How to Clean Reverse Osmosis Tank? (Step-By-Step)

Fortunately, cleaning a reverse osmosis tank is not a difficult process, and can be done in a few simple steps.


Disconnect The Tank From Water Supply

The first step in cleaning your reverse osmosis tank is to disconnect it from the main water supply. This will help prevent any debris from entering your water system. To disconnect, locate the tank shutoff valve and turn it off.

If your tank is connected directly to the water line, use an adjustable wrench to loosen the fitting. Once the fitting is disconnected, remove the tank from the system.


Drain The Water From The Tank

The second step in cleaning a reverse osmosis tank is to drain the water from the tank. To do this, you will need to locate the shutoff valve at the bottom of the tank. This valve should be opened so that the water can start to drain.

Once the tank has finished draining, it can be removed from the system. When the tank is away from the system, it should be thoroughly washed with a sponge and warm water. After washing, the tank should be rinsed with clean water and then left to dry before being returned to the system.


Clean The Inside of The Tank

The third step in cleaning a reverse osmosis tank is to clean the inside with a cloth and mild detergent. Make sure to use a cloth that is lint-free, and a detergent that is non-abrasive. Start by wiping down the inner walls of the tank, and then rinse the cloth in warm water.

Use the cloth to scrub off any dirt or residue that may have built up on the tank walls. After you are finished, rinse the tank with warm water and dry with a soft cloth.


Rinse The Tank With Clean Water

Fourth, rinse the tank with clean water. This step removes any remaining residue of the cleaning agents and ensures that the tank is completely free of contaminants.

Be sure to use a clean, soft cloth or sponge to rinse the inside and outside of the tank. You can also use a low-pressure water sprayer or hose to flush out any residual cleaning agents. Once the tank is rinsed, let it air dry before refilling it with water.


Reconnect And Refill The Tank With Water

Once you’ve removed all the parts, it’s time to reconnect and refill the tank with water. The tank needs to be filled with filtered water, not tap water. Once it’s full, reconnect the tank to the rest of the system.

Make sure all the connections are secure and the valves are in the correct position. You may need to use a wrench to tighten the fittings. After everything has been connected, turn the system back on and check for any leaks. If all is well, you’re ready to start using your reverse osmosis system.


In conclusion, cleaning your reverse osmosis tank is an important part of maintaining your system and keeping it running smoothly. It is recommended that you clean your tank every 6 months to ensure that minerals don’t build up and reduce the efficiency of your system.
