Pressurizing Your Reverse Osmosis Tank

Have you ever wondered how to properly pressurize your reverse osmosis (RO) tank? Look no further! In this step-by-step guide, I will walk you through the process of pressurizing your RO tank to ensure optimal performance. By following these simple Steps and gathering the necessary tools, you’ll be able to achieve the perfect pressure in no time.

1. Gather the Necessary Tools and Materials

Before we begin, make sure you have all the required tools and materials at hand. You will need a tire pressure gauge, a bicycle pump or air compressor, and some Teflon tape. These items are readily available at most hardware stores or online marketplaces.

2. Shut off Feed Water Supply

Start by shutting off the feed water supply connected to your RO system. This step ensures that no water enters the tank during the pressurization process.

3. Empty Remaining Water from Storage Tank

Next, empty any remaining water from your storage tank by opening a faucet or drain valve. It’s important to ensure that there is no water left inside before proceeding further.

4. Identify and Locate Schrader Valve on Top of RO Tank

Now it’s time to identify and locate the Schrader valve on top of your RO tank. This valve resembles a tire valve and is used for adding air pressure into the tank.

5. Use Teflon Tape for Better Sealing

To prevent leaks while pressurizing, wrap Teflon tape around the threads of the Schrader valve. This simple step helps create a better seal between components.

6. Attach Tire Pressure Gauge for Initial Pressure Check

Attach a tire pressure gauge firmly onto the Schrader valve to check its current pressure levels when empty. Take note of this reading as it serves as an initial reference point.

7. Inflate Bladder Using Bicycle Pump or Air Compressor

Now it’s time to inflate the bladder inside the tank. Using either a bicycle pump or an air compressor, start pumping air into the tank until you reach the recommended PSI (usually between 5-7 PSI).

8. Recheck Pressure and Adjust if Needed

After inflating the bladder, recheck the pressure using a tire pressure gauge. If necessary, adjust the pressure by adding or releasing air until you achieve your desired PSI level.


In conclusion, pressurizing your reverse osmosis (RO) tank is a simple yet essential step to ensure optimal performance. By following the step-by-step guide provided, I have personally experienced how easy it can be to achieve the perfect pressure in my RO system. Properly pressurizing the tank ensures efficient water filtration and delivery, providing clean and refreshing water for you and your family. Remember to periodically check and maintain the pressure levels according to manufacturer recommendations for long-lasting performance. Stay hydrated with confidence knowing that your RO system is operating at its best.
