Winterizing an RV with Compressed Air: A Candid Guide to Protecting Your Investment
As the crisp air settles in and the leaves begin to change, every RV owner knows it’s time to face an important seasonal task: winterizing your RV. While many folks might dread this task (I get it—it’s not exactly the funnest way to spend a Saturday), it doesn’t have to be a headache. In fact, I’d argue that learning to winterize your RV using compressed air can actually be kind of satisfying. Why? Because it means you’re protecting your investment and keeping your rig in tip-top shape for the next camping season.
In this blog post, we’ll dive into the nitty-gritty of winterizing your RV with compressed air, why it’s a recommended method, and a step-by-step guide to get it done right. So grab your favorite hot drink, buckle up, and let’s get to work.
Why Winterize?
Before we get into the details, let’s take a moment to talk about why you need to winterize your RV in the first place. RVs are exposed to the elements, and just like our houses, they can suffer damage from freezing temperatures. Nobody wants to face the wrath of a burst pipe or a ruined water heater come springtime, right?
The Risks of Not Winterizing
Frozen Pipes: Water in your plumbing system can freeze, leading to cracks and leaks. Replacing damaged pipes isn’t just a hassle; it can be a costly repair that could set you back financially.
Water Heater Damage: If the water in your water heater freezes, it can also cause significant damage. A new water heater isn’t cheap, and who wants that headache?
Mold and Mildew: In addition to the plumbing issues, failing to winterize properly can lead to moisture build-up, creating the perfect breeding ground for mold and mildew. Trust me, no one wants to deal with that nasty cleanup.
General Wear and Tear: Winter can be brutal on an RV, causing wear on the exterior, tires, and more. Proper winterization can help mitigate this damage.
With all that in mind, let’s get down to the business of how to winterize your RV using compressed air!
What You’ll Need
Before you dive in, make sure you’ve got your supplies ready. Here’s a handy list of what you’ll need for this winterizing task:
1. Compressed Air Source: This could be a portable air compressor, an air tank, or access to an air pump.
2. Air Pressure Regulator: This helps to control the pressure of the air going into your system, so you don’t accidentally overdo it.
3. Blow-Out Plug: This allows you to connect your compressed air source to your RV’s water system. It typically goes in the city water connector. You can find a blow-out plug at most RV supply stores.
4. Basic Tools: Such as pliers, wrenches, and screwdrivers.
5. RV Antifreeze (if you choose to go that route for your drains, though we’re focusing on compressed air here).
6. Buckets or towels to catch any residual water.
Step-by-Step Guide to Winterizing with Compressed Air
Now that you’re geared up, let’s break down the winterizing process into simple steps.
Step 1: Prepare Your RV
First things first—make sure your RV is clean and dry. You don’t want any residual moisture hanging around because it can lead to problems later on.
1. Empty Your Tanks: Drain your fresh water tank, sewage tank, and gray water tank. This eliminates moisture that could freeze and damage your systems.
2. Remove Filters: Take out any water filters to prevent them from freezing or clogging.
Step 2: Disconnect and Drain
Now let’s get down to business draining your plumbing system:
1. Find Your Drain Valves: Locate and open the low point drain valves for your plumbing. You’ll find them under the RV—these will allow any remaining water to escape.
2. Open All Faucets: Turn on all your faucets and make sure they’re in the open position (including sinks, showers, and outside showers). This will help water evacuate from your lines.
Step 3: The Blow-Out Time
Here’s where the magic happens!
1. Attach the Blow-Out Plug: Take your blow-out plug and insert it into the city water inlet. Make sure it’s snug to prevent air leaks.
2. Set the Compressor: Set the air compressor to around 30-40 psi (pounds per square inch). Using an air pressure regulator is critical here—this prevents the air from being too forceful and damaging the plumbing.
3. Blow Out the Lines: Turn on the air compressor and let it run. You should see air bubbles coming from your opened faucets. This indicates that water is being pushed through the lines—you’ll want to see some bursts of water coming out and hear some air whooshing.
4. Move to Each Faucet: One by one, visit each faucet (inside and outside), and repeat the process until you don’t see any more water coming out. Don’t forget the toilet—flush it to clear out any residual water in the bowl and lines.
5. Check the Water Heater: If you can drain your water heater, make sure to do this before applying air pressure to it. The tank should be cold and empty before you proceed.
Step 4: Add Antifreeze (Optional)
If you want to take an extra step (especially for your toilet and the drains), adding a bit of RV antifreeze can be wise.
1. Pour Antifreeze: After you’ve blown out the lines, pour some RV antifreeze into the toilet and sink drains to protect those p-traps from freezing.
2. Flush the Toilet: Add antifreeze in the toilet bowl so it stays safe from freezing.
Step 5: Final Checks
Before you tuck your RV away for the winter, give it a final once-over:
1. Inspect the Exterior: Check for any cracks or areas that need sealing. It’s far easier to fix these now than when spring rolls around.
2. Remove Any Perishables: Empty the fridge and cupboards of food items that could go bad over the winter.
3. Check Tires and Battery: Don’t forget to inflate your tires to the correct pressure and disconnect your battery or place it on a trickle charger.
Step 6: Storage
Now that your RV is winterized, it’s time to store it properly. Choose a dry, shaded location if possible. If you can, invest in an RV cover to protect it from snow, ice, and other elements.
Tips and Tricks for Success
Check with the Owner’s Manual: Your RV’s owner’s manual may have specific recommendations or procedures for winterizing.
Stay Organized: Create a checklist so you can easily track what has been completed.
Have a Buddy: If you can, tackle this task with a friend. It’s always easier (and more fun) with two sets of hands!
Consider Professional Help: If this process feels overwhelming, don’t hesitate to reach out to a professional to winterize your RV. It’s better to be safe than sorry!
