Why Sanitize Your RV Fresh Water Tank?

Your RV's fresh water tank is a potential breeding ground for bacteria, algae, and other microorganisms. These can cause unpleasant tastes, odors, and even illness. Regular sanitizing is crucial for maintaining safe and healthy drinking water. Failing to sanitize can lead to gastrointestinal issues for you and your family. This guide will help you understand the process and keep your water clean.

Choosing the Right Sanitizer

Several options exist for sanitizing your RV's fresh water tank. Popular choices include:

Bleach: A cost-effective and widely available option. Use unscented bleach to avoid lingering smells.
RV Water Tank Sanitizers: Commercially available products specifically formulated for RVs. These often contain non-chlorine sanitizers. Check reviews before selecting a product.
Hydrogen Peroxide: A natural option that breaks down into water and oxygen, leaving no residue. It's effective but may require a longer contact time.

Remember to always follow the manufacturer's instructions for the chosen sanitizer.

Preparing Your RV Fresh Water Tank for Sanitizing

Before you begin sanitizing, ensure your tank is relatively clean. This step is important to maximize the effectiveness of your chosen sanitizer.

Fill the tank: Fill your fresh water tank about halfway with clean water.
Flush the system: Turn on all faucets to purge any existing water, removing sediment and debris.
Empty the tank: Completely drain the tank. This removes any remaining loose particles or sediment.

The Sanitizing Process: A Step-by-Step Guide

The actual sanitizing process is fairly straightforward, but precise steps ensure thorough cleaning.

Add Sanitizer: Add the recommended amount of your chosen sanitizer to the fresh water tank. Consult the product label for precise measurements. For bleach, a common ratio is ½ cup of unscented bleach per 15 gallons of water.
Fill the tank: Fill the tank completely with clean water.
Circulate the sanitizer: Let the sanitizer circulate throughout the system. This is best accomplished by running the water pump for several minutes. Ensure water flows through all faucets, including the shower.
Let it soak: Allow the sanitizer to remain in the tank for at least 6-8 hours. This extended contact time is critical to kill microorganisms. Ideally, let it sit overnight.

Rinsing Your RV Fresh Water Tank

After the soaking period, thorough rinsing is critical to remove all traces of the sanitizer. Residual sanitizer can leave an unpleasant taste and potentially be harmful.

Drain the tank: Completely drain the tank to remove the sanitizer solution.
Rinse thoroughly: Refill the tank and drain it again several times to ensure all sanitizer residue is gone.
Flush the lines: Run all faucets and the shower for several minutes to flush out the water lines. Taste the water to ensure no sanitizer remains.

Maintaining a Clean Fresh Water Tank

Regular sanitizing is key to maintaining a clean and healthy water supply in your RV. Ideally, you should sanitize your tank every 3-6 months, or more frequently if you notice any unusual odors or tastes. Additionally, consider:

Using a water filter: A filter can help remove sediment and chlorine from your water supply.
Storing your RV properly: If storing your RV for an extended period, completely drain and dry the tank to prevent bacterial growth.

Frequently Asked Questions (FAQs)
