Winterizing an RV's plumbing to protect from cold weather damage

How to Winterize RV Plumbing

As a homeowner, understanding how to winterize RV plumbing is essential to protect your investment during the cold months.

Proper winterization ensures your plumbing system remains intact, preventing costly repairs due to frozen or burst pipes.

In this guide, we’ll walk you through the entire process, making it simple and straightforward.

When to Winterize Your RV Plumbing

Timing is Key

You should start winterizing your RV plumbing before the first freeze. This proactive approach can save you from headaches later on. Look out for the following signs that indicate it’s time to winterize:

  • Dropping Temperatures: When nighttime temperatures start to dip below freezing.
  • Forecasts of Frost: Keep an eye on local weather reports. If frost is expected, it’s time to act.

Essential Materials Needed

Before diving into the winterization process, gather the necessary supplies. Here’s a quick list of what you’ll need:

  • RV Antifreeze: Non-toxic, pink RV antifreeze is ideal for plumbing systems.
  • Wrenches and Screwdrivers: For removing any fittings or caps.
  • Hoses and Funnels: To help add antifreeze to your system.
  • Towels: Useful for cleaning up spills.
  • Fresh Water Tank Flush Kit: To ensure your tanks are fully cleaned.

By having all these materials ready, you’ll streamline the winterization process.

Step-by-Step Guide to Winterizing RV Plumbing

1. Drain the Fresh Water System

First things first: turn off your water supply and drain the tanks. Here’s how to do it effectively:

  • Turn Off the Water Heater: This step is crucial to avoid damage.
  • Open All Faucets: Start with the highest faucet and work your way down to allow gravity to do its job.
  • Empty the Fresh Water Tank: Make sure no water is left in the system.

2. Add Antifreeze

Once the system is drained, it’s time to add RV antifreeze. Follow these steps:

  • Bypass the Water Heater: Most RVs have a bypass valve. Make sure this is in the bypass position to prevent antifreeze from entering the heater.
  • Use a Pump Converter Kit: Attach the kit to the antifreeze bottle. This makes it easy to pump antifreeze through the system.
  • Run the Faucets: Turn on each faucet, one by one, until you see pink antifreeze flowing. Don’t forget the shower and toilet!

3. Protect the Wastewater System

Your wastewater system needs protection too. Here’s how to winterize it:

  • Drain the Gray and Black Tanks: Open the valves to drain these tanks completely.
  • Add Antifreeze: Pour some antifreeze down the toilet and sink drains. This step helps prevent freezing and cracking.

4. Final Checks and Storage

After completing the above steps, it’s important to conduct final checks:

  • Inspect Hoses and Connections: Look for any signs of wear or leaks.
  • Close All Valves: Ensure everything is securely closed to prevent contaminants from entering.

Once you’ve verified everything, it’s time to store your RV. Make sure you park your RV in a sheltered area if possible, away from direct elements.

Common Mistakes to Avoid

When winterizing your RV plumbing, it’s easy to make mistakes. Here are some common pitfalls to watch out for:

  • Neglecting the Water Heater: Forgetting to bypass the water heater can lead to expensive repairs.
  • Using Automotive Antifreeze: Always choose non-toxic RV antifreeze; it’s safe for your plumbing.
  • Skipping the Wastewater System: Ignoring the wastewater system can lead to frozen pipes and damage.

By being aware of these mistakes, you can take steps to avoid them.
