It s the air pressure that pushes the water out of the tank when you open the faucet.
Ro storage tank air pressure.
This video describes how to servic.
The number one reason for low water flow from a reverse osmosis system is due to the holding tank losing its air pressure.
Use an air pressure gauge to check the current air pressure.
Shut the reverse osmosis faucet off and let the tank fill up for 3 hours.
Ro pressure tanks have two compartments inside them.
A water compartment and an air compartment.
Locate the pressure valve under the blue cap on the tank.
Close the tank s ball valve.
Air pressure and reverse osmosis tanks.
Continue to enjoy your reverse osmosis system as usual.
When you purchase an ro unit or a new tank the tank is usually pre charged with air.
Like we mentioned above an empty ro tank has pressure of 6 to 8 psi.
Disconnect the yellow line from the tank valve.
To be accurate the ideal air pressure in a full ro tank should be around 30 to 40 psi to ensure the system operates efficiently.
Turn off the feed water supply to the ro.
Much like the tire on a car the rubber bladder on the inside of a reverse osmosis storage tank can lose pressure over time.
Once this happens water stops flowing into the system and rejected water stops flowing down the drain line.
Drain the old tank completely thru the spigot.
The system shut off valve sold separately will automatically turn the ro system on and off as needed.
Reverse osmosis storage tanks also keep the ro system efficient by turning the system on and off as the tank fills with water and pressure increases.
Reverse osmosis systems utilize pressurized tanks to store purified water until the demand for the water is initiated.
But tanks are like automobile tires.

The air compartment is pressurized and as you open the tap the air pushes on the water and it flows out through the tap.
All reverse osmosis systems including whole house reverse osmosis systems work on pressure.
How reverse osmosis tanks work.
Anytime the storage tank is full and there is full pressure the automatic shut off valve gets automatically triggered.
A pressurized storage tank for reverse osmosis product water is recommended for its ability to deliver reverse osmosis water to the faucet using air pressure within the tank.
