Winterize RV: Blow Out Water Lines With Air

Hey guys! Are you RV enthusiasts? Do you love hitting the open road and exploring new destinations in your home on wheels? But what happens when the weather turns cold? Freezing temperatures can wreak havoc on your RV's plumbing system, leading to burst pipes and costly repairs. That's why winterizing your RV is crucial, especially if you live in an area with freezing temperatures or plan to store your RV for the winter. One of the most effective methods for winterizing your RV is by blowing out the water lines with compressed air. In this guide, we'll walk you through the process step by step, ensuring your RV's water system is protected from the harsh winter elements.

Why Blowing Out Water Lines is Essential

Before we dive into the how-to, let's talk about why blowing out your RV's water lines is so important. Water expands when it freezes. This expansion puts tremendous pressure on your RV's pipes, fittings, and water pump. If the water freezes inside these components, it can cause them to crack or burst, leading to significant water damage and expensive repairs. Blowing out the water lines removes most of the water from the system, preventing it from freezing and causing damage. Think of it as giving your RV's plumbing a good, thorough cleanse before tucking it in for the winter.

Furthermore, neglecting to winterize your RV's water system can lead to more than just burst pipes. Residual water can also damage your water heater, faucets, and even your toilet. Mold and mildew can grow in standing water, creating unpleasant odors and potentially health hazards. By taking the time to blow out your water lines, you're not just preventing freezing damage; you're also protecting your RV's overall hygiene and longevity. It's a small investment of time and effort that can save you a lot of headaches (and money) in the long run.

Finally, remember that even a small amount of water left in the system can cause problems. Low spots in your pipes or fixtures can trap water, even if you've drained the majority of the system. Blowing out the lines with compressed air ensures that these pockets of water are cleared out, providing an extra layer of protection against freezing temperatures. Consider it like this: you wouldn't leave a puddle of water sitting in your home during the winter, would you? The same principle applies to your RV. Protect your investment and ensure a worry-free RVing season by properly winterizing your water system.

Gathering Your Supplies

Okay, so you're convinced that blowing out your RV's water lines is a must. Now, let's get down to business and gather the supplies you'll need. This is like prepping your tools for a DIY project – having everything on hand will make the process smoother and more efficient. You don't want to be halfway through and realize you're missing a crucial piece! Here’s a checklist of what you’ll need:

• Air Compressor: This is the heart of the operation. You'll need an air compressor capable of delivering around 30-40 PSI (pounds per square inch). A small portable air compressor, like the ones used for inflating car tires, will usually suffice. Just make sure it has an adjustable regulator so you can control the air pressure. Too much pressure can damage your RV's plumbing system, so it's crucial to stay within the recommended range. Think of it as Goldilocks – not too much, not too little, but just right.
• Blow-Out Adapter: This adapter connects your air compressor hose to your RV's city water inlet. It's a simple but essential piece of equipment that allows you to introduce compressed air into the water lines. You can find these adapters at most RV supply stores or online. They usually have a quick-connect fitting on one end for the air compressor hose and a threaded fitting on the other end that screws into the city water inlet. It’s like the key that unlocks your RV’s plumbing system for the winterization process.
• Water Heater Bypass Kit (if applicable): Many RVs have a water heater bypass kit installed, which allows you to isolate the water heater from the rest of the plumbing system. This is important because you don't want to fill the water heater tank with antifreeze (if you choose to use it). If your RV doesn't have a bypass kit, you can usually install one yourself. It's a relatively simple DIY project that can save you time and money in the long run. Consider it a valuable upgrade for your RV's winterization toolkit.
• Non-toxic RV Antifreeze (optional): If you live in an area with extremely cold temperatures, or if you just want extra peace of mind, you can use non-toxic RV antifreeze in addition to blowing out the water lines. Antifreeze helps protect your pipes from freezing and bursting, even if some residual water remains in the system. Make sure you use non-toxic RV antifreeze, as regular automotive antifreeze is poisonous. It’s like adding an extra layer of insulation to your RV’s plumbing system.
• Basic Tools: You'll also want to have some basic tools on hand, such as a wrench, screwdriver, and pliers. These may come in handy for disconnecting hoses or fittings. It's always a good idea to have a basic toolkit with you when you're RVing, as you never know when you might need to make a quick repair. Think of it as your RVing first-aid kit – essential for handling unexpected situations.

