Winterize RV: Blow Out Water Lines Guide
Winterizing your RV is crucial to prevent damage from freezing temperatures, especially to your water lines. One of the most effective methods is blowing out the water lines with compressed air. This guide will walk you through the process, ensuring your RV is protected during the cold months.
Why Winterize Your RV?
Winterizing your RV is essential for preventing costly damage caused by freezing water. When water freezes, it expands, and this expansion can crack pipes, damage plumbing fixtures, and even ruin your RV's water heater. Proper winterization ensures that all water is removed from the system, safeguarding it from freezing temperatures. Think of it like this, guys: leaving water in your lines during winter is like leaving a ticking time bomb. The cost of repairs from burst pipes can be significant, far outweighing the time and effort spent on winterizing. Plus, nobody wants to start their RV season with a major plumbing disaster!
Protecting your RV's plumbing system involves more than just draining the tanks. Residual water can remain in the lines, P-traps, and even the water pump. Blowing out the lines with compressed air is a highly effective way to ensure that this residual water is cleared out. Ignoring this step can lead to cracked pipes and fittings, which can be a real headache to fix. Beyond the plumbing, winterizing also involves protecting other components like the water heater and appliances that use water. Freezing temperatures can wreak havoc on these systems, so it's best to take a comprehensive approach to winterization. By taking the time to properly winterize, you’re not just protecting your investment; you're also ensuring that your RV is ready for your next adventure when warmer weather arrives.
Avoiding costly repairs is the primary goal of winterizing your RV. Freezing temperatures can cause water to expand, leading to burst pipes, damaged fixtures, and even a cracked water heater. The cost of repairing these damages can easily run into the thousands of dollars. By comparison, the cost of winterizing your RV – whether you do it yourself or hire a professional – is relatively minimal. Blowing out the water lines with compressed air is a key step in preventing these issues. This process ensures that virtually all water is removed from the plumbing system, minimizing the risk of freezing. Additionally, remember that insurance policies may not cover damage caused by freezing if the RV wasn't properly winterized. So, in the long run, winterizing is not just a matter of convenience; it's a financially sound decision that can save you a lot of money and stress.
Tools and Materials You'll Need
Before you begin, gather all the necessary tools and materials. Having everything on hand will make the process smoother and more efficient.
Essential tools and materials for blowing out your RV water lines include an air compressor, a blow-out adapter, and some basic plumbing tools. An air compressor is the heart of this process, providing the compressed air needed to push water out of the lines. You'll want a compressor that can deliver around 30-40 PSI (pounds per square inch), which is a safe pressure for RV plumbing systems. A higher pressure could damage your pipes and fittings. The blow-out adapter connects the air compressor hose to your RV's city water inlet. These adapters are readily available at most RV supply stores and are designed to create a secure, airtight connection. In addition to these essentials, you might need a few basic plumbing tools like wrenches and screwdrivers to access and manipulate certain valves and fittings. Having these tools handy can save you time and frustration during the winterization process. Don't forget a roll of Teflon tape too – it's useful for ensuring tight seals on threaded connections and preventing leaks.
An air compressor is the most important tool in this process, as it provides the necessary air pressure to clear the water lines. The ideal compressor should be capable of delivering a consistent air pressure of 30-40 PSI. This pressure range is sufficient to remove water without risking damage to your RV's plumbing system. Using too much pressure can cause pipes to burst or fittings to crack, so it's crucial to monitor the pressure gauge on your compressor. Smaller, portable air compressors are generally suitable for RV winterization, but make sure it has enough capacity to complete the job without overheating. If you're considering purchasing a compressor, look for models specifically designed for RV use, as they often come with the necessary adapters and features. Alternatively, you might be able to rent an air compressor from a local hardware store, which can be a cost-effective option if you only need it for this one task. Whatever compressor you choose, ensure it's in good working condition and that you understand how to operate it safely.
A blow-out adapter is a simple but crucial fitting that connects your air compressor to the RV's water system. This adapter typically screws onto the city water inlet of your RV, providing a secure and airtight connection for the air hose. Blow-out adapters are usually made of brass or plastic and are designed to withstand the pressure from the air compressor. When selecting a blow-out adapter, make sure it matches the thread size of your RV's city water inlet to ensure a proper fit. Using the wrong adapter can lead to leaks and reduce the effectiveness of the winterization process. Some adapters come with a built-in pressure regulator, which can help you control the amount of air pressure entering the system and prevent damage. These adapters are particularly useful if your air compressor doesn't have a regulator or if you want an extra layer of protection. You can find blow-out adapters at most RV supply stores or online retailers. They're an inexpensive but essential tool for properly winterizing your RV's water lines.
Step-by-Step Guide to Blowing Out Water Lines
Follow these steps carefully to ensure your RV's water lines are properly cleared of water.
Draining the water tanks is the first crucial step in the winterization process. Start by draining both the fresh water tank and the water heater. For the fresh water tank, locate the drain valve – usually a small spigot at the bottom of the tank – and open it to allow the water to flow out. Make sure you have a suitable container or drainage area to collect the water. For the water heater, turn off the power to the heater (both electric and gas) and let the water cool down to avoid scalding yourself. Then, remove the drain plug or anode rod (if equipped) to drain the water. It's a good idea to flush the water heater tank to remove any sediment that may have accumulated. You can do this by using a tank flushing wand or a similar tool. Once both tanks are completely drained, replace the drain plug on the water heater and close the fresh water tank drain valve. Remember, draining the tanks is just the beginning; you still need to clear the water lines to prevent freezing damage.
