How to Drain Your RV Fresh Water Tank: A Step-by-Step Guide

So, you're ready to winterize your RV or perhaps just need to clean out your fresh water tank? Draining your RV's fresh water tank might seem daunting, but it's a straightforward process once you know the steps. This guide will walk you through how to completely drain your RV fresh water tank safely and efficiently, ensuring your RV is ready for its next adventure.

Understanding Your RV's Fresh Water System

Before you begin, it's important to understand the components of your RV's fresh water system. This typically includes:

• The Fresh Water Tank: This is the large tank that holds your potable water.
• Water Pump: This pump pushes water from the tank to your faucets and other fixtures.
• Low-Point Drains: These are located at the lowest points of your water lines, allowing you to completely drain the system. They're usually easily accessible under your RV.
• City Water Hookup: This allows you to connect to an external water source.

Knowing where these components are located in your specific RV is crucial for a smooth draining process. Consult your RV's owner's manual if you're unsure.

Step-by-Step Guide to Draining Your RV Fresh Water Tank

Here's a comprehensive guide to help you efficiently drain your RV fresh water tank:

1. Turn Off the Water Pump

This is the most important first step. Ensure the water pump is turned OFF. This prevents water from being continually pumped into the tank as you drain it. You'll find the pump switch typically inside your RV, near the water control panel.

2. Locate and Open the Low-Point Drains

Locate the low-point drains. These are usually valves located under your RV. Open these drains completely to allow water to flow freely. You may need a wrench to loosen some valves.

3. Open the Water Tank Drain Valve

Your fresh water tank also has a drain valve. This is usually located near the bottom of the tank itself, often outside the RV's underbelly storage area. Open this valve fully to drain the water from the tank. This might require a wrench as well.

4. Let Gravity Do Its Work

Now, it's time to let gravity do the work. It might take some time for the water to completely drain, depending on the size of your tank and the slope of your RV. Be patient and allow sufficient time for the tank to empty.

5. Flush the Lines

Once the tank is mostly empty, you might want to further flush the lines to remove any remaining water and prevent buildup. You can do this by connecting a garden hose to the city water inlet and running water through the system for a few minutes. Then, open each faucet one by one to help flush out any lingering water.

6. Close the Drains and Valves

Once all the water has drained, close all the low-point drains and the water tank drain valve tightly. This will prevent leaks and protect your system from the elements.

7. Inspect for Leaks

After draining, inspect the area around the drains and valves for any signs of leaks. Address any leaks immediately to prevent future problems.

Tips for Maintaining Your RV Fresh Water Tank

• Regular Cleaning: Regularly clean your fresh water tank to prevent the buildup of bacteria and sediment. This can typically be done by adding a tank cleaning solution and thoroughly flushing the system.
• Winterization: If you live in a climate with freezing temperatures, it’s crucial to properly winterize your RV’s fresh water system to prevent damage from freezing.
• Regular Inspection: Periodically inspect your water lines and valves for any signs of damage or leaks.

By following these steps, you can confidently and effectively drain your RV fresh water tank, ensuring a clean and properly maintained system. Happy travels!