Step-by-Step Guide to Blowing Out Your RV Water Lines

Alright, you've got your supplies gathered – great job! Now comes the main event: blowing out those water lines. Don't worry, it's not as daunting as it might sound. Just follow these steps carefully, and you'll have your RV winterized in no time. Think of it as following a recipe – each step is important for the final result.

Step 1: Drain the Water System:

This is the foundation of the whole process. You need to get as much water out of the system as possible before introducing compressed air. Start by draining your freshwater tank. Most RVs have a drain valve located near the tank. Open this valve and let the water drain completely. Be patient; this may take some time. It’s like emptying a bathtub – you want to get all the water out before you start cleaning.

Next, drain your water heater. * Make sure the water heater is turned off and the water is cool before draining it! Hot water can scald you. Locate the drain plug on the water heater and remove it. Again, let the water drain completely. Some water heaters may have a pressure relief valve that you can open to speed up the draining process. This step is crucial for preventing damage to your water heater during the winter. Think of it as giving your water heater a vacation from its hard work.

Don't forget to drain your low-point drains. These are typically located at the lowest points in your RV's plumbing system and are designed to help remove any remaining water. Open both the hot and cold low-point drains. This will help to ensure that all the water is drained from the pipes. It’s like making sure all the corners of a room are clean – you don’t want to miss any spots.

Step 2: Bypass the Water Heater (if applicable):

If your RV has a water heater bypass kit, now is the time to use it. Close the valves to isolate the water heater from the rest of the plumbing system. This prevents antifreeze from entering the water heater tank, which can be difficult to remove later. If you’re not using antifreeze, bypassing the water heater still helps to reduce the volume of air you’ll need to blow through the system. It's like taking a detour to avoid traffic – a simple step that saves time and effort.

Step 3: Connect the Air Compressor:

Now, grab your blow-out adapter and connect it to your RV's city water inlet. Then, attach your air compressor hose to the adapter. Set the air compressor regulator to 30-40 PSI. * It’s crucial not to exceed this pressure, as higher pressure can damage your RV's plumbing. * Double-check the pressure setting before you proceed. Think of it as checking the oven temperature before you bake a cake – accuracy is key.

Step 4: Blow Out the Water Lines:

Open each faucet and showerhead in your RV, one at a time, starting with the one closest to the city water inlet and moving outwards. Let the air run through each faucet until only air comes out. Don’t forget the toilet! Flush the toilet until only air blows through. This process helps to clear out any remaining water in the pipes. It’s like giving your RV’s plumbing a good workout – pushing out all the water and leaving it clean and dry.

Repeat this process several times for each faucet and fixture. This ensures that you've removed as much water as possible. You might see some water sputtering out initially, but eventually, it should be just air. Patience is key here. Think of it as brushing your teeth – you need to do it thoroughly to get the best results.

Step 5: Add Antifreeze (optional):

If you're using RV antifreeze, now is the time to add it to the system. There are a couple of ways to do this. One method is to use a water pump converter kit, which allows you to draw antifreeze directly from the bottle into the water lines. Another method is to pour antifreeze into the freshwater tank and then run the water pump to distribute it throughout the system. Follow the instructions on the antifreeze bottle for the correct amount to use.

Open each faucet and showerhead again, one at a time, until you see pink antifreeze flowing out. This indicates that the antifreeze has reached that fixture. Don't forget the toilet! Flush the toilet until you see pink antifreeze in the bowl. This step provides an extra layer of protection against freezing, especially in very cold climates. Think of it as adding a safety net to your winterization efforts.

Step 6: Don't Forget the Extras:

There are a few other areas you should address to ensure your RV is fully winterized. Pour some antifreeze down each drain (sink and shower) to protect the P-traps from freezing. These traps hold water to prevent sewer gases from entering your RV, and they can freeze and crack if not protected. Also, don't forget the ice maker and washing machine (if your RV has them). Consult your owner's manual for specific winterization instructions for these appliances. It’s like making sure you’ve covered all the bases – paying attention to the details for complete protection.
