Bypass the Water Heater

To prevent your water heater from filling up with antifreeze, you'll need to bypass it. If your travel trailer has a built-in water heater bypass kit, follow the manufacturer's instructions. If not, you may need to install an aftermarket bypass kit.

Blow Out the Water Lines

Blowing out the water lines is an effective way to remove any remaining water from the system.

Here's how:

• Connect an air compressor or hand pump to the city water inlet of your travel trailer.

• Set the pressure to around 30-40 psi (pounds per square inch).

• Open each faucet one by one, starting from the highest point and working your way down. This includes the kitchen sink, bathroom sink, shower, and toilet.

• Repeat this process until only air is coming out of the faucets.

Add Antifreeze to the System

Now that the water lines are clear, it's time to add antifreeze to protect against any residual water freezing.

Follow these steps:

• Pour RV antifreeze into a bucket or catch basin.

• Use a hand pump or the water pump in your travel trailer to pump the antifreeze through the system.

• Start with the furthest faucet from the water pump and work your way towards it, opening each faucet one at a time until pink-colored antifreeze flows out.

• Flush the toilet until antifreeze appears in the bowl.

• Don't forget to pour antifreeze down each drain to protect the traps.

Additional Tips and Considerations

• Ensure that your RV water filter is bypassed during the winterization process, as the antifreeze can damage the filter.
