Pressurizing your reverse osmosis drinking water storage tank is an important part of maintaining you system. It can improve your water flow and performance of your drinking water system.
If your reverse osmosis drinking water storage tank is not working properly, here are some of the issues you may notice. Low water pressure, less volume of water or it may take longer to fill a pot or water container.
If you notice any of these issues, the first thing you should do is check the weight of the reverse osmosis drinking water storage tank. If the tank is heavy (feels full of water) then pressurizing would be the right solution. If the tank is light (feels empty) then the issues may be the filter or membrane may need to be replaced.

After identifying that pressurizing your reverse osmosis drinking water storage tank is what is needed please follow these steps.
1- Shut off the water supply to your reverse osmosis system.
2- Turn your reverse osmosis drinking water tap/faucet on and let the water flow out of it.
3- Let the water run out of the tap/faucet till the water stops. 
4- Locate the valve stem, (looks similar to one found on a car or bike tire/wheel) remove the plastic cover. (be sure NOT to remove the reverse osmosis tank valve)
5- Check the pressure using a PSI gauge.
NOTE: PSI should be between 6psi-8psi when tank is empty for tank sizing between 2 gallon-4 gallon storage tanks. (for the best performance it is alway recommended to read the owner’s manual)
6- If the PSI is below 6psi, use a hand pump, electrical pump or a compressor to add air. (please keep in mind NOT to over pressurize)
NOTE: If any water is remaining in the storage tank, as you add air water will begin to flow once again from the reverse osmosis drinking tap/faucet. Continue pumping and once the water has stopped check the pressure.
7- Once the recommended pressure is achieved, shut the reverse osmosis tap/faucet off and turn the reverse osmosis water supply back on.

My water filter system is a bit outdated but nevertheless Daniel went above and beyond to find a suitable filter that’s compatible with my system & needs.
He also took the time to explain what maintenance is needed when changing my filters. I was really impressed by his professionalism and his customer service.
I will be recommending services to family and friends.
Really appreciate this post thank you!
I didn’t realize that pressurizing a reverse osmosis water tank could help it perform better. Hiring a pressurized storage tank maintenance service would probably be a pretty important thing to do as well. That way you get the benefits of having a system that is well maintained while also increasing the pressure to further improve things!
Thank you so much for sharing this informative post with us. I didn’t know that pressurizing reverse osmosis water storage tank is an important part of maintaining you system.
I didn’t realize that you should check the pressurized PSI gage. It is good to know that the tank should be around 8psi. As a new homeowner, this is good for me to know.
