RV Winterizing Kit Buyer’s Guide

Ease of Use

The ease of use of your RV kit is definitely something to consider when weighing your options. Some are easier than others to install, of course.

But the ones that are more complicated to install may require more than one person to get working, which is important to know if you like to trek solo!

However, if having multiple people on hand to help winterize your RV isn’t a problem, then you might be in luck with some cheaper options for RV winterizing kits.

Winterizing an RV

Model Compatibility

Compatibility is a huge factor when surveying the RV winterizing kit choices available to you. Do you need a male or female adapter? A certain PSI? A specific width of the hose or valve size? Does your RV only work with a certain brand of air compressor?

These are all important questions to ask yourself before purchasing your RV winterizing kit!

Permanent or Seasonal?

Just like there are different models and sizes of RV winterizing kits, there are also different methods of installation: permanent or seasonal.

A seasonal by-pass kit allows you to hook your kit up to the water heater and then remove it in the spring.

A permanent kit, however, can’t be removed after the winter is over. You just adjust it accordingly by cutting certain valves on and off.

Ultimately, this choice is up to preference! If you live in a particularly cold climate and find yourself needing to consistently winterize your RV every year, then a permanent hookup might be the best option for you.

But if you live in a warmer area where your RV rarely needs to be prepped for freezing temperatures, then a seasonal kit could be a better choice!

Length of Hose

Not all RV water systems are made the same! Depending on the model you have, the space you have to work with in installing your winterizing system might be limited.

If so, you don’t want large adapters and stiff hoses that make accessing the parts you need almost impossible. Ultra-flexible hoses are what you’ll want to look for in your search for a winterizing kit.

But, in some cases you might need a long stiff hose to get into the area where you can attach your kit. It’s good to assess what you need beforehand so you know the style of hose to look for.


Most RV winterizing kits are made of brass and reinforced rubber or plastic.

However, since the kit will be sitting for sometime while your RV hibernates for the winter, you want to ensure your kit is corrosion-resistant, durable, and made of quality materials.

Something else to look for when checking out the materials is lead-free brass valves and adapters. The last thing you want is harmful chemicals near your water supply!

RV Winterizing Kit Frequently Asked Questions

What is the difference between male and female connections?

Male connections are typically what comes to mind when you think of a plug, and as such, female connections are the socket or outlet.

In this case, male connections for winterizing kits are pronged, and female connections have a space to insert the prong. It’s important to know what kind of adapter or connection you need in order to correctly set up your kit!

Otherwise, you’ll need to find either a male or female adapter in order to make your kit function properly.

Why do I need an RV winterizing kit?

Pipes or lines in your RV are susceptible to freezing or busting just like in your house where you might prepare the pipes for colder temperatures by dripping taps.

Since your RV is both your home and vehicle, you need to prepare it for winter, too!

This is where a winterizing kit comes in handy. You can use it to help flush the waterlines in your RV and keep them from freezing.

Winterize RV

Do I need an RV winterizing kit with a gauge?

Not necessarily, but you’ll be using an air compressor to blow the water out of the lines, so you may want one to monitor the pressure.

Different RVs require different things, and various winterizing kits function variously, so a gauge may not be necessary.

If you’re not super familiar or comfortable with the winterizing process yet, you may want to have a kit that includes a pressure gauge just to be sure.

Should I use antifreeze?

Again, different kits will require different things. Some winterizing kits will specify that they don’t require antifreeze, which is a much more environmentally friendly option.

Antifreeze is a chemical compound that is toxic to plants and animals. Though a necessity for many vehicles, it should be handled with care!

Kits that don’t require antifreeze are definitely an environmental win, but they may not have the same efficacy as the ones that do.

Additionally, you can experiment with marine-safe, non-toxic anti-freeze and see how that works in keeping your RV in good shape through the winter.

Final Thoughts on RV Winterizing Kits

Whether your RV is your seasonal or permanent home, it needs careful attention throughout the winter season just like a house would.

Luckily, there are plenty of winterizing kit options out there to fit your budget, need, skill level, and preference.
