Step by Step Instructions on Sanitizing Your Fresh Water Tank
The sanitation procedure is quite seamless, but the waiting time takes five to eight hours to complete this task.
Step #1: Prepare all materials and take precautions
Choose a premium household liquid bleach to properly and efficiently sanitize rv water tank with bleach. Just take the amount you need, compare prices from different stores, and opt for a reliable brand.
Make sure to clean the funnel with a water hose before use. Also, wear rubber gloves while sanitizing to protect your hands from bleach.
Step #2: Turn off the water heater
Turn off the water heater before you proceed to the next step of sanitation. Keep in mind that if you fail to turn off the water heater while you drain the water tank, it could damage the tank. Additionally, double-check if the water faucets and shower are turned off.
Step #3: Drain the fresh water tank and refill half
To be sure that the water for sanitizing is fresh and clean:
- Drain the water tank.
- Refill the tank with fresh water by half of the tank capacity.
- Remember to never use contaminated, unsafe, and dirty water in sanitizing the RV water tank.
And always have halfway water in the tank before you pour on the bleach.
Step #4: Mix the bleach and water
Mix the bleach and water in the container with the ratio provided above. Make sure you already have your gloves and the mask on while handling the harmful chemical.
Step #5: Pump bleach solution (with control board)
If your RV’s water tank system has a control board, then activate the sanitize setting. And then connect the garden hose to the tank’s inlet, with the other end in the mixing container. Then suction the bleach solution by turning on the water pump.
Make sure that the hose ends are properly secured to avoid breaking the connection.
Step #6: Pour bleach solution (without control board)
To clean RV fresh water tank without an automatic sanitizing system, you need to use a funnel.
Simply connect the funnel to the garden hose securely, and insert the end of the hose to the tank. Then, you can slowly pour the bleach solution into the RV tank for fresh water.
Step #7: Fill the water tank
Once the bleach solution is complete, fill the water tank. And then turn on every water faucet and shower until the smell of bleach emits from the water lines, or after a good two minutes. Then, close all the water faucets and showers and make sure no one will open them until the sanitation is done.
Step #8: Wait for eight hours
Let the water tank system sit for eight hours once all the RV’s water lines are filled with bleached water. A full five hours is good enough, but it is best to wait for a bit longer to ensure that the bleaching process is a huge success.
And to make the waiting time less stressful, disinfect your RV’s water tank during the night. When you wake up, you can proceed with the next step.
Step #9: Drain the tank
After the RV fresh water tank sanitizer processing time, it’s time to drain the water tank with bleach fully. Once drained, fill the \water tank with clean water. Then start flushing the water lines to get rid of the bleach solution and smell.
Repeat the flushing process until the bleach odor is completely gone.
Step #10: Replace water filter
After the flushing process, it is best to replace both the internal and external water filters.
This is an extra security measure for your water’s cleanliness. And after you install new water filters, refill the water tank with clean water. Then, you can start enjoying fresh water for drinking, showering, and washing dishes.
