifreeze but it will work.

Most people will want to understand how much RV antifreeze is required for a freshwater tank but it will depend on the RV model.

It’s best to be prepared to use a tremendous amount during the process. However, the pump will work well in the tank and is going to push the antifreeze through as intended.

This guide will explain how to put RV antifreeze in a freshwater tank and what to consider.

How To Put RV Antifreeze In A Freshwater Tank

1. Only Use RV-Compatible Antifreeze

You will have to take the time to consider what is compatible and what’s not.

Using RV-compatible antifreeze is mandatory.

You should not be using any other type of antifreeze as it is dangerous for the tank and it will not work. It is toxic.

Once you have the right type of anti-freeze, you are then going to begin preparation to pour it in. Some people will prefer using an air pressure device to push the antifreeze into the RV.

This is a personal decision as the pump in the freshwater tank should suffice. It will manage well when the RV antifreeze is poured in.

As long as you are taking the time to use the right type of antifreeze, you are going to be in good shape and it will work out as you want it to.

2. Do It Methodically

This is one of the most important parts of the process.

You cannot rush this step.

You will have to be measured how you pour antifreeze into an RV’s freshwater tank. Otherwise, it is going to get backed up and/or ruin the tank.

When it comes time to take care of an RV or set up a new RV, you will have to think about what you are doing and how you are doing it.

This requires taking a little bit of RV antifreeze and then pouring it into the freshwater tank. Once you do this, you will get a better read on how the tank responds.

You can then begin to adjust and add more.

3. Avoid Using Automotive Antifreeze

This is a mistake that is commonly made and it is dangerous.

You should never put automotive antifreeze into the freshwater tank. This is not what it is designed for nor is it safe for the tank.

You are going to damage the RV.

It is important to avoid using this type of antifreeze and always make sure you are using the right option for your RV.

A lot of research goes into these formulations and you should only be using what works or you are not going to see appropriate results.

The more patient you are, the better your results are going to be.

This is what you will want to take the time to think about.

4. Consider The Efficiency Of This Method

Now that you are aware of the method and that it works, you will also want to think about the efficiency of putting RV antifreeze into the freshwater tank.

Yes, it will work.

However, does that mean it is the right way to go? Is this a solution that is going to work out for you and is going to play out as you want it to?

No, it might not be as efficient as you want it to be.

It is inefficient and it is going to use a tremendous amount of RV antifreeze. As a result, you will want to make sure you are prepared when it comes to what you are doing and how you are doing it.

This is often seen in various maintenance issues while handling the RV.

Final Thoughts

Can I put RV antifreeze in my freshwater tank?

You can put RV antifreeze in a freshwater tank. It is safe to do so. When doing this, always make sure to use RV-compatible antifreeze, pour it in slowly, and allow the pump to do its job. In some cases, an air pressure device can be used to do this.

It is important to do this methodically.

You should never rush adding RV antifreeze to the freshwater tank or you might not get the results you set out to get.

It’s common for people to make these mistakes when caring for an RV and that is why you will want to avoid them.
