Most Affordable

Winterize RV Quick-Connect Plug

Sure, it’s affordable, but the Winterize RV Quick-Connect Plug is also environmentally-friendly as it does not use antifreeze.

Made from brass, it is also lead-free. Lead-free brass is harder, stronger, and more durable than regular leaded brass so this product can last a lifetime. And even though manufacturing this type of lead-free brass costs more to make, the company has decided to absorb the cost to keep their customers safe as an added bonus.

We also love this winterization kit because it not only works on recreational vehicles but also boats, watercraft, campers, RV waterlines, and travel trailers. It can even work on your sprinkler systems, drip irrigation systems, soaker hoses, faucets, pipes, spigots, sillcocks, water garden hoses, RV waterlines, and siphon hose bibbs where applicable. It easily attaches to the city water lines or a standard garden siphon hose, making for a quick setup.

Best Pump Converter

Valterra Lead-Free Pump Converter Kit

This lead-free pump connects inside the RV next to the RV water pump and automatically enables your water pump to winterize your water lines. The price point is middle of the road compared to the others on our list, but it is simple to set up and easily converts your RV water pump into doing most of the work for you, which is why it’s our best pump converter on the list.

Small and compact, this winterization kit is easy to store in any toolbox and take with you. However, many users have complained that it can be difficult to set up because it attaches to the water pump, which in some recreational vehicles can be hard to get to and a bit tight.

In this kit the siphon hose and the fitting is brass, so you need to be careful when attaching them. Some users have stated they wished both pieces were brass for ease of connection.

Recap: The Best RV Winterization Kits

What to Consider When Buying a Winterization Kit

Now that you know why to winterize, how to winterize, and what products to help you winterize your RV, you’ll need to consider a few questions before you make a purchase.


The first question you should ask yourself before purchasing an RV winterization kit is your budget, and what are you willing to spend. Also, what is included in the cost of the kit? Do you need to purchase any other parts or attachments to make it work for your needs? Other parts and attachments will add to your overall cost. The components included will also determine which kit is the right one for you.


By reading your owner’s manual for your RV, you can tell what you will need to RV winterize your vehicle. Some of the kits out there come with everything you will need from start to finish. In other cases, you’ll pick and choose what your rig and pipe or electrical setup require.


The next thing to ask is this kit compatible with what you are using it for and your specific RV. Make sure you read up on what you need for your specific RV or needs before making a purchase. The last thing you want to do is buy a winterization kit that does not work for your motorhome, travel trailer, or fifth wheel.


Some kits have everything you need right out of the box and will help you winterize your RV from start to finish, some do not. Some are also easier to install than others. Before making a decision on which kit to go with, determine how much time and energy you can and are willing to spend winterizing your RV. It may be worth more money to get a complete kit if it saves you time in the end.

Ready for Winter?

Whether you’re hunkering down in your RV for the winter or storing it out in the elements, proper preparation is essential. With one of the best RV winterization kits available, you can rest easy all season. When spring comes, you’ll be glad you made the investment and the effort.

FAQs (Frequently Asked Questions)

How much does it cost to winterize an RV?

If you go to a dealer, they will winterize your RV for you for anywhere between $100-$300. However, you can winterize your RV yourself for much cheaper than that. Our article will give you the best complete kits to make sure that your RV is winterized appropriately and can handle the cold weather that you will most likely experience when you travel in the later months of the year.

Can you winterize without antifreeze?

You can winterize your RV without antifreeze in a couple of different ways. If you are not going to be spending a long time in the freezing weather you may not need antifreeze. Also, if where you are going only gets cold at night you might also not need antifreeze. One of the easiest ways to make sure that your pipes are clear without antifreeze is to blow them out with compressed air. This will ensure that any remaining water or waste is pushed through the pipes so that they can’t freeze over.

Will RV holding tanks freeze?

This depends on where the holding supply tanks are located. If it is right under the floor of your RV, the residual heat from the floor will help to slow down the freezing process when temperatures really dip. If it is located somewhere further away from the floor then it is likely to freeze and this can cause substantial damage to your RV because liquids expand when they freeze which could burst your holding tank.
