It’s nearly that time of the year again! When the weather gets cold, it either means storing your RV until next spring or swapping to your winter outfits and winter sports equipment. But the real work comes down to winterizing your RV. In the next section, you will be learning how to winterize RV without antifreeze.
People often ask: “Do I need to winterize my RV even when plugged in?” Whether your RV will be dormant or plugged in, you need to begin winterizing your RV when the temperature drops. The reason why you winterize your RV is to protect your pipes, tanks, and water heaters from freezing or, worse, bursting!
Now, the next question is: “How do I know it’s starting to get too cold?” When the temperature hits below 32 degrees Fahrenheit or 0 degrees Celsius, it’s time to start winterizing. For information, read on!

What Tools Will You Need for Winterizing RV without Antifreeze
Since we plan to winterize a camper without antifreeze, we should prepare all these tools instead.
- Standard tool kit: A common or household tool kit will do. You need to include a wrench set and socket wrenches as there may be some bolts that you will need to let loose. You will also need a screwdriver because it will help you get into the water valves.
- Air compressor: An air compressor is an essential tool you will need; make sure it is at least 50 PSI. This tool will help you completely empty your pipes of water.
- Blow out adapter: It is also known as a blowout plug, and it is plugged into the air compressor. This will be plugged into the RV’s water lines’ adapter to clear out any liquid.
- Water hose: A water hose is essential for you to flush out your tanks and other plumbing lines. Do NOT connect or use the hose that you will be using for your freshwater tanks. This water hose is ONLY dedicated to cleaning your waste tanks.
Now We are Ready to Begin Winterizing!
Step 1: Drain the Systems
- You will need to drain your water tanks by locating the main water drain, otherwise known as a petcock. This part is normally found under the vehicle and will be connected to the water tanks. It would be best that your vehicle is at an angle where the petcock is to quickly drain the water.
- Remove the petcock by utilizing a wrench and let the water drain.
- Inside the trailer, turn on all your plumbing, faucets, hose and flush the toilet for all the water to empty the lines. Allow the faucets to run until finished.
- You will need to begin by emptying your black holding tank. Connect these tanks to the dump station connectors; these will be marked. You will need to begin with the black tank first because it is connected to the waste from your toilet.
- Next, you will need to do the same thing for the gray water tank. It is suggested to do this after emptying the black tank since the grey tank has soapy water to wash the lines and remaining wastes.
- Lastly, you will need to empty and clean the freshwater tank.
Step 2: Attach the Air Compressor to your Water Lines
- Begin by setting up your air compressor and attaching the blow-out plug to its air hose. You will then plug into the trailer’s water inlet. To avoid damaging your water lines, you should adjust the air compressor to less than 30 PSI or a maximum of 50 PSI. If you go beyond, it might cause damage to your plumbings seals and cause other issues down the line.
- You will need to keep the air compressor on with the 30 seconds intervals and stopping for a few seconds until there is no more water. This will prevent overwhelming the pipes and is also great in extracting any obstruction in the water system.
Step 3: Closing up shop
- Once you’ve finished, close all the valves. Before you replace the petcock, it would be best that you would envelop the threading with Teflon tape to create a seal. Be mindful not to tighten it too much as it would later create issues with the threading causing it to strip and possibly leak.
- Do not also forget to turn off all the indoor plumbing. There may still be water residue within the lines. Nevertheless, there shouldn’t be sufficient liquid that would cause the pipes to fracture when the temperatures drop in the middle of winter.
