RV Winterization Guide

When we decided to winter over in Pennsylvania this year, RV Winterization Guide with videowe knew we would have to face winterizing Aunt Glady. She is not made for sustained below freezing temperatures, so we sadly took the necessary steps to be sure she was comfortable during the winter, and that she would be ready to go in the Spring. Here are the steps we used to winterize our RV…

First and foremost, follow the instructions in your RV’s Owner Manual. We are going to share the steps that we took for you to use as a guideline. This is not a definitive list, and there will be different variables depending on your RV.

Step 1: Prepare to Winterize

At Your Last Campground…
  • Be sure to empty all tanks (grey & black).
  • Empty your hot water heater.
  • Clean your black tank. (We use a wand for the job.)
  • Turn off all propane tanks.
  • Remove all food items.
  • Remove all linens.
  • Empty the RV of any other items that you deem necessary.
  • Clean from top to bottom. Be sure to remove all evidence/smell of food.
At Your Spot for the Winter…
  • Fill tires to maximum allowed tire pressure.
  • Add any necessary pest deterrents.
  • Cover RV or if not using a cover, be sure to scrutinize the exterior and caulk/patch as needed.

Step 2: Blow Out All Water Lines

  • Start with your hot water heater lines.
  • Then, bypass your hot water heater.
  • Start with the lines closest to the city water connection and blow out each line.
  • We installed our own washer/dryer, so we also had to blow out those lines.
  • Don’t forget to blow out the low-point drain.
  • We used this air compressor.
  • We used this fitting on our air compressor.

Step 3: Add Anti-Freeze to Water Lines

  • Remove the fresh water line from the pump.
  • Install a fitting to allow you to attach a hose from the antifreeze bottle to the pump. Here is the kit we use. And the antifreeze we used.
  • Make sure all of your plumbing fixtures are closed.
  • Pump antifreeze in to the water lines.
  • Open each faucet one at a time and close it once antifreeze pours out.
  • We also drew antifreeze in to our washer/dryer water line.
  • Detach the antifreeze bottle.
  • Pour about 1 Cup of antifreeze down each drain to protect the traps.
  • Pour antifreeze in the toilet to keep the seal lubricated.

We hope this gives you a good starting point in your winterization research! And while it is sad to see Aunt Glady out in the cold, we know that we took good care of her, and she will be raring to go in the Spring!
