After you make the decision to purchase an RV, there is a lot of equipment that you’ll need to familiarize yourself with. One of those pieces of equipment is the RV water hose. An RV water hose is a hose that runs from a campground water spigot to your RV. It looks like your typical garden hose, so you should be able to identify it easily. The RV water hose connects from the campground spigot to the RV city water connection on the RV. This is the location where you screw in the hose.

Once you’re familiar with the RV water hose, one of the first things you need to do is learn how to keep it from freezing. When you’re traveling in your RV, there’s a good chance the nights will get very cold. This obviously isn’t true at all times of the year, but if you plan on traveling during the fall and winter, this is something you need to consider. If you fail to keep the RV water hose from freezing, you’ll run into some serious issues.

So, how do you keep an RV water hose from freezing? To keep you’re your RV water hose from freezing, you should insulate your hose. You can do this by wrapping it in a heat tape. Make sure the entire hose is covered so that it remains insulated. You can also keep it from freezing by keeping your faucet running. It’s harder for moving water to freeze, so keeping your faucet running means that a colder temperature will be required to freeze your hose.

What Temperature Will RV Water Lines Freeze?

Your RV water lines can start to freeze once it gets to 32 degrees Fahrenheit or 0 degrees Celsius. That’s the freezing temperature, so it’s possible for water to freeze at that point. However, water isn’t going to instantly freeze the second it reaches the freezing temperature. If the temperature is hovering around the freezing temperature, it will take awhile for the water to reach the point where its fully frozen. As a result, if you’re using water fairly regularly and keeping your water moving, there isn’t a high risk of water freezing at the freezing temperature.

The colder it gets the more you need to worry about your RV water hose freezing. That’s because the colder it gets, the less time it’s going to take for water to freeze. So, if it’s 0 degrees Fahrenheit, it isn’t going to take long for your RV water hose to freeze.

How to Unfreeze an RV Water Hose?

How to Unfreeze an RV Water Hose?

Sometimes there isn’t anything you can do and it’s simply too cold to keep your hose from freezing. In this situation, you still need water, so you need to unfreeze your RV water hose.

To unfreeze your RV water hose, the first thing you should do is use a heat gun on the hose connections. You should heat the connections points for 5 to 10 minutes. Make sure you move the gun to all sides of the connection so that it thaws on all sides.

Once you’ve thawed the connection point, you can unscrew the hose from the ports on your RV and water supply. Once it’s unscrewed, bring the hose inside for it to warm up. You can turn up the heat in your RV to speed up the process, but if you’re patient that isn’t necessary. It’s a good idea to drape the hose in your shower so that as it unfreezes the excess water doesn’t create a mess.

Once it’s unfrozen, check the hose for damage before reattaching it. Freezing can cause damage because water expands when it’s frozen. As a result, there is a chance that your hose could have burst, popped, or stretched in certain areas. If there isn’t any damage, you can reattach it. However, if there is damage, you’ll need to purchase a new hose.

How Do I Heat My RV Water Hose?

One of the best ways to heat your RV water hose is with heat cable. To do this properly you’ll need to measure the length of your hose so that you know how much cable you’ll need. You should then tape the heat cable to the hose with electrical tape every foot along the hose. Heat cable detects the temperature of the hose and will heat it up if it gets cold. As a result, you want several points where the cable is making direct contact with the hose.

Once you’ve applied the heat cable, you should cover the hose and heat cable with foam insulation tubes. These tubes will help keep the hose warm and insulated. You should then wrap the foam with pipe insulation tape.

You can then plug the heat cable into a power supply to turn it on. The heat cable will then start heating your hose. Finally, connect the hose to the water supply and your RV’s pump. It will then work as it normally would in warm weather.

You also need to check more frequently to ensure that you hose doesn’t freeze. Since these hoses are exposed to elements more, there is a higher chance that they freeze.
