What Happens If Your RV’s Pipes Freeze?
Letting your RV’s water pipes freeze is never a good idea. Many first-time owners neglect to protect their RV if they’re storing it for the winter. It might be tempting to let it ride through the season, but repeatedly freezing the pipes will inevitably cause irreparable damage.
So, what happens if an RV’s pipes freeze?
- Frozen pipes can crack or loosen if they get too cold for too long. Water expands and contracts when it thaws and freezes, making it difficult for the pipes to keep up. Twisted or glued unions will warp and bend until they can’t anymore. This process can make them crack, leak, and need replacements.
- You won’t be able to use the water connected to any of the pipes. RV Share shows the most common symptom of frozen pipes in an RV is the water won’t flow. If it’s cold outside and nothing is coming through the pipes, they might be frozen. However, don’t forget to ensure there’s enough water in the holding tank before worrying about it.
- If the water expands, it could ruin the water pump. Water pumps have seals, gaskets, motors, and many other components that frozen temperatures can damage. If the pipes freeze and the motor keeps running dry, it’ll strip the bearings and grind until it can’t work anymore.
Frozen RV pipes are quite annoying, but they’re not too difficult to handle if you catch them early enough. The trick is to know how cold the RV’s pipes can get before they freeze. If you can keep the pipes warm enough, you’ll never have to deal with any of these problems. Read on to learn what you should do.
At What Temperature Can Motorhome Pipes Freeze?
How are you supposed to know if your RV pipes are in danger of freezing? Water freezes at 32 degrees Fahrenheit (0 degrees Celsius), but that range might not affect your pipes if they’re insulated. Nevertheless, it’s wise to prepare the pipes to freeze when the night gets too cold for too long.
RV Pipes Typically Freeze Around 32 Fahrenheit or 0° Celsius
According to RV Blogger, your RV’s pipes become much more in danger when water begins to freeze. Please turn on the water every couple of hours to ensure it’s still able to run. If it’s not coming out of the sink faucet or showerhead, it might be time to try some of the tips found in the next section. You could also use a blow dryer on medium heat.
How Quickly Do RV Pipes Freeze?
Your RV’s pipes won’t freeze the second they hit 32 degrees Fahrenheit. Instead, it might take a couple of hours for them to develop frost. If you camp in a place that dips down to 32 F for an hour at night, you likely won’t have to worry about them freezing. Low temperatures and longevity are both required to freeze your vehicle’s pipes.
As you can see, RV pipes don’t freeze too often. However, it’s best to be prepared for the worst-case scenario. If you’re worried about your RV’s pipes freezing on an upcoming trip or they’ve already gotten too cold, proceed to the next section to know how you can get them back in good condition.

While not a long-term solution, a heat gun can be useful in emergency situations when you need to thaw out frozen pipes quickly. Aim the gun at the frozen section of the pipe to gradually melt the ice and restore normal function.
Remember to exercise caution and never apply excessive heat to avoid damaging the pipes or causing a fire.
By employing these heating methods, you will be well-equipped to prevent your RV’s pipes from freezing during your camping adventures. Remember to choose the method that best suits your specific needs and preferences for optimal results.
Skirting Your RV for Winter Camping
When winter camping in your RV, skirting becomes an essential step to help prevent freezing of your pipes. Skirting helps to insulate the underside of the RV, which reduces the amount of cold air that can reach your pipes and tanks.
One option for skirting is to use thick vinyl or plastic sheeting. This material is relatively affordable and easy to install. Simply cut the sheeting to size and secure it around the base of your RV with weights or stakes. This will create a barrier against cold air, shielding your pipes from freezing temperatures.
Another option is to use foam boards, such as Styrofoam or R-Tech, for skirting. These provide more insulation than vinyl sheeting and can be cut to fit the contours of your RV. When using foam boards, secure them in place with tape, adhesive, or other fasteners. You can also add a foil face to the foam boards for extra insulation.
Inflatable RV skirting system that can be installed in minutes. Protect your RV!
Airskirting is a more advanced option, which features commercial-grade inflatable tubes that can be assembled around your RV’s perimeter. This type of skirting provides excellent insulation and durability, but may be more expensive.
Regardless of the material you choose, it is crucial to properly install your RV skirting to ensure adequate insulation and protection.
Be sure to cover the entire perimeter of your RV, closing off any gaps or openings. This will prevent drafts from sneaking under your RV and help keep your pipes from freezing during winter camping.
In addition, consider piling snow around the base of the RV once you have installed the skirting, which can further insulate and protect your pipes.
Insulate Water Tanks
Ensuring your RV’s holding tanks are protected from freezing while camping is crucial for a trouble-free and comfortable experience. Your RV has three holding tanks: fresh water, gray water (sinks + shower), and black water (toilet).
First and foremost, insulate your fresh water tank to keep it warm during colder temperatures and also cold enough to drink during hot Summers.
You can use foam board insulation, fiberglass insulation, or spray foam insulation to cover the tanks. It’s the same principles we explained to insulate your pipes.
Second, consider installing tank heaters or heating pads on your holding tanks. Electric tank heaters or heating pads can be attached directly to the bottom of the tanks, providing consistent warmth to prevent freezing.
Lastly, be prepared to take immediate action if temperatures suddenly drop. Keep a watch on the weather forecast and have plans in place to protect your holding tanks if needed. Acting promptly will help avoid potential damage and inconvenience from frozen holding tanks and pipes.
Draining and Preventing Burst Pipes
When camping in colder temperatures, it’s crucial to take measures to prevent your RV pipes from freezing. Frozen pipes can lead to cracks and eventually burst, causing extensive damage to your RV. Draining your RV’s water system is one way to minimize this risk. Here are a few tips to help you effectively drain and prevent burst pipes.
First, drain the water tanks. Emptying your holding tanks and freshwater tank will reduce the chance of water freezing inside the pipes. Make sure you do this when your RV is parked at a downward slope, helping gravity pull the water out more efficiently.
Next, protect the hot water heater by removing pressure from it and bypassing the connection. This will prevent potential damage caused by expanding frozen water inside the heater.
Check the water flow once you have done this to ensure there is no trapped water left in the pipes.
Using pipe insulation to cover exposed water lines and pipes under the RV can provide an extra layer of protection against freezing temperatures. This can be particularly useful if your RV’s freshwater lines run through the exposed underbelly.
Keeping the interior of your RV warm is another simple yet effective method to prevent pipes from freezing. A heated RV will make it harder for the cold air to reach and freeze the pipes running inside the RV’s body or floor.
In more severe freeze risks, you can also use non-toxic antifreeze to prevent water from freezing inside the pipes. Attach the antifreeze to your RV’s water system and turn on all water outlets until the antifreeze flows through.
This step can be seen as a last resort, given the hassle of flushing the antifreeze out before using the water system again.
By following these recommendations, you will greatly reduce the risk of frozen pipes, cracks, and potential bursts, ensuring your RV adventures continue smoothly even in icy conditions.
