The Reverse Osmosis Pressure Tank will allow you to store about 3 gallons of filtered water after your Reverse Osmosis system. Most people do not want to wait for their RO system to make on demand water when filling up a glass for drinking. A Pressure tank will store the filtered water under pressure and allow it to come out at a much greater speed saving you time.

Reverse Osmosis Pressurized Tank 4 Gallon tank

Holds approxamately 3.2 gallons of water.


Reverse Osmosis Tank Shut Off Valve is not included and required for final assembly.

Product Questions

Do I need to add air pressure to this tank?
Question by: Rob on Oct 12, 2022, 9:50 PM
Thanks for reaching out! The tank comes pressurized but does have a bike pump port where you can repressurize it as time goes on.

I previously purchased 6 stage system and want to tap off form it to use also for drinking water, but don’t need the faucet kit as I have most of the parts. Does the tank come with Mur-lok Push Connect fitting? Is there a bracket available to mount this tank on the wall? Do you have instructions for connecting? I assume for 6 stage system, connection should be made just before DI resin, followed by check valve, then ball valve, then this tank. Thanks!

This does not come with the push connect. I have linked it below. As for installation, you are correct in the order.

I have this tank installed in the basement and have a drinking water faucet on the first floor. I have been using for the last few years and I suddenly noticed that there is no more pressure at the faucet. It starts pretty good but it it slows down instantly. Can the tanks go bad/pressure drop after a while? Or is this a different issue?
Question by: Arvind Kandaswamy on Jan 12, 2017, 11:33 AM
Great question! It sounds like your tank has lost pressure. It is common for a pressurized tank can lose pressure over the course of usage. You can find methods of re-pressurizing from a simple internet search! :-)

What us the pressure in PSI of the water coming out of the storage tank? Can the line from the tank be connected directly to the r/o float valve or would the pressure be too high for it to shut off?
Question by: Dawn on Mar 21, 2016, 5:30 PM
Great question!
The pressure in the tank is not all that much, just enough to force the water through. Typically storage tanks are around 5-6 PSI. Using a float valve coming out of the pressure tank can work just as well as a faucet for example and would be a perfect option. Feel free to let us know if you have any further questions!

How do you remove tubing from connectors on the BRS RO/ DI filters?

Hey Chris,
Its not hard at all once you get it down. I included a link to the instructions as the images describe it better then I could by typing it out :-)
