Sanitizing Your RV’s Fresh Water Tank: A How-To Guide

Owning an RV provides a unique blend of comfort and adventure, giving you the freedom to explore the open road while enjoying the conveniences of home. However, to ensure that your travels are both safe and enjoyable, it’s crucial to maintain your RV properly. One of the most important aspects of RV maintenance is keeping your fresh water tank sanitized. In this comprehensive guide, we will walk you through the steps to effectively sanitize your RV’s fresh water tank. This will help you avoid issues like foul smells, water contamination, and potential health risks.

Why Sanitizing Your RV’s Fresh Water Tank is Important

Maintaining a clean fresh water tank is vital for several reasons. First and foremost, it ensures that the water you use for drinking, cooking, and cleaning is safe and free of harmful bacteria. According to the Centers for Disease Control and Prevention (CDC), waterborne diseases can cause a variety of health issues, from mild gastrointestinal discomfort to severe illnesses.

In addition, a sanitized water system helps prevent the growth of algae and mold, which can produce unpleasant odors and tastes. Regular sanitization also prolongs the life of your RV’s water system, reducing the need for costly repairs and replacements.

When to Sanitize Your RV’s Fresh Water Tank

It’s recommended to sanitize your RV’s fresh water tank at least twice a year, ideally at the start and end of the camping season. However, you should also perform a sanitization process in the following situations:

• When you purchase a new or used RV
• After any period of extended storage
• If you notice any foul smells or tastes in your water
• After filling your tank with water from an unknown or questionable source

Step-by-Step Guide to Sanitizing Your RV’s Fresh Water Tank

Gather Your Supplies

Before you begin, make sure you have the following supplies on hand:

• Household bleach (unscented)
• Measuring cup
• Freshwater hose
• Funnel
• Gloves

Step 1: Drain the Fresh Water Tank

Start by draining any remaining water from your fresh water tank. To do this, open the drain valve and let the water flow out completely. Make sure to turn off the water pump and open all faucets, including the shower and outdoor shower, to allow the system to drain fully.

Step 2: Prepare the Bleach Solution

Next, you’ll need to prepare a bleach solution to sanitize the tank. The standard ratio is 1/4 cup of bleach for every 15 gallons of water your tank holds. For example, if your tank holds 60 gallons, you’ll need 1 cup of bleach. Mix the bleach with a gallon of water in a container or bucket.

Step 3: Add the Bleach Solution to the Tank

Using the funnel, carefully pour the bleach solution into the fresh water tank. Be sure to wear gloves to protect your hands from the bleach. Once the solution is added, fill the tank with fresh water until it is full. This will help to distribute the bleach throughout the entire system.

Step 4: Circulate the Solution

Turn on the water pump and open all faucets, including the shower and outdoor shower, until you smell bleach at each outlet. This indicates that the bleach solution has circulated through the entire water system. Close the faucets and let the solution sit in the tank and water lines for at least 12 hours. This dwell time is crucial for effective sanitization.

Step 5: Drain and Rinse the System

After the bleach solution has had sufficient time to work, drain the fresh water tank and open all faucets to flush the solution out of the system. Refill the tank with fresh water and run it through the system until there is no longer any bleach odor. You may need to repeat this step a few times to ensure all traces of bleach are removed.

Additional Tips for Maintaining Your RV’s Water System

Regularly Inspect Your Water System

In addition to regular sanitization, it’s important to inspect your water system for any signs of damage or wear. Check hoses, connections, and seals for leaks or cracks, and replace any damaged components promptly.

Use a Water Filter

Consider installing a water filter on your RV to help remove impurities and improve the taste of your water. There are various types of filters available, including inline filters, canister filters, and portable filters. Choose one that best fits your needs and budget.

Practice Safe Water Storage

When storing your RV for an extended period, drain the fresh water tank and water lines to prevent the growth of bacteria and algae. If possible, store your RV in a cool, dry place to minimize the risk of mold and mildew.
