Regular cleaning helps prevent the growth of bacteria and contaminants that can make you sick. In this guide, we will provide step-by-step instructions and best practices for cleaning your RV’s fresh water tank.

Key Takeaways

Why Cleaning Your RV Water Tank is Important

Cleaning your RV water tank is of utmost importance to maintain the safety and quality of the water you consume while on your travels. Neglecting to clean your water tank can expose you to a range of risks and health hazards.

One of the primary reasons why cleaning your RV water tank is crucial is the presence of bacteria. Most water carries bacteria, and when left untreated in an enclosed space like a water tank, these bacteria can rapidly multiply. This creates an environment conducive to the growth of harmful bacteria such as Legionella and E. coli, which can cause severe illnesses.

Beyond bacterial growth, your RV’s fresh water system is susceptible to contamination over time. Dirt, sediment, and particles can accumulate in the water tank, leading to compromised water quality. Consuming contaminated water can result in digestive issues, infections, and other health complications.



To ensure the water in your RV is safe and clean for drinking, showering, and cooking, regular cleaning of your water tank is essential. By following proper cleaning procedures and using suitable cleaning products, you can mitigate the risks of bacterial growth and water contamination in your RV.

How to Clean an RV Fresh Water Tank

Cleaning your RV’s fresh water tank is a straightforward process. Here are the steps to follow:

  1. Close all taps and valves in your RV, including the hot water tank drain and relief valve.
  2. Choose a cleaning product specifically designed for RV water tanks, such as Puriclean or Steradent.
  3. Add the recommended amount of the cleaning product to your fresh water tank.
  4. Fill the tank completely with fresh water using a hose or bucket.
  5. Turn on the tap furthest from the fresh water tank to allow the cleaning solution to flow through the entire system. Let the water run for 10-15 seconds or until you can smell the cleaner.
  6. Leave the cleaning solution in the tank overnight or drive around for a while to allow it to reach all corners of the tank.
  7. The next day, open all taps to allow the cleaning solution to flow into the grey waste tank and clean it as well. Pour some cleaning solution down the drains in the kitchen and bathroom.
  8. Completely empty the freshwater tank and refill it with clean water. Repeat this process until the tap water no longer smells of the cleaning solution.
  9. Consider changing your water filters to ensure the entire system is clean and ready to use.

Tips for Maintaining Your RV Water Tank

To ensure the long-term cleanliness and safety of your RV water tank, it is important to follow regular maintenance practices. By taking these preventive measures, you can minimize the risk of contamination and keep your water supply fresh.

  1. Do not fill your water tank completely: Avoid filling your water tank to maximum capacity to reduce weight and prevent the formation of stagnant water. This helps maintain better water quality and reduces the likelihood of bacterial growth.
  2. Fill up small amounts frequently: Instead of filling up your water tank all at once and using the water over several days, consider filling it up with smaller amounts more frequently. This ensures a fresh supply of water, as it will be consumed and replenished more regularly.
  3. Empty your water tank after each trip: After every RV trip, especially if you won’t be using your RV for an extended period, make sure to empty your water tank completely. This prevents the accumulation of stagnant water and reduces the risk of bacterial contamination.
  4. Run water through your pipes regularly: Routinely running water through your RV’s pipes helps keep them clean and prevents the growth of bacteria. This simple practice flushes out any stagnant water and ensures a fresh water supply.
  5. Clean your RV water tank at least twice a year: Regular cleaning of your RV water tank is vital to maintaining its cleanliness. Aim to clean your water tank at least twice a year, preferably after bringing your RV out of winter storage or during hot summer months. This helps remove any sediment, bacteria, or contaminants that may have accumulated over time.
  6. Consider using filtered or boiled water for drinking: To ensure additional safety, you may choose to use filtered or boiled water for drinking purposes. This extra precaution helps eliminate potentially harmful bacteria or impurities that may be present in the water.

By following these maintenance tips, you can prevent contamination and ensure a clean and safe water supply for your RV adventures.

Is it Safe to Drink Water from Your RV Water Tank?

The safety of drinking water from your RV water tank is a topic of debate. Some people prefer to filter or boil the water before consuming it to ensure additional safety. Others are comfortable drinking the water directly from the tank. It is recommended to use a filtration system or boil the water if you have any concerns about the quality or cleanliness of the water in your RV water tank.

If you are unsure about the safety of the water in your RV water tank, there are a few options you can consider:

  1. Filtering: Using a water filtration system can help remove impurities, bacteria, and contaminants from the water. There are various types of filters available, such as carbon filters, UV filters, and reverse osmosis systems. You can choose a filter that suits your needs and install it in your RV’s water system to ensure clean and safe drinking water.
  2. Boiling: Boiling the water is a simple and effective method to kill bacteria and other waterborne pathogens. By bringing the water to a rolling boil for at least one minute, you can effectively make it safe for consumption. Keep in mind that boiling may not remove certain chemicals or toxins, so it’s essential to address these concerns with additional filtration methods if necessary.

It’s important to note that even if you choose to filter or boil the water from your RV water tank, regular cleaning and maintenance of the tank itself are still crucial. Cleaning your RV fresh water tank and following proper hygiene practices will help ensure the safety and quality of your drinking water.