Bypassing the water heater is an important step to prevent filling the water heater tank with antifreeze or compressed air. Most RVs are equipped with a bypass valve system for the water heater, which allows you to isolate the tank from the rest of the plumbing system. Locate the bypass valves, which are typically located near the water heater itself. There are usually three valves involved: one on the cold water inlet, one on the hot water outlet, and one bypass valve that connects the inlet and outlet lines. To bypass the water heater, you'll need to close the inlet and outlet valves and open the bypass valve. This configuration allows water or air to flow through the plumbing system without entering the water heater tank. If your RV doesn't have a bypass valve system, you may need to install one. This is a relatively simple DIY project that can save you time and money in the long run. Bypassing the water heater not only protects it from damage but also reduces the amount of antifreeze needed to winterize the system, as you won't be filling the tank. Make sure you understand how your specific bypass system works before proceeding with the winterization process.
Connecting the air compressor to the city water inlet is the next step in blowing out the water lines. First, ensure that your air compressor is set to a pressure of 30-40 PSI. Higher pressure can damage your RV's plumbing. Attach the blow-out adapter to the air compressor hose. Then, screw the blow-out adapter onto your RV's city water inlet. Make sure the connection is secure and airtight to prevent any air leaks. Once the adapter is connected, slowly turn on the air compressor and let it build up pressure in the system. You should be able to hear the air flowing through the pipes as it begins to push water out. It's a good idea to wear safety glasses during this process to protect your eyes from any water or debris that may be expelled from the lines. Regularly check the pressure gauge on the compressor to ensure it stays within the recommended range. With the air compressor connected, you're now ready to start blowing out the individual water lines and fixtures in your RV.
Opening faucets and fixtures one at a time is the key to effectively blowing out the water lines. Start by opening the faucets farthest from the city water inlet, typically the bathroom and kitchen faucets. Open both the hot and cold water taps to allow air to flow through both lines. You'll likely see water sputtering out initially, followed by a steady stream of air. Let the air run through each faucet until no more water comes out and only air is flowing. This may take a few minutes for each fixture. Next, move on to the shower, toilet, and any other water-using appliances or fixtures in your RV. Don't forget to flush the toilet several times to clear any water from the bowl and lines. It's important to open and close each fixture individually to ensure that all water is expelled from the system. Work your way systematically through the RV, from the farthest to the closest fixtures, to ensure a thorough blow-out. Once you've gone through all the faucets and fixtures, you can move on to the next step.
Don't forget the low point drains! These are essential for removing water that may have settled in the lowest parts of your plumbing system. Locate the low point drains, which are usually small spigots or valves positioned underneath the RV, often near the water tank or water pump. There are typically two low point drains: one for the hot water line and one for the cold water line. Place a container under each drain to catch any water that comes out. Open the drains and allow any remaining water to flow out. You may notice that water continues to trickle out even after you've blown out the faucets and fixtures. This is normal, as the low point drains are designed to catch water that settles in the low spots. Leave the drains open while you blow out the rest of the system to ensure complete drainage. Once you're satisfied that no more water is coming out, you can close the low point drains. For extra protection, you can also pour a small amount of RV antifreeze down the drains to prevent any residual water from freezing.
Additional Tips for Winterizing Your RV
Beyond blowing out the water lines, there are other steps you can take to fully winterize your RV.
Adding RV antifreeze to the P-traps and toilet bowl is a crucial step to prevent freezing and damage. P-traps are the curved sections of pipe under sinks and showers that hold water to prevent sewer gases from entering the RV. Pouring RV antifreeze into these traps displaces the water, protecting them from cracking in freezing temperatures. Similarly, adding antifreeze to the toilet bowl and flushing it ensures that the toilet plumbing is protected. Use RV antifreeze specifically, as it is non-toxic and safe for plumbing systems. Never use automotive antifreeze, as it is highly toxic and can damage your RV's plumbing. Pour a cup or two of RV antifreeze into each P-trap and about a quart into the toilet bowl. Flush the toilet a few times to distribute the antifreeze throughout the system. This simple step can prevent costly repairs and ensure that your RV is ready for use in the spring. Remember, guys, a little bit of antifreeze can go a long way in protecting your plumbing!
Disconnecting and draining hoses is an often-overlooked but essential part of winterizing your RV. Any hoses connected to your RV, such as the fresh water hose and the sewer hose, can retain water that can freeze and cause damage. Disconnect these hoses from your RV and drain any remaining water from them. Store the hoses in a warm, dry place to prevent them from freezing and cracking. For the fresh water hose, you can blow it out with compressed air to ensure it's completely empty. For the sewer hose, make sure to rinse it thoroughly before storing it to remove any residual waste. Properly storing your hoses will not only protect them from freezing but also prolong their lifespan. It's a small step that can save you the hassle and expense of replacing damaged hoses in the spring. So, take a few extra minutes to disconnect and drain your hoses – it's well worth the effort!
Inspecting seals and openings is a critical step in preparing your RV for winter storage. Look for any gaps or cracks around windows, doors, and other openings where cold air and moisture can enter. Seal these openings with caulk or weather stripping to prevent drafts and reduce the risk of freezing. Inspect the roof for any signs of damage or leaks and repair them promptly. Water intrusion can lead to significant problems, including mold and structural damage. Check the seals around vents and skylights as well, as these are common areas for leaks. By thoroughly inspecting and sealing your RV, you can create a more protected environment inside, which will help prevent freezing and other winter-related issues. This proactive approach can save you from costly repairs and ensure your RV stays in good condition throughout the winter months. Remember, a well-sealed RV is a happy RV!
