How to Clean and Sanitize RV Freshwater Tank
Cleaning and Sanitizing your RV fresh water tank means you will get crystal clear water that will be safe for consumption and use. This really a task that being an RVer, you should do by yourself instead of hiring a professional and paying them.
If you have read all the requirements and guidelines, and you think you are ready, follow the below steps,
1. Turn Off the Water Heater and Drain Freshwater System
The very first step and that you should always remember when you clean and sanitize the RV fresh water tank is to turn off the water heater before you drain the freshwater tank. Failing to do so means you will severely damage your water heater system. To make sure you get the last bits of water out of your RV freshwater system is to use a water pump.
2. Calculate the Amount of Bleach You Are Going to Use and Then Add it to the RV’s Freshwater Tank
Now, what you’ve to do is to calculate the bleach. You may want to add ¼ cups of bleach for every 16 gallons of water in the RV’s freshwater tank (Or one ounce for every 8 gallons). Keep the calculations based on the ratios.
For example, if your RV tank can hold 20 gallons of freshwater, you will need 2.5 ounces of bleach for sanitizing the freshwater tank.
Avoid adding bleach directly to your RV fresh water tank as you have to dilute it first. Now, add the bleach amount using the calculations as mentioned above and add it in at least one gallon of water. Now, you have to use the funnel to pour that mixture into your RV’s freshwater tank.
3. Use the Portable Water to Fill the Freshwater Tank
Now, you may want to fill the RV’s freshwater tank by adding consumable portable water. Make sure you fill the RV fresh water tank to its fullest. This will help to sanitize the whole freshwater tank and other systems. Moreover, you may also want to make sure that the bleach water that you are using to sanitize the RV fresh water tank gets all the way through the freshwater system.
In this regard, you are required to switch on all the faucets to make way for the bleach water to reach every corner of the system. Once the water circulates through all the systems, you may now turn off the faucets.
4. Keep the Water Inside the Freshwater tank for at Least 12 Hours
As I have stated in the start that the process will take up to 12 hours, the bleach water will need some time to sanitize the RV fresh water tank thoroughly. It cannot be done by just running the water through the freshwater tank in no time and hoping all is good. You should let the water sit in for at least 12 hours. It will make sure that the freshwater tank is clean and deeply sanitized.
5. Drain the RV Freshwater Tank and Flush the System
After you have let the bleach water sit inside the freshwater system for 12 hours, now it’s time to drain all the water out. Once you have drained the bleach water, you are now required to fill the freshwater tank again and circulate the water throughout the freshwater system. In this regard, you can use the water pump.
Once the water circulation is completed, open all the faucets again and flush the system until there is no bleach smell remaining in the water. However, the process of flushing the system might take some, and you have to do it three to four times, but don’t panic. To get the best possible outcome, I highly recommend keeping flushing the system even after the bleach smell is gone.
Doing it will make sure that there is no bleach chemical water remaining in the system. Once you are done sanitizing your RV freshwater tank, you may also want to change the water filters. After replacing the water filter and switching the water heater system back on, you are now all set to take your rig out for your next adventure.
How to Keep your Freshwater Tank Clean?
Since the freshwater inside your RV’s freshwater tank comes from multiple sources, it is hard to tell how pure and clean it is. Although most of the campgrounds provide clean water from clean resources, some also use municipal sources. If the water that you are getting in your RV’s freshwater tank and storing it for an extended period, it may incubate a colony of bacteria.
So, how to eliminate RV water contamination?
You should take some preventive steps to make sure to eliminate the risk of bacteria you ingest. Below, I have listed some preventive habits that, as an RVer, you should add to your routine.
- Make sure to check the water source that is supplying the water to your RV’s freshwater tank. If you are at a campsite, you can ask the campground manager if they are supplying municipal water or well water. If it is coming from a well, it should be tested regularly.
- The second best preventive habit is installing water filters. You should install a water filter at the kitchen faucet, and another is at the source.
- However, if you are unable to test the water quality or not sure if the water is clean, you should boil the water before consumption. Moreover, you can also keep bottled water with you.
- Another essential step is you should never touch your RV’s freshwater hose without washing your hands. Also, make sure that you keep it off the ground.
- You should also wash your hands each time you use the dump station or hook up the waste tank drain. Furthermore, you should never use the water from the dump station for filling your RV tank if it is not clean and not consumable.
- Last but not least, you should make sure to sanitize your rig before you store it for extended periods of time.
