How to Winterize Your Teardrop Trailer
If you have a teardrop trailer with a water system, it’s important to prepare the system for winter. As temps drop below freezing, any water that is left in the plumbing lines or in the pump will freeze and expand, potentially causing damage. This damage will present as leaks come spring.
Below, we’ve outlined the step-by-step process that you’ll need to follow to winterize your teardrop trailer water system.
What You'll Need
- 2 gallons of RV & Marine specific non-toxic antifreeze (we used Super Tech, found it at Walmart for ~$2/gallon)
- Large Funnel
- Hand-crank for leveling jack (this came with your Escapod)
- 10’ hose (this came with your Escapod)
- Optional: Driver with 19 mm bit (to use instead of the hand-crank)
- Open the output flow (left side) and run the pump until the water flow decreases to a sputter.
- Extend the leveling jack on the opposite the water output to raise the trailer, thus allowing more water flow out of the tank.
- Keep the valve open and pump on and lower the leveling jack back to its original position. At this point no water should be exiting the output nozzle.
- Close the output valve and turn off the pump.
- Open the input valve (right side) to the water tank.
- Secure one end of the hose to the input, and the other end to the funnel.
- Slowly pour the antifreeze into the funnel and keep it elevated to gravity-feed it into the tank.
- Remove the hose and close the input valve (right side).
- Open the output valve (left side) and turn on the pump until the pink liquid begins to flow out. (If it doesn't flow, just lift up the opposite side of the trailer again with the leveling jacks).
At this point the antifreeze has filled the pump and lines, and is safe to leave sitting for the duration of the freezing months!

Water Heater Winterization:
If you have the water heater upgrade on your Escapod, you’ll want to follow a few easy steps to winterize.
- Disconnect the water inlet and shower hose from the bottom of the appliance.
- Loosen the drain valve from the bottom of the water heater.
Come spring, you’ll need to sanitize the system before use. Follow these steps to ensure your water system is ready to go! As we get our rental fleet up-and-running in the spring, we’ll repost this with a video for simplicity.
De-winterizing and Sanitizing for Spring:
- Follow the 'Prep' process (outlined above) to drain as much of the antifreeze out of the tank as possible.
- Hook a water source to the input valve (right side) and fill the tank with fresh water.
- Close the input valve (right side), open the output valve (left side) and empty the entire tank.
- Gravity feed 1/4 cup of household bleach into the tank using a funnel.
- Remove funnel & reconnect to your water source.
- Fill the remaining tank with fresh water.
- Let bleach & water mixture sit for 12 hours.
- Finally, drain & flush the tank (Repeat as needed until the smell of bleach is no longer detectable in the water flow).
