Tips on How to Sanitize RV Water Tank

Step #1 Sanitizing the Cleaning Tools

The first thing that you need to do is to start disinfecting the cleaning tools that you have. This includes the hose and funnel using the pure bleach. You can leave it for 15 minutes and then discard the pure bleach in the funnel. You should also pour the regular bleach using the funnel and the clear hose to the fresh water fill.

Choose Filters for Indoor and Outdoor Aquariums

Step #2 Refilling the Water Tank

The next thing that you need to do is to start refilling the RV water tank with fresh water until it starts overflowing from the hose or until it gets full. Once full, you can turn the water supply off. You can then activate the water pump as this will help draw water from the water tank.

Step #3 Letting the Water Flow

Start opening every faucet that you have in your RV and wait until you start smelling the regular bleach. Once you start smelling it, you may turn all of the faucets off. When doing this, it would be best to shut down the power of your water heater. This will prevent burns and injuries once you start working on the faucets with your hands.

Step #4 Waiting Time

After doing step three, you can now turn the fresh water supply on. You may even add a few number of gallons to the tank if needed. Once done, then you can wait for it to start working. Typically, it would be best to wait for it least 4 hours for the water system to be fully sanitized. Some people even wait for 6 hours.

Step #5 Flushing the Water Out

After the said hours, you can turn the fresh water supply off and turn the water pump on. Once done, you can start flushing the water out of the lines by ensuring that all faucets are open. You can leave them open until there is no longer smell of regular bleach. Now, if the smell does not diminish, you can repeat steps 3 and 4.

You can also eliminate the smell by using a vinegar solution. You can create one by mixing a quart of vinegar to five gallons of water. Once done, you can repeat steps 3 and 4. For people who don’t know, vinegar can help eliminate odor and disinfect things, which makes it a perfect cleaning solution.

Step #6 Removing the External Filter

Turn the RV’s water supply off and remove the old external filter. You will need to replace it with a new filter. When doing this, you need to make sure that the pump is turned off and that the internal water filter is replaced with a new cartridge. It would also be best to dab a small amount of petroleum jelly on the filter body’s O-ring. The reason behind this is because it will make the changing of the cartridge easier the next time.

Step #7 Dealing with the Water Heater

Of course, you also need to take care of your water heater. To do this, you can turn the heater off together with the water supply to your RV. Expel any remaining pressure by opening the valve which is located on top of your water heater. Now, you can open the drain valve on your water heater. Leave it like that until all of the water insides is gone.

There will be an anode which you can inspect and replace if needed. If replacement is necessary, then do it before closing the relief and as well as the drain valve. Once done, you can turn the water supply to your RV on and refill the water heater. Before turning the power on, it would be best that all of the air is completely expelled from the heater.

These are the tips on how to sanitize RV water tank without the need of professional help. Always put in mind that cleaning the water tank is important because if you leave it unsanitized,  it can cause some serious health issues not only to you but your entire family. As you all know drinking water that is contaminated can cause certain illnesses.

Drinking water that comes from a clean water tank will not only keep you and your family safe, but it will also ensure that you are not drinking something that might cause nothing but danger.
