Maintaining a clean and safe water supply is crucial for enjoyable camping. Disinfecting your camper's water tank regularly prevents the growth of harmful bacteria and ensures you're drinking clean water. This comprehensive guide will walk you through the process, step by step.

Why Disinfect Your Camper Water Tank?

Stagnant water in your RV's water tank is a breeding ground for bacteria like E. coli and other potentially harmful microorganisms. These can cause serious illness. Regular disinfection, even if you don't notice any issues, is essential for preventing problems. Think of it as preventative maintenance for your health!

How to Disinfect Your Camper Water Tank: A Step-by-Step Process

This method uses bleach, a common and effective disinfectant. Always follow the instructions on your bleach container.

Step 1: Empty and Rinse the Tank

Completely drain your fresh water tank. Open all faucets and the low-point drains to ensure complete emptying.
Rinse the tank thoroughly. You can do this by filling it with clean water and draining it several times. This removes loose sediment and debris.

Step 2: Prepare the Disinfecting Solution

Use unscented household bleach. Other disinfectants might not be as effective or safe for consumption.
The standard ratio is ½ cup of unscented bleach per 15 gallons of water tank capacity. Always check your tank's capacity for accurate measurement. If unsure, consult your RV's manual.

Step 3: Fill and Circulate the Solution

Fill the tank with clean water.
Add the measured amount of bleach to the tank.
Turn on all faucets and let the water run for several minutes to circulate the bleach solution throughout the system. This ensures thorough disinfection.

Step 4: Let it Soak

Allow the bleach solution to sit in the tank for at least 12 hours. 24 hours is even better, allowing for more complete disinfection.
Avoid using the water system during this time.

Step 5: Flush the Tank

After the soaking period, completely drain the tank again.
Rinse the tank thoroughly by refilling it with clean water and draining it several times. Continue until the bleach smell is completely gone. This is crucial to remove any residual bleach taste from your drinking water.

Step 6: Verify Cleanliness

Test your water for chlorine after flushing. You can use a chlorine test kit easily found at most camping supply stores. This ensures that the bleach has been thoroughly flushed out.

Alternative Disinfecting Methods

While bleach is common, alternative methods exist:

Silver-based disinfectants: These are effective and leave no residual taste. However, they are generally more expensive than bleach.
UV sterilization systems: These systems use ultraviolet light to kill bacteria and other microorganisms. They are a more permanent solution but require installation.

How Often Should You Disinfect?

The frequency of disinfection depends on usage. Aim for at least twice a year, or more frequently if you notice any unusual smells or cloudy water. Disinfecting before and after extended storage is also highly recommended.

Maintaining Water Tank Cleanliness

Beyond disinfection, consider these steps:

Regularly flush the tank: Even without full disinfection, flushing the tank every few uses will help remove sediment and prevent bacteria buildup.
Use a water filter: A good water filter will remove sediment, chlorine, and other impurities, improving the taste and quality of your water.
Avoid leaving stagnant water: If you know you won't use your camper for a while, drain the tank completely.

Following these steps will ensure you always have clean, safe water during your camping adventures. Remember to prioritize your health and enjoy the journey!
