Disclaimer: This article is meant to provide an overview of the RV de-winterization process. If you do not feel completely comfortable performing the steps in this process, we recommend having a certified technician at a service center or dealership properly de-winterize your RV.
Those chilly, bleak days of winter have now passed, and the warmer weather is quickly approaching; you’re probably itching to get out and enjoy the sunshine. But in order to enjoy the upcoming shorts weather, you need to properly prepare your RV so you can savor the joys of RVing rather than fixing problems. In this article, we'll provide a brief overview of the de-winterization process and some additional de-winterization tips to avoid annoying issues in the midst of a camping trip.
If your RV was properly winterized when you put it away for the winter, the process of de-winterization should be pretty smooth and relatively easy, since it’s essentially the reverse of the winterization process. However, if you don't feel completely confident personally de-winterizing your unit or are unsure of any of the steps below, it’s probably best to have a certified professional complete the process for you.
That being said, even if you choose to have your RV professionally de-winterized, it’s still helpful to understand the process. Conveniently, the de-winterization steps for almost every RV class or type are nearly the same; there still may be some processes that will vary slightly on certain units, so it’s important to check your RV’s user manual for instructions about de-winterizing your specific unit before taking the following process as gospel.
The de-winterization process and RV checks may require the use of certain tools and products that you may need to purchase to complete all the steps.
De-winterizing your RV means following several different procedures and checklists to complete the overall process. The first and arguably most important process is clearing your water lines of antifreeze. Before starting this process, you’ll need to make sure you can access the front and back of your water heater. The front of the water heater is always located on the outside of the RV and is the access point for checking the anode rod and inspecting the overall heating system for damage. The back of the water heater is located somewhere inside the RV; some are located inside a closet or somewhere near the stove, but there are others that are hidden behind a drawer or some panelling. This is where you will turn the water heater bypass on and off.
The step order for doing this might be slightly different if, when winterizing, you decided to bypass the water heater and not fill it with antifreeze. In this case, you can access and inspect the anode rod and drain caps before flushing the system, but if you did add antifreeze to the water heater, flush the system before inspection.
Congratulations! You’ve completed the de-winterization process for your RV’s water system. But you’re not done quite yet! There are a few additional checks to be sure your RV is completely ready for the summer fun you have planned.
There are some things you should inspect and test to make sure everything is in proper working order. After all, you wouldn't want to get to your campsite and find that your stove isn't working or you have a leak in the roof when a freak rainstorm hits.
Note: Again, if maintenance on any of these items is something you are not comfortable with, take your RV to a professional.
Before you hit the road for another summer of fun in the sun, we recommend doing a deep clean of both your black water and gray water holding tanks. We always suggest that you perform a deep cleaning on your holding tanks twice per year, once at the beginning of the RVing season and once at the end before you winterize. So if you didn’t do a deep clean before you winterized your camper, it’s definitely a great idea to perform a deep clean on both tanks when you de-winterize. We recommend using Unique Tank Cleaner to deep clean your black tanks because the concentration of bacteria and enzymes swiftly breaks up any residual waste that is stuck to the floor, walls, or sensors of your black tank. We recommend using Dawn Ultra to perform a deep cleaning on your gray tanks because it is a fantastic grease-eater and will also not damage the good bacteria you may be adding to your gray tank. For step-by-step instructions on deep cleaning your tanks, refer to our guide on Deep Cleaning RV Wastewater Holding Tanks.
