Traditionally, winterizing a motor home, fifth wheel or any other kind of RV involves pouring four or five gallons of antifreeze into the water lines, then running the system in order to ensure that all of your pipes have antifreeze rather than water in them. This is generally effective, and not too costly.

There are, however, other efficient solutions that use less antifreeze and do a better job of keeping your water lines in tiptop shape. RV manufacturers have developed all kinds of tools and techniques for maintaining your water system. Whatever you’re in need of, we can guarantee there’s a quick fix out there!

In this quick lesson, RV expert Dave Solberg teaches you some of these alternative methods, and explains how to winterize an RV so it’s ready for the holiday season, whether you’re long-term storing or taking it out for a spin in colder climates. With his step-by-step demonstration, you’ll be able to navigate the process with no issue whatsoever.

Learning how to winterize an RV through other methods

Dave begins by walking you through the traditional method of flushing antifreeze through the lines via a basic funnel. Then he shows you how to do with these other simple but reliable ideas on how to winterize an RV:

  • 1. Buy a winterizing kit. These kits are available through a number of reputable dealers, and can be combined with an easy-to-use hand pump. All you have to do is utilize the pump and one of these aftermarket kits to pump antifreeze through the RV’s system. Once the proper amount of antifreeze is flushed into the system, Dave shows you how to open up each faucet (kitchen and all bathroom appliances (i.e. toilet, shower hose, etc.)) and let them run until you can clearly see the colored antifreeze flowing.
  • 2. Blow it out. Dave also shows you how to winterize an RV by blowing out the water system with city water. In order to do this, you’ll need to attach a small, specialized component geared toward winterizing an RV and simply run water until you see the colored antifreeze come through. Only once you can see antifreeze do you know all of the water is out of the lines. As an extra solution, some people also like to add a little antifreeze to the fresh water storage tank in order to ensure that any remaining water left over from your latest journey cannot freeze and harm the system. A cracked tank, water line or accessory part is never a good time!
