What Pressure to Blow Out RV Water Lines

One of the most important tasks in preparing your RV for winter storage is blowing out the water lines. This process helps prevent any remaining water from freezing and causing damage to the plumbing system. However, it is crucial to use the correct pressure when blowing out your RV’s water lines to ensure a safe and effective winterization. In this article, we will discuss the ideal pressure to use and provide some useful tips for blowing out your RV water lines.

The Ideal Pressure

The ideal pressure for blowing out RV water lines is around 30-40 PSI (pounds per square inch). This range provides enough force to remove the water from the lines without causing any damage. It is important to avoid using excessive pressure as it can lead to bursts or leaks in the plumbing system.

To achieve the desired pressure, you will need an air compressor with a pressure regulator. This tool allows you to set the pressure to the recommended range and ensures a controlled and safe blowing out process. Additionally, it is essential to use an air compressor with a tank capacity suitable for your RV’s water system.

Tips for Blowing Out RV Water Lines

Now that we know the ideal pressure to use, let’s discuss some tips for effectively blowing out your RV water lines:

  • Drain the water system: Before blowing out the lines, make sure to drain all the water from your RV’s plumbing system. This includes draining the fresh water tank, hot water heater, and all faucets and drains.
  • Disconnect and bypass the water heater: To prevent any damage to your water heater, ensure it is disconnected and bypassed during the blowing out process. This step is crucial as the water heater can retain water even when the rest of the system is drained.
  • Open all faucets and valves: Once the water system is drained and the water heater is bypassed, open all faucets, showerheads, and valves in your RV. This step allows the compressed air to flow through the entire system and push out any remaining water.
  • Blow out the water lines: Attach the air compressor to the RV’s water system using a blowout plug or the city water inlet. Set the pressure to the recommended range (30-40 PSI) and slowly introduce the compressed air into the system. Start with the faucet furthest from the compressor and work your way through each faucet and valve until you reach the one closest to the compressor. Hold each open for about 30 seconds to ensure all the water is blown out.
  • Check for any leaks: After blowing out the water lines, inspect all faucets, valves, and connections for any signs of leaks. If you notice any leaks, tighten the fittings or replace any damaged components. It is essential to fix any leaks before storing your RV for winter.
  • Add antifreeze: In addition to blowing out the water lines, it is recommended to add antifreeze to the plumbing system to provide extra protection against freezing temperatures. Follow the manufacturer’s instructions to properly add antifreeze to your RV’s water system.

By following these tips and using the recommended pressure, you can ensure a thorough and successful blowing out of your RV’s water lines. This winterization process is crucial to protect your plumbing system from potential damage caused by freezing water. Remember to consult your RV’s owner’s manual for any specific instructions or recommendations regarding winterization.
