It’s a little difficult for water to flow in an RV water hose when the water itself is frozen. Scratch that. It’s impossible for water to flow when it’s frozen. When using an RV water hose during colder months, the goal is to prevent the water from having the chance to freeze.

Only Mother Nature can regulate temperature, though, so it’s not as if you have control over how cold it’s going to be while you’re camping. So, with that said, how to keep RV water hose from freezing? It depends on how much work you want to do.

Well, that was sort of a cryptic answer, right? Indeed, but don’t worry as we’re going to dive headfirst into it. Firstly, however, we need to talk about something important.

At what temperature will an RV water hose freeze?

Everyone’s been taught that water begins to freeze at 32 degrees Fahrenheit. That is the general established freezing temperature of water. Logically, that would then mean that you need to worry about your RV water hose freezing at that point.

While there’s certainly some truth to that, it’s not as if as soon as the temperature hits 32 degrees Fahrenheit, the water in your hose is going to be rock solid. It’ll take a minute for the water to actually freeze especially if the temperature starts to fluctuate a lot.

When it begins to get really cold outside, like in the single digits, that’s when the process is going to quicken, and that’s really when it starts to get problematic more quickly.

How to keep RV water hose from freezing?

Remember how we said that this question depends on how much work you want to do? In order to keep your RV water hose from freezing, you can either rig something up yourself or just opt to buy a specific type of water hose online (or at your local RV store, possibly).

To start, we want to explain a really good way to rig up your own DIY heated water hose. If you want to do it this way, however, just know that you’re going to need a few different items.

1. One of the best ways to heat up your water hose is to use heat cables. In order to ensure you get enough cable, measure the entirety of your water hose, and record this measurement as that’s how much heat cable you’re going to need. Hopefully, instructions will come with the heat cable you buy to make the installation process as seamless as it can be.

2. Now with the heat cable attached to the hose, it’s best to insulate them both. This can either be done with insulation tubing or pipe wrap insulation. However, the easier method is going to be pipe wrap insulation as it will better bend with your water hose. Also, don’t wrap the thermostat that will be located on the heating cable.

3. Last but not least, you can buy some insulation tape to top everything off. Oh, and you’re also going to need to plug the heating cable into a power supply nearby. Heating cable runs off of electricity and when the built-in sensor detects low temperatures, the cable will start to heat.

The water hose market also has the answer

How to keep RV water hose from freezing? Why don’t you just search the internet for something that could get the job done? Guess what, you can. If you have no interest in transforming your existing RV water hose into a heated water hose, you can always just search the market for RV hoses with built-in insulation and heating prowess.

Better yet is the fact that many heated hoses on the market will be safe for drinking water. This is a very critical piece of information to look out for as you may want to use your water hose for drinking water. Another nice aspect of these types of hoses is they will naturally be very durable just due to their design. However, they’re not exactly cheap.

Quite honestly, you could probably just store your heated hose inside your RV until you need it for the winter, and just use your standard water hose during the other seasons.

How do you unfreeze an RV water hose?

What happens when this happens? How to keep RV water hose from freezing? It froze anyway. Here’s the unfortunate reality of the situation, depending on how severely cold the temperature is while you’re camping or living in your RV, your water hose may freeze no matter what.

Even the most insulated and heated of water hoses will only be able to handle so much. Plus, they can’t be too scorching hot to the point they start to melt the hoses themselves. In the case that your water hose does end up freezing, there’s a quick method you can use to unfreeze it.

  1. With the use of a heat gun, heat the hose connections for roughly 5 to 10 minutes. Thawing all sides of the connections, ensure you can unscrew the hose to get it off.
  2. Bring the hose inside your RV to allow it to warm up. You can crank up the heat if you want the process to quicken, but natural heat should be just fine.
  3. Drape the hose over your shower, just one example, to ensure that the water (after it melts) doesn’t create a mess in your RV.

Final thoughts

In reality, this issue is only going to potentially even be one for a select few of RVers. Still, whether you camp year-round or live in your RV during the winter months, all this can be problematic for you.

How to keep RV water hose from freezing? It really just comes down to providing enough heat and insulation for the hose, which can either be done yourself or by buying a special kind of water hose. However, if Mother Nature has her way, it’s not going to matter what you do as your water hose will end up freezing regardless.

Still, having the proper insulation and heat can still prevent it from freezing during most circumstances.
