How To Clean Reverse Osmosis System? (Step by Step)


You must sanitize, wash, and replace reverse osmosis water filters at least once a year. A clear sanitization procedure should be used to clean and wash the reverse osmosis system. Your reverse osmosis system will not work properly if you do not clear out the contaminated filters from your reverse osmosis system.

You need an excellent sanitizing agent to clean your reverse osmosis system. Using an EPA and NSF-approved product is a good idea, or you can just use your household bleach.

Before trying to clean your reverse osmosis system, remember that you have to keep the new filters in their original packaging. You do not want to contaminate your new filters before placing them in your reverse osmosis system.

Make sure that you clean your reverse osmosis system in a clean place. I put down a nice clean cloth before trying to wash my reverse osmosis system.

I like to wear sanitary gloves while cleaning my reverse osmosis system, and you should do the same. You do not want sanitizing agents or similar chemicals to touch your skin.

I always keep soap and water with me while washing my reverse osmosis system. It is a good idea to wash your hands with soap and water before using your reverse osmosis system.

Check whether your reverse osmosis system is connected to a refrigerator or an ice-maker before starting to wash it. I always first disconnect the supply connecting my reverse osmosis system to the refrigerator or the ice-maker.

The second step is easy. You have to disconnect the cold water supply to the reverse osmosis system. Next, I want to clean all the water from my reverse osmosis system.

So, I just open the water faucet and let the water move out of my reverse osmosis system. I make sure that I have completely drained all the water from the water storage tank of my reverse osmosis system.

Now I can close the water faucet. I like to clean the pre-filter closet first. You will notice the pre-water filter closest to the water inlet pipe.

How to clean reverse osmosis tank?

If you have already sanitized your reverse osmosis system, you do not need to clean your reverse osmosis tank again. However, if you feel that your reverse osmosis tank is not clean, then you should follow these simple steps to clean your reverse osmosis tank:

  • You need to drain the tank and your reverse osmosis system. To do this, you need to open your faucet valve and let the water flow. This may take some time, but it completely drains your reverse osmosis system tank.
  • Now, you need to disconnect your reverse osmosis tank from your reverse osmosis system. To do this, disconnect the tank membrane from your reverse osmosis system.
  • You do not want any water left in the tube. So, let’s drain it.
  • Typically, I use unscented household bleach to clean my reverse osmosis tank. You can also use any NSF-approved sanitizing agent. It depends on you. I have seen people using Hydrogen Peroxide or Chlorine to clean the reverse osmosis system. You can also use these sanitizing agents to clean your reverse osmosis tank.
  • Do not let the sanitizer leak out of your reverse osmosis tank. It is time for you to reconnect the tubing. Make sure that the sanitizer remains inside the reverse osmosis tank.
  • You do not need to open the reverse osmosis dispenser at this point. Opening the tank valve is a good idea.
  • It is time for you to open the water supply of your reverse osmosis system.

  • Let the water enter your reverse osmosis tank. The bleach will do its job. Let the bleach kill all the harmful bacteria and viruses inside your reverse osmosis tank for at least 30 minutes.
  • It is time for you to drain your reverse osmosis tank. Fill it again with water and let it drain two to three times. I refill and drain my reverse osmosis tank at least three times. In this way, I get rid of the unpleasant smell.

How to clean air gap on reverse osmosis?

You have to know how an air gap works on your reverse osmosis system. An air gap prevents the drain water from mixing into your clean drinking water. Plumbers say that an air gap works on the principle of backflow prevention.

So, how do you clean air gap on reverse osmosis?

Experts say you are less likely to face an air gap issue if you properly install your drain saddle. You need to keep your drain saddle away from the disposal. Proper installation always works.

Proper adjustment of the excess tubing can also solve the air gap issue. Do not let the drain saddle move away from the drain holes. Clean the tubing by taking everything apart.

Another simple method used by some people to clean the air gap without taking everything apart is to use a wet paper towel and an air spray. They close the borders of the air gap hole by using a wet paper towel and then use an air spray to clean the air gap hole. It is not a fool-proof method, but it still works for many people.
