Sanitizing your RV’s freshwater system is a critical step in maintaining the health and safety of your drinking water while on the road. Whether you’re setting off for a long-term trip or simply using your RV as a weekend getaway, regular sanitization can prevent a host of potential problems. Here’s why you need to sanitize your RV freshwater system:


1. Prevent Harmful Bacterial Growth

Over time, stagnant water in your RV’s tanks and lines can become a breeding ground for bacteria, including pathogens like E. coli. Even trace amounts of bacteria can cause gastrointestinal illnesses, particularly if the water isn’t used frequently. Regular sanitization with a proper disinfectant—typically a diluted bleach solution—helps eliminate these harmful microbes, ensuring your water remains safe to drink.

2. Eliminate Biofilm and Algae

Biofilm, a slimy layer that forms on the inner surfaces of your freshwater system, can harbor bacteria and fungi. In addition, algae and other organic materials might develop, especially during warmer months. These contaminants not only compromise water quality but can also affect the taste and odor of your water. A thorough cleaning process breaks down and removes these unwanted layers.

3. Protect Against Unreliable Water Sources

If you frequently refill your tanks from various sources—like campgrounds or public water stations—the quality of water may vary. Even if the water appears clear, it might contain contaminants or sediment that settle in your system over time. Sanitizing your freshwater system helps mitigate any risks associated with these variable water sources, ensuring you always have clean, safe water on board.

4. Maintain Equipment Longevity

Regular sanitization is not just about the water—it also protects your RV’s plumbing and water treatment equipment. Deposits from bacteria, algae, or mineral buildup can lead to clogs and corrosion in your water lines, faucets, and pumps. Keeping your system sanitized extends the life of your equipment, potentially saving you from costly repairs or replacements down the road.

5. Peace of Mind on the Road

When you’re traveling, especially in remote areas, the last thing you want to worry about is the safety of your drinking water. By routinely sanitizing your freshwater system, you ensure that every sip of water is as safe as it would be from your home tap. This proactive maintenance measure provides peace of mind and lets you focus on enjoying your adventures.


How we Sanitize Your RV Freshwater System

  • Prepare a Solution: Typically 5.25% sodium hypochlorite. The general recommendation is about 1/4 cup per 15 gallons of water in your system.
  • Fill Your System: Fill your freshwater tank with water and add the solution.
  • Circulate and Soak: Run the water through all faucets and let the system sit for 24 hours to allow the solution to disinfect the entire system.
  • Flush Thoroughly: After the waiting period, drain the tank and flush the system with clean water until the odor is gone.

Regularly sanitizing your RV’s freshwater system—ideally every few months or after every long period of non-use—ensures that you maintain a clean and safe water supply, making your journey as worry-free as possible.

By taking these steps, you’re not only protecting your health but also investing in the longevity of your RV’s water system and overall travel experience. Safe travels and clear skies!
