Sanitizing a recreational vehicle’s fresh water tank with a chlorine bleach solution is a common practice to eliminate bacteria and other harmful microorganisms, ensuring potable water. The precise amount of bleach required depends on the tank’s capacity. A common guideline is to use a quarter cup of unscented household bleach (approximately 60 ml, containing 5.25%6.15% sodium hypochlorite) for every 15 gallons (approximately 57 liters) of water tank capacity. This creates a concentration suitable for disinfection without leaving an unpleasant taste or odor once the tank is thoroughly rinsed.
Maintaining a clean water system in an RV is crucial for the health and well-being of those using it. Regular sanitization prevents the buildup of biofilm, which can harbor harmful bacteria and affect water taste and odor. Historically, various methods have been employed for water purification, but using a dilute bleach solution has become a standard practice due to its efficacy, affordability, and accessibility. Properly sanitizing the tank ensures safe drinking water, extends the life of the water system components, and contributes to a more enjoyable RV experience.
