57 BEST Tips Winterize RV With Air (EASY) 

Winterize RV With Air

Winterizing your RV is an essential step to protect it from the harsh winter conditions.

One of the effective methods to winterize your RV is by using compressed air.

In this comprehensive guide, we will explore various aspects of winterizing an RV with air and provide expert advice on how to do it effectively.

Understanding the Winterization Process

Before diving into the specifics of using compressed air, let's first understand the winterization process for an RV.

Winterizing an RV involves protecting its plumbing system, water lines, tanks, and other components from freezing temperatures. Failure to properly winterize can lead to costly repairs due to burst pipes or damaged equipment.

Why Use Compressed Air?

Using compressed air to winterize an RV offers several advantages.

It allows you to thoroughly remove water from the plumbing system, ensuring no residual water remains to freeze and cause damage.

Compared to other methods like using antifreeze, compressed air is a cleaner and more environmentally friendly option.

Equipment Needed

To winterize your RV with compressed air, you'll need the following equipment:

• Air compressor: Ensure it has enough capacity to deliver sufficient air pressure.

• Blowout plug: This is a fitting that connects to the RV's water inlet and allows air to be blown through the plumbing system.

• Pressure regulator: Helps control the air pressure to prevent potential damage to the RV's plumbing.

• Air hose: Provides the connection between the air compressor and the blowout plug.

Step-by-Step Winterization Process

Follow these steps to effectively winterize your RV with compressed air:

Step 1: Drain Water Tanks and Lines

• Turn off all water sources in your RV, including the freshwater tank and city water connection.

• Open all faucets and drains to allow the water to drain completely.

• Flush toilets to remove any remaining water from the system.

• Drain the hot water heater and bypass it if necessary.

Step 2: Connect the Air Compressor

• Locate the RV's water inlet connection.

• Attach the blowout plug to the water inlet using a suitable adapter if needed.

• Connect the air hose to the blowout plug.

Step 3: Set Proper Air Pressure

• Turn on the air compressor and adjust the pressure regulator to a safe level (usually between 30-50 psi).

• Make sure the pressure is not too high, as it can damage the RV's plumbing system.

Step 4: Blow Out the Plumbing System

• Begin with the farthest faucet or fixture from the water inlet.

• Open the faucet and let the compressed air blow out the water from the plumbing system.

• Move systematically through each faucet, showerhead, toilet, and any other water outlets, ensuring all water is expelled.

Step 5: Check for Residual Water

• After blowing out the plumbing system, inspect each fixture for any signs of remaining water.

• If you notice water droplets or moisture, continue blowing air until completely dry.

Additional Tips and Precautions

Here are some additional tips and precautions to consider when winterizing your RV:

• Always wear safety goggles and gloves when working with compressed air.

• Never exceed the recommended air pressure to avoid damaging the RV's plumbing system.

• Use caution when blowing out delicate components, such as water filters or water pumps.

• Consider adding antifreeze to drain traps and toilet bowls to provide extra protection.

• Consult your RV's owner's manual for specific instructions and recommendations.
