How Long Should You Keep Fresh Water in Your RV Tank?

Maintaining the quality of fresh water in an RV tank is a prime concern for travelers who enjoy the freedom of the road while carrying the comforts of home with them.

Ensuring a supply of clean and safe drinking water involves knowing how long to keep water in an RV fresh water tank before it becomes unsafe for consumption.

While some travelers might think it's as simple as filling up the tank and hitting the road, the reality is that water stored in an RV's tank can become contaminated over time, making it unsuitable for drinking or even for use in cooking and cleaning.

It's important for RV owners to understand the risks associated with stale water, including the growth of bacteria and other microorganisms.

To safeguard health, ensuring clean water requires regular monitoring and maintenance of the RV's fresh water system. Questions frequently arise about how long fresh water can be stored in an RV tank and which practices can extend its safe usage.

Sanitization, a fundamental process for maintaining water quality, must be conducted regularly; but equally important is the knowledge of when it's time to empty and refill your water tank. Balancing the need for a convenient water supply with the importance of water safety is key for any successful road trip.

How To Keep Your Fresh Water Tank Clean and Keep Water Fresh

Maintaining a clean fresh water tank is crucial for both the longevity of your RV's water system and your health. Let's dive into how you can keep your RV fresh water tank in tip-top shape and ensure your water stays fresh.

Sanitize Your Fresh Water Tank

Before you hit the road, make sure to sanitize your fresh water tank. A bleach solution is commonly used—mix a quarter cup of household bleach with a gallon of water for every 15 gallons your tank holds.

Fill the tank, run the solution through all the taps, and let it sit for a few hours. Afterward, thoroughly rinse the tank to remove all traces of bleach.

  • Frequency: At least once every six months
  • Method: Bleach or vinegar solution

Use an Inline Water Filter

Investing in a high-quality inline water filter ensures you're not inviting contaminants into your tank.

From a simple carbon filter to a more sophisticated system with UV light, the market has several options to suit your needs.

  • Types: Carbon, UV light, sediment
  • Benefits: Reduces contaminants and improves taste

Keep Your Potable Water Hose Clean, Sanitized, and Separate from Everything Else

Your potable water hose is your lifeline to clean water. Rinse it with a bleach solution, and ensure it's completely dry before storing it in a sealed and clean plastic bag away from your sewer hoses to avoid cross-contamination.

  • Maintenance: Regular cleaning and separate storage
  • Importance: Prevents mold, algae, and bacterial growth

Know the Quality of the Water You Fill Up With

Not all water is created equal. When you fill-up your tank, it's essential to know the source. City water is usually chlorinated and less likely to introduce contaminants than water from a remote or natural source.

  • Consideration: Source and treatment of water
  • Action: Use a filtration system for added security

Does Fresh Water Go Bad in an RV Fresh Water Tank?

Fresh water in an RV tank can become stale or develop a foul odor over time. It's crucial to understand that water itself doesn't "go bad," but the quality can degrade due to bacterial growth and other factors when stored for extended periods.

Stagnation and Bacteria

  • Stagnant water is a breeding ground for bacteria.
  • Lack of movement allows for the proliferation of microorganisms.

Taste and Smell Concerns

  • Over time, water can acquire a plastic taste or foul odor, hinting at potential contamination or the need to clean the tank.

Potable vs. Non-Potable

  • Only fill your RV tank with potable water to ensure safety.
  • Non-potable water sources increase the risk of contamination.

Bottled Water as an Alternative

  • Many choose bottled water for drinking to avoid potential tank issues.
  • Using the RV tank mainly for non-consumptive purposes.

Regular Maintenance

  • Sanitize your RV's fresh water tank regularly to maintain water quality.
  • Routine sanitization can prevent the water from becoming unsafe.

How Often Should You Sanitize RV Fresh Water Tank

Keeping your RV's fresh water tank clean is crucial for ensuring the water is safe for consumption and free from harmful bacteria. It is generally recommended to sanitize your tank at least once every six months to maintain optimal cleanliness and safeguard your health.

If you use your RV frequently or the water has been stagnant for a while, more frequent sanitation may be necessary.

When to Sanitize

  • At least every six months as standard maintenance.
