Choosing The Right Type Of Bleach
Choosing the right type of bleach is crucial for safely sanitizing your RV water tank. Using the wrong type can damage your tank or be harmful to your health. Here’s a guide to help you understand the different types of bleach available and which one is best for your RV water tank.
Household Vs. Industrial
Household bleach is the most common type found in stores. It usually contains 5-6% sodium hypochlorite. This concentration is safe for cleaning and sanitizing your RV water tank.
Industrial bleach is much stronger, often containing 10-15% sodium hypochlorite. This high concentration can be too harsh for your RV water tank and may cause damage. It is best to avoid using industrial bleach for this purpose.
Safe Bleach Options
When choosing bleach for your RV water tank, look for options labeled as safe for drinking water systems. These are usually household bleaches without any added scents, dyes, or other additives. Here’s a simple table to help you choose:
Type of Bleach | Sodium Hypochlorite Concentration | Safe for RV Water Tanks |
---|---|---|
Household Bleach | 5-6% | Yes |
Industrial Bleach | 10-15% | No |
Remember, always use unscented bleach without any additives. This ensures the safety and cleanliness of your RV water tank.
Calculating The Correct Amount Of Bleach
Calculating the correct amount of bleach for sanitizing your RV water tank is crucial. It ensures your water is safe to drink and free from harmful bacteria. Proper calculation prevents the use of too much bleach, which can be harmful, or too little, which can be ineffective.
Standard Measurements
To sanitize an RV water tank, use 1/4 cup of bleach for every 15 gallons of water. This is a standard measurement. It ensures your water is clean and safe. Always use unscented household bleach with 5-6% sodium hypochlorite. This type is effective for sanitizing water tanks.
Adjusting For Tank Size
Not all RV water tanks are the same size. You might need to adjust the amount of bleach. First, know your tank’s capacity. Divide the total gallons by 15. Multiply the result by 1/4 cup of bleach. This gives you the correct amount to use.
For example, if your tank holds 30 gallons of water, divide 30 by 15. The result is 2. Multiply 2 by 1/4 cup of bleach. You need 1/2 cup of bleach for a 30-gallon tank. Using this method ensures accurate bleach amounts for any tank size.
Step-by-step Sanitization Process
Sanitizing your RV water tank is crucial for safe drinking water. Follow this step-by-step process to ensure your tank is clean and bacteria-free.
Preparation And Safety
First, gather all necessary supplies. You will need bleach, a measuring cup, a funnel, and rubber gloves. Safety is important, so wear gloves to protect your skin from bleach. Ensure the RV is parked on a level surface.
Next, turn off the water pump and disconnect any water sources. This prevents contamination. Drain the existing water from the tank using the drain valve. Make sure the tank is empty before you start the sanitizing process.
Sanitizing Procedure
Calculate the amount of bleach needed. Use 1/4 cup of bleach for every 15 gallons of water. Pour the bleach into the tank using a funnel. Fill the tank with fresh water, ensuring the bleach mixes well.
Let the mixture sit for at least four hours. This allows the bleach to kill bacteria and other pathogens. For a more thorough clean, leave it overnight.
After the bleach solution has worked, drain the tank completely. Refill the tank with fresh water to rinse out any remaining bleach. Drain and refill the tank several times until the bleach smell is gone.
Finally, reconnect the water sources and turn on the water pump. Run water through all faucets to ensure the entire system is clean. Your RV water tank is now sanitized and safe to use.

Rinsing And Flushing The Tank
Rinsing and flushing the RV water tank is essential after sanitizing with bleach. This process ensures all bleach residue is removed. It also helps guarantee the water is safe for use. Follow these steps for a thorough rinse and flush.
Removing Bleach Residue
First, fill the tank with clean water. Make sure the water reaches all parts of the tank. Let it sit for a few minutes. This helps loosen any bleach that remains. Now, drain the tank completely. Repeat this process until you no longer smell bleach.
Next, use a hose to rinse the tank. Direct the water to all corners and surfaces. This helps remove any leftover bleach. Be thorough during this step. Any residue can affect the taste and safety of your water.
Ensuring Clean Water
After rinsing, fill the tank again. Use fresh, clean water. Allow the tank to sit for a while. This helps ensure any remaining bleach is diluted. Drain the tank one last time. Check for any bleach smell.
Finally, run the water through your RV’s taps. This ensures the pipes are also free from bleach. Let the water flow for several minutes. This helps clear out any last traces of bleach. Once the water runs clear and has no bleach smell, your tank is clean.
Maintaining A Clean Water Tank
A clean RV water tank is vital for safe drinking water. Regular cleaning prevents bacteria and mold. Proper maintenance ensures water stays fresh. Bleach is an effective sanitizer. But you must use the right amount.
