How Do You Winterize A Park Model Trailer

How to Winterize Your Park Model Trailer: A Complete Guide

Winterizing your park model trailer is crucial to protecting it from the harsh elements and preventing costly damage. Neglecting this process can lead to burst pipes, mold growth, and other issues that can significantly reduce the lifespan of your RV. This comprehensive guide will walk you through the essential steps to properly winterize your park model, ensuring it's ready for the cold months ahead.

Preparing for the Winterization Process

Before you begin, gather the necessary supplies. You'll need:

• RV antifreeze: This is not the same as automotive antifreeze. It's non-toxic and safe for your plumbing system.
• Air compressor: Helpful for blowing out water lines.
• Water pressure regulator: To prevent excessive pressure.
• Blow dryer: For drying out hard to reach areas.
• Drain plugs: Ensure you know the location of all drain plugs for your water heater, water tank and low point drains.
• Cleaning supplies: To clean and sanitize the interior and exterior.
• Gloves and safety glasses: Essential for protecting yourself during the process.

Step-by-Step Winterization Guide

Here's a step-by-step guide to winterizing your park model trailer:

1. Empty and Clean Your Tanks

• Fresh Water Tank: Completely drain the fresh water tank. Open the drain valve and let the water flow completely.
• Grey and Black Water Tanks: Empty the grey and black water tanks. Consider using a tank treatment to eliminate odors before you drain them.
• Clean the Tanks: Once empty, use a cleaning solution to thoroughly clean your tanks. This will help prevent the buildup of bacteria and odors.

2. Drain Your Plumbing System

• Low Point Drains: Locate and open the low point drains. These are typically located under your park model. This will drain water from the plumbing system.
• Water Heater Drain: Drain the water heater. Check your owner’s manual for specific instructions, as different water heaters have different drain procedures. Many require opening a valve near the bottom.

3. By-Pass the Water Heater (If Applicable)

Your water heater likely has a bypass system. Using this will prevent antifreeze from entering the water heater. Check your water heater's manual for instructions on how to correctly bypass it.

4. Add RV Antifreeze

• Using an Air Compressor (Optional but Recommended): First use an air compressor to blow out any remaining water in the plumbing system. This is crucial to prevent freezing. Connect the air compressor to your city water inlet.
• Pouring RV Antifreeze: Pour RV antifreeze into each faucet, showerhead, and toilet until antifreeze flows continuously from the drains. Be generous to ensure all pipes are protected.

5. Protect Your Exterior

• Disconnect and Drain External Water Connections: Disconnect any exterior water connections and drain them to prevent freezing.
• Covering the Outside: Securely cover your park model's exterior features like awnings, windows, and air conditioners. This will protect these items from the winter elements.
• Protect your tires: Remove debris and store it on blocks to prevent flat spots in your tires.

6. Winterize Other Systems

• Refrigerator: Refer to your refrigerator's user manual for specific winterization instructions. Some require emptying and leaving the door slightly ajar.
• Toilet: Flush the toilet and add RV antifreeze to the bowl.

7. Interior Preparations

• Ventilation: Ensure proper ventilation to prevent moisture buildup inside your park model.
• Cleaning: Give the interior a thorough cleaning, removing any food items or perishables.

Post-Winterization Checklist

Before you leave your park model for the winter, conduct a final checklist:

• Check all drains are closed.
• Ensure all windows and doors are securely shut.
• Verify the power is turned off and disconnected.
• Confirm all propane tanks are turned off.

By carefully following these steps, you can effectively winterize your park model trailer, ensuring its longevity and safeguarding it against winter's harsh conditions. Remember to always refer to your owner's manual for specific instructions related to your model and to address any concerns with a qualified RV technician.
