The last thing you want if you’re living in an RV or camping in colder climates is for your sewer hose to freeze!
Trying to dethaw frozen wastewater with a hair dryer while standing outside in freezing temperatures is not fun.
But, by taking a few simple precautions, you can greatly reduce the chances of this happening to you.
So, let’s take a look at our 3 step process to keep your RV sewer hose from freezing this winter.
Step 1: Install An Insulated RV Sideskirt
We first want to protect the underside of your RV from cold air and wind. This will essentially help protect any hoses or pipes, tanks, valves, and other RV components from freezing over.
You can buy premade RV skirts, or if you’re feeling crafty, you can make your own. If you make your own, keep in mind that some campgrounds may have regulations that your skirts must meet.

Caution: Space heaters are a great way to keep the inside of your RV warm in freezing temps. But, we do NOT recommend leaving a space heater running unattended underneath your camper to keep RV pipes from freezing while camping.
Step 2: RV Holding Tank Anti-Freeze
Once we’ve insulated the underside of the RV, we want to further reduce the chances of our holding tanks and sewer hose freezing by adding a special kind of anti-freeze to your holding tanks.
This non-toxic anti-freeze can help protect your tanks and hoses from freezing in temps down to 50 below. And it’s as simple as dumping the recommended amount down your RV toilet, shower, and sink drain.
Be sure to use the recommended amount and continually use the anti-freeze, so it doesn’t dilute past its point of effectiveness.

Step 3: Wrap Sewer Hose In Heated Coil
Lastly, it’s time to attack the problem directly by heating and insulating the sewer hose itself. So, let’s get started!
Materials Needed:
Heating & Wrapping Instructions
- Wrap the sewer hose with the heated cable, making sure the cable is tight up against the hose. You can keep the cable in place by securing it with electrical tape roughly every foot. Be sure the thermostat on the cable is in a place that will get cold enough to turn the heated cable on.
- Wrap the sewer hose with the pipe wrap insulation. Be sure to cover the hose completely with the insulation.
- Finally, completely cover the insulation with waterproof tape.
Here’s a video breakdown of how to wrap your sewer hose.
And that does it! Remember, even the best RV sewer hose is susceptible to freezing if it gets cold enough. But following the three steps outlined above is one of the best ways to ensure your sewer hose never freezes again in even the coldest climates!
