Winterizing your RV is crucial to prevent costly damage from frozen water lines. One of the most effective methods is blowing out your camper water lines with compressed air. This process removes all water from the system, eliminating the risk of freezing and bursting pipes. This comprehensive guide will walk you through the process, answer common questions, and help you protect your RV plumbing investment.
Why Blowing Out Water Lines is Essential for RVs
Freezing water expands, and this expansion exerts tremendous pressure on your RV's plumbing system. The result? Burst pipes, leaks, and costly repairs. Blowing out your water lines removes the water entirely, preventing this damage. This is especially important for those storing their RVs in freezing temperatures during the winter months. Unlike using antifreeze, this method doesn't leave behind any residue that could affect your system in the spring.
How to Blow Out Camper Water Lines: A Step-by-Step Guide
Tools You'll Need:
- Air compressor: Choose one with a minimum of 100 PSI. A higher PSI might be needed depending on the length and complexity of your RV's water lines.
- Air chuck: This connects your air compressor to the water lines.
- Blow gun: Use a blow gun with a long, narrow nozzle for better access to your lines. Ensure it's clean to avoid contaminating your system.
- Water pressure regulator: This ensures the pressure remains below the maximum safe pressure for your system.
- Low pressure air hose (Optional but recommended) - Protects delicate plumbing from damage caused by too much pressure.
Steps:
- Turn off water sources: Ensure all water pumps and city water hookups are turned off.
- Drain the water heater: Completely drain your water heater tank following the manufacturer's instructions.
- Open all faucets: Open all faucets, both hot and cold, throughout your RV.
- Open low-point drains: Locate and open all low-point drains. These are usually located under sinks and in other low points of your plumbing system.
- Connect the air compressor: Connect the air chuck to the city water hookup. It is vital you use a pressure regulator to avoid damaging the lines.
- Slowly introduce air: Slowly turn on the air compressor, monitoring the pressure gauge closely. Avoid exceeding the maximum safe pressure for your RV's plumbing system.
- Listen for changes: Listen carefully for changes in the air flow as the water is pushed out of the system. You'll notice a difference as the air replaces the water.
- Disconnect the air compressor: Once the air flows freely and consistently, disconnect the air compressor.
- Check for leaks: After disconnecting, carefully inspect all connections and pipes for any leaks.
Frequently Asked Questions (FAQ)
What PSI should I use to blow out my camper water lines?
The ideal PSI varies depending on your RV's plumbing system. Consult your owner's manual for recommendations. A general guideline is to start low and gradually increase pressure while carefully monitoring for leaks. Never exceed the maximum pressure rating of your system.
Can I use a shop vac to suck the water out instead?
While you can use a shop vac to help remove water, it is not as effective as compressed air for removing all traces of water from the system, leaving more room for the possibility of freezing. Compressed air is the preferred method for complete water removal.
What if I don't have access to an air compressor?
If you don't have access to an air compressor, you can use RV antifreeze to winterize your system. This involves adding antifreeze to all faucets, toilets, and other water lines. Remember to follow the manufacturer's instructions carefully.
How often should I blow out my RV water lines?
You should blow out your RV water lines before storing your RV for extended periods in freezing temperatures. For those living full-time in their RV in colder climates, it is a good idea to routinely drain your water tank and leave your faucets open to prevent damage from freezing temperatures.
What if I accidentally damage my water lines while blowing them out?
If you accidentally damage your water lines while blowing them out, immediately stop the process and contact a qualified RV technician for repair. Attempting to repair the damage yourself may cause further problems.
By following these steps and addressing common concerns, you can effectively blow out your camper water lines, protecting your RV from the potentially damaging effects of freezing temperatures. Remember, prevention is always better than a costly repair!
