Review Your RV Manual

Every RV is unique. Your owner’s manual is an invaluable resource that provides specific instructions for your model’s systems. It will detail the locations of bypass valves, water heater drains, and other crucial components. Don’t skip this step; it’s fundamental to understanding how to how do you dewinterize an RV specific to your rig.

A Pre-Dewinterization Inspection

Before you introduce water or power, take a walk around your RV, both inside and out. This initial check can help you identify potential issues early.

  • Inspect for any signs of rodent or insect infestation.
  • Look for visible cracks or damage to plumbing lines or electrical wires.
  • Check all exterior seams and seals for wear or damage that might have occurred over winter.
  • Ensure all drain plugs are accessible and free of debris.

Reactivating Your RV’s Water System: A Critical Step

The water system is often the most intricate part of dewinterization. This is where most of the RV antifreeze was introduced, and flushing it out properly is key. This section forms the core of any good how do you dewinterize an RV guide.

Bypassing the Water Heater

During winterization, your water heater was likely bypassed to avoid filling it with antifreeze. Now, it’s time to reverse that. Locate your water heater and the bypass valves.

  • Close the bypass valve (if open) and open the hot and cold water inlet/outlet valves.
  • Reinstall the water heater drain plug (if removed) and anode rod (if applicable). Ensure it’s tightened securely but do not overtighten.

Flushing the Antifreeze

This is the main event for getting rid of that pink stuff. Proper flushing is crucial to remove all traces of antifreeze from your lines.

  1. Connect your fresh water hose to the city water inlet. Use a water pressure regulator to protect your plumbing.
  2. Turn on the city water supply.
  3. One by one, open each faucet (hot and cold), shower, and toilet flush valve until clear water flows and all traces of pink antifreeze are gone. Start with the fixture furthest from the water inlet.
  4. Don’t forget the outdoor shower, toilet sprayer, and any low-point drains.
  5. Once clear water runs from all fixtures, close them.
  6. Drain your fresh water tank completely.

Sanitizing Your Fresh Water System

Even if you flushed thoroughly, sanitizing is a vital step to ensure your water is safe for drinking and bathing. This prevents the growth of bacteria and algae.

  1. Calculate the amount of bleach needed: 1/4 cup of unscented household bleach for every 15 gallons of fresh water tank capacity.
  2. Mix the bleach with a gallon of water in a separate container.
  3. Pour the bleach solution into your fresh water tank filler opening.
  4. Fill your fresh water tank completely with potable water.
  5. Turn on your RV’s water pump and open all faucets (hot and cold) until you smell bleach. This means the solution has reached all parts of your plumbing.
  6. Close the faucets and let the solution sit in the system for at least 4 hours, or preferably overnight (12 hours is ideal for a thorough sanitization).
  7. After the dwell time, drain the fresh water tank completely.
  8. Refill the fresh water tank with clean water and flush the entire system again (all faucets, shower, toilet) until no bleach smell remains. You may need to repeat this flush-and-fill process 2-3 times.

Checking for Leaks

After flushing and sanitizing, it’s time for a critical inspection. This is where you identify common problems with how do you dewinterize an RV related to plumbing.

  • With the water system pressurized, visually inspect all connections, under sinks, around the water heater, and near the water pump for any drips or leaks.
  • Listen for any unusual sounds coming from the water pump, which could indicate air in the lines or a leak.
  • Run the water pump for a few minutes and then turn it off. If it cycles on and off by itself, you likely have a leak somewhere in your system.

Propane System Checks

Propane powers many of your essential RV appliances. Safety is paramount here.

  • Visually inspect all propane lines for any cracks or damage.
  • Slowly open the valve on your propane tank(s).
  • Perform a leak test: Mix a solution of dish soap and water, then spray it on all propane connections (tank regulator, lines, appliance connections). Look for bubbles, which indicate a leak. If you see bubbles, tighten the connection or seek professional help.
  • Light your stove burners to ensure propane is flowing.
  • Test your propane detector to ensure it’s functioning.

Testing Electrical Systems

Your electrical system powers almost everything. Take the time to test it thoroughly.

  • Plug into shore power or run your generator.
  • Test all outlets with a simple appliance like a phone charger.
  • Check all interior and exterior lights.
  • Verify that your converter/charger is working by checking battery charging.

Air Conditioning and Heating

Ensure your climate control systems are ready for varying weather.

  • Turn on your RV air conditioner and let it run for a few minutes to ensure cool air is blowing.
  • Turn on your RV furnace and check for proper operation and heat output. Listen for unusual noises.
