DEWINTERIZING YOUR TRAVEL TRAILER: A SIMPLE 4-STEP SPRING GUIDE

Dewinterizing your travel trailer (RV) is an essential step to kick off your camping season. The good news? It’s much easier than you think.

Here’s a complete, step-by-step guide to get your trailer ready quickly and stress-free.


STEP 1 – CONNECT YOUR TRAVEL TRAILER (RV)

Before anything else, make sure your trailer is properly connected to essential services.

To do:

  • Connect water to the city water inlet
  • Plug in electricity (30A or 50A depending on your unit)
  • Connect the sewer hose
  • Open slide-outs, if applicable

👉 Tip: This step is ideal if you’re at a campground or at home with full hookups.


STEP 2 – FLUSH OUT THE ANTIFREEZE FROM THE PLUMBING

During winter, RV antifreeze (pink liquid) protects your pipes. Now it’s time to remove it completely.

Procedure:

  • Open all faucets (kitchen, bathroom, shower)
  • Let water run until the pink liquid is completely gone
  • Run cold water first, then hot water
  • Flush the toilet to remove antifreeze from the system

No access to running water?

  • Fill the fresh water tank
  • Turn on the water pump
  • Set the pump valve to summer mode


STEP 3 – OPEN THE LOW POINT DRAINS

Low point drains allow you to fully empty the plumbing system.

To do:

  • Locate the low point drains under your trailer
  • Open both valves (hot and cold water)
  • Let water run until no antifreeze remains
  • Close the valves

👉 Recommended: Check for leaks after closing the valves.


STEP 4 – REACTIVATE THE WATER HEATER

The water heater is usually bypassed during winter. It must be set back to normal operation.

⚠️ For tankless water heaters, skip this step

Procedure:

  • Locate the valves (typically 1 to 3 depending on the model)
  • Set them back to summer mode
  • Reinstall the drain plug or anode rod (very important)

⚠️ Never turn on the water heater without water inside — this can cause serious damage.


IMPORTANT ADDITIONAL TIPS

For a complete and safe RV spring opening, also:

  • Remove protective covers (AC unit, water heater vent, etc.)
  • Check seals and caulking
  • Inspect tires (pressure and wear)
  • Test all appliances (fridge, furnace, air conditioner)
  • Sanitize the fresh water system (recommended at the start of the season)

CONCLUSION

Dewinterizing your travel trailer is a quick and essential step to fully enjoy the camping season. By following these simple steps, you’ll ensure a smooth start and extend the life of your RV.
