Before you make the decision to purchase an RV, you need to understand that there’s a lot of work you’ll need to do to maintain it. One problem that you might run into if you take it out in the winter months is your pipes freezing. So, how cold does it need to be before your RV pipes and tanks freeze?
Unfortunately, there isn’t a definitive temperature where you start to be at high risk for pipe freezes. There isn’t a temperature where your pipes will instantly freeze. Instead, your pipes freezing is very dependant on how long they remain in the cold. However, as a general rule of thumb, you should start to take precautions once the temperature goes below the freezing temperature of 32 degrees Fahrenheit or 0 degrees Celsius.
Getting into a situation where your RV pipes freeze isn’t an ideal one. In fact, it’s a situation that can be disastrous. As a result, you should take measures to ensure that this doesn’t happen. However, to take these measures you need to know what temperatures you need to start worrying about pipe freezes.
What Temperature Will RV Water Lines Freeze?
As we mentioned above, there isn’t a definitive temperature where your RV water lines will freeze. However, you definitely need to start to worry once the temperature gets below the freezing temperature of 32 degrees Fahrenheit or 0 degrees Celsius. At this point, there is a risk that your pipes could freeze.
Once the temperature gets below the freezing temperature, if your RV stays stationary and your pipes aren’t active, they will start to cool and eventually freeze. However, the colder it is the faster it will freeze.
As a rule of thumb, you shouldn’t wait until it gets below freezing temperature to take precautions. If you wait until it gets cold, you could get into a situation where you don’t have enough time to act. As a result, you should start to prepare for the winter months once the temperature gets to around 35 degrees Fahrenheit. This will give you ample time to prepare your pipes for the winter months. This way, you won’t risk being too late and your pipes won’t freeze.
How Long Does It Take for RV Water Lines to Freeze?
When the temperature drops to below freezing temperature, you are at risk of your pipes freezing. However, they won’t freeze instantly. Instead, it takes time for things to freeze. So, how long does it take?
That question is mostly dependant on how cold it is. If the temperature drops drastically to a temperature that’s a lot below the freezing temperature, your RV pipes will freeze much quicker. However, if the temperature drops to the freezing temperature precisely, you can expect it to take roughly 24 hours for your pipes to freeze. As a result, you will need to act fast so that they don’t freeze during this time.
That being said, this timeline could be decelerated if you have taken precautions beforehand such as installing insulation or heat tape.
Will RV Holding Tanks Freeze?
The next thing you’ll probably be worried about as an RV owner is whether your RV holding tank can freeze. Unfortunately, this is something that can definitely happen if you don’t take the proper precautions. Having your holding tanks freeze can result in a significant amount of damage that can be expensive to repair, so avoiding freezes is essential.
Your risk of a holding tank freeze is very dependant on the location of your holding tank in your RV. There are certain locations where a freeze is less likely or where a freeze will be delayed. For example, if your holding tank is above the floor level, it is much more difficult for it to freeze. This is because the ambient heat that comes from your interior furnace will help delay freezing. Since heat rises, when the heater is positioned below the holding tank, the ambient heat does more to prevent the holding tank from freezing.
Conversely, if your holding tank is positioned in the underbelly of your RV, it is at a much higher risk of freezing. The heat from your heater won’t do much to prevent it from freezing and it’s much more exposed to the elements. As a result, if you have an RV with a holding tank in this position, you need to be more prepared for the winter months. If you aren’t prepared, you’ll find yourself in a situation where key parts of your RV are no longer functional because of freezing, such as your holding tank.
Can an RV Water Heater Freeze?
Another thing you might be concerned about in the winter months is your RV water heater. If it’s turned on and there’s water in it, your RV water heater will not freeze. That’s because it’s actively generating heat, making it impossible for the temperature to get cold enough for the heater to freeze. However, your RV water heater might not be turned on at all times. As a result, there’s a risk that your RV water heater could freeze while it’s turned off.
If your RV water heater freezes, you’ll be left in a situation where you no longer have access to hot water. This can be disastrous for someone who lives in an RV. You won’t be able to take showers or do a number of other things that require hot water. Not only that, but your RV water heater freezing will result in damage to the heater itself. Repairing these damages can get expensive. As a result, you should take the precautions you need to take to avoid this situation.
Tips to Prevent RV Water Lines and Tanks from Freezing
So, you should know at this point that it’s possible for pretty much everything to freeze in the right circumstances. As a result, you need to take precautions to avoid freezing from happening. There are several things you can do to reduce your risk of freezing.
If you are going to park your RV for the winter you need to winterize it. Here is a great article and video from the RV Geeks about how to winterize your RV pipes.
If you plan to camp through the winter one of the most important things to do is to install and upgrade your RV insulation. Not only will insulation protect many components of your RV from freezing, but it will also help keep the living area in your RV warm. This is something you can do that will significantly improve your quality of life during the winter months.
Furthermore, you can use heat tape on your RV pipes to help stop them from freezing. You can place heat tape on the pipes and then add foam insulation to the pipes themselves. This will lower the temperature it needs to be for them to freeze.
Another thing you can do before the winter comes is to check to make sure that your RV furnace is working properly. The last thing you’d want is for winter to come and you find out that your furnace is broken. Additionally, having your furnace on will heat up all the components of your RV and help prevent them from freezing. This includes the RV pipes and tanks.
Enjoy Your RV in the Winter by Ensuring that Your RV Pipes and Tanks Don’t Freeze
After reading, we hope you have all the information you need to ensure that your RV pipes and tanks don’t freeze when the winter comes. We know that there’s a lot of information to absorb, but all of it is important for you. With this information, you should be able to take the proper precautions so that you never run into a situation where a component of your RV is frozen.
There are several things you can do to prevent your RV pipes and tanks from freezing. Firstly, you can bolster up your insulation. This will also help keep the living area in your RV warm. You can also apply heating tape to your RV pipes directly. By using heating tape along with foam insulation, you will significantly reduce the chance of your pipes freezing. You should also make sure that your furnace is working properly. By raising the temperature of your RV, you’re obviously lowering your chances of a freeze.
With all this information you should be prepared for your next winter trip in your RV. You’ll be able to relax, enjoy the beautiful winter view, and stay warm without worry.
