3 Ways to Sanitize an RV Water Tank and Water Lines
As an avid RV enthusiast who loves road-tripping across the country, keeping my RV’s fresh water system clean is a top priority. Nothing spoils an amazing destination like contaminated drinking water or bacteria-laden shower water. That’s why I make it a point to thoroughly sanitize my RV’s fresh water tank and lines on a regular basis.
Over my many years of RVing, I’ve tried every trick and technique to sanitize and disinfect my water system. That’s why I’m here to share my tried-and-true process using three common sanitizing methods – bleach, commercial RV cleaners, and vinegar. Whether you’re dealing with a brand new RV fresh water system or one that’s been sitting all winter, these methods will have you on your way to fresh, potable water in no time.
Way 1. Use Bleach
Bleach is the most effective way to sanitize RV water tanks and water lines, but it is important to use it carefully and follow all safety instructions.
Step 1: Turn off the water heater and pump.
Step 2: Bypass the water heater and filter.
Step 3: Drain the system by opening the low-point drain valves.
Step 4: Close the low-point drain valves.
Step 5: Fill the tank with fresh water until it is about 3/4 full.
Step 6: Add 1/2 cup of bleach for every 10 gallons of water in the tank.
Step 7: Turn on the water pump and flush the system by opening all of the faucets and running water until you smell bleach.
Step 8: Close all of the faucets and let the bleach solution sit in the tank for at least 6 hours.
Step 9: Drain the tank and flush the system again with fresh water until you can no longer smell bleach.
Step 10: Turn on the water heater and pump.
Way 2. Using vinegar
Vinegar is another effective way to sanitize RV water tanks and water lines. It is less harsh than bleach, but it will not kill all types of bacteria.
Step 1: Follow steps 1-3 above.
Step 2: Fill the tank with fresh water until it is about 3/4 full.
Step 3: Add 1 gallon of vinegar for every 10 gallons of water in the tank.
Step 4: Follow steps 7-10 above.
Way 3. Use a commercial RV sanitizer
There are a number of commercial RV sanitizers available that are specifically designed to sanitize RV water tanks and water lines. These products are easy to use and follow the instructions on the product label.
Step 1: Follow steps 1-3 from way 1.
Step 2: Fill the tank with fresh water until it is about 3/4 full.
Step 3: Add the RV sanitizer to the tank according to the product label instructions.
Step 4: Follow steps 7-10 from way 1.
Why Sanitize the RV Water Tank and Lines?
Now you already know the methods, but there’s “but” still remains. Why properly sanitizing your RV water system is so important after all? Here are the reasons –
- Removes bacteria, viruses, mold, algae, and other microorganisms
- Prevents foul tastes and odors
- Improves water flow by removing scale and buildup
- Ensures fresh, clean drinking water for your health
- Helps tanks, pipes, and fixtures last longer
Neglecting to sanitize can lead to symptoms like upset stomach, nausea, and diarrhea from contaminated water. It’s a quick and easy process that pays off every time you turn on the faucet or take a shower in your RV.
