Winterizing your RV is crucial to prevent costly damage from frozen water lines. One of the most important steps is thoroughly blowing out your camper's water lines. This process removes all remaining water, preventing expansion from freezing and potential pipe bursts. This guide provides a step-by-step process, addressing common questions and concerns.
Why is Blowing Out Camper Water Lines Important?
Freezing water expands, exerting significant pressure on your RV's plumbing system. This pressure can cause pipes to crack or burst, leading to expensive repairs and potential water damage inside your camper. Blowing out your water lines with compressed air removes all the water, eliminating this risk. Ignoring this crucial step can lead to significant problems, from minor leaks to major structural damage.
What Equipment Do I Need to Blow Out My Camper Water Lines?
You'll need a few essential tools for this process:
- Air Compressor: An air compressor capable of delivering at least 90 PSI is recommended. Smaller compressors may struggle to effectively clear longer lines.
- Blow Gun: A blow gun with a nozzle that fits snugly into your water line connections is crucial. Avoid using a blow gun with too large a nozzle, as this can damage the fittings.
- Water Pressure Regulator (optional but recommended): This helps to control the air pressure and prevents damage to your system. It allows for a gentler approach to avoid accidental damage.
- RV Antifreeze (optional): While blowing out the lines is the primary method, adding RV antifreeze afterward provides an extra layer of protection.
How to Blow Out Camper Water Lines: A Step-by-Step Guide
-
Prepare Your RV: Turn off all water pumps and disconnect from any external water sources. Open all faucets and low-point drains (located at the lowest points of your water lines, often under sinks or in compartments). This allows air to flow freely through the system.
-
Connect the Air Compressor: Connect your air compressor to your blow gun. Ensure the compressor is turned off before connecting.
-
Connect to the Water System: Locate your water inlet valve (usually found near the outside of your RV). This is where you'll connect the blow gun. Some RVs require removing a filter or pressure regulator before connecting.
-
Start Blowing: Turn on your air compressor and gradually increase the pressure. You should hear air escaping from all the open faucets and low-point drains. If you notice resistance, carefully check for any blockages or closed valves.
-
Monitor the Process: Keep a close eye on the process, listening for a consistent air flow from all outlets. If air stops flowing from any particular outlet, that area might require further investigation to remove a potential clog.
-
Disconnect and Inspect: Once air flows freely from all points and you are confident all water is removed, turn off the air compressor and disconnect the blow gun. Inspect all connections for any signs of leaks or damage.
-
Add Antifreeze (Optional): For added protection, consider adding RV antifreeze to the system after blowing out the lines. This provides a further safeguard against freezing. Follow the manufacturer's instructions carefully for the appropriate amount and method of application.
How Do I Blow Out My Camper Water Heater?
Blowing out your water heater requires a slightly different approach, and often involves accessing a drain valve specifically designed for the water heater. Consult your RV's owner's manual for specific instructions, as the procedure can vary depending on the model. Incorrectly blowing out your water heater can damage its components, so carefully follow your manual's recommendations.
What if I Can't Blow Out a Specific Line?
If you encounter a line that stubbornly refuses to blow out, there might be a blockage. Try using a longer blow gun or a plumbing snake to clear the obstruction. If the problem persists, consult a professional RV technician.
How Often Should I Blow Out My Camper Water Lines?
You should blow out your camper water lines before storing your RV for the winter or any extended period when freezing temperatures are anticipated.
Can I Use a Shop Vacuum to Suck the Water Out?
While a shop vacuum can remove some water, it’s generally not recommended for thoroughly winterizing your RV's water lines. Compressed air is far more effective at removing all the water from the system and the lines' tighter spaces, reducing the risk of freezing damage.
By carefully following this guide and taking the necessary precautions, you can effectively blow out your camper water lines, ensuring your RV is protected from freezing temperatures and potential damage. Remember to always consult your RV's owner's manual for specific instructions and recommendations relevant to your model.
