Reverse Osmosis Water Storage Tank Air Pressure

Use an air pressure gauge to check the current air pressure.

Reverse osmosis water storage tank air pressure.

Re open the tank ball valve. Disconnect the yellow line from the tank valve. Continue to enjoy your reverse osmosis system as usual. Once the air pressure inside is about 2 3 of the incoming water pressure the water flow to the tank stops.

If your feed pressure is 60 psi the membrane will continue to filter water and fill the storage tank until the compressing air within that tank reaches 40 psi. Like we mentioned above an empty ro tank has pressure of 6 to 8 psi. Locate the pressure valve under the blue cap on the tank. Reconnect the yellow line at point y.

Return the tank to its original position and turn the water supply back on. The reverse osmosis system is equipped with a sensory valve that halts the production of water when the pressure in the tank reaches 2 3 of the line pressure. The air compartment is pressurized and as you open the tap the air pushes on the water and it flows out through the tap. Use air compressor or bicycle pump to re pressurize the 4 gallon tank to 5 psi and 7psi for the 14 gallon tank.

A water compartment and an air compartment. The pressure in your reverse osmosis storage tank may too low or too high. Shut the reverse osmosis faucet off and let the tank fill up for 3 hours. 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.

Generally though when an ro tank is empty with no water inside the air pressure should be around 7 to 10 psi. How reverse osmosis tanks work ro pressure tanks have two compartments inside them. Adjust the pressure to 8 lbs by adding air with the bicycle pump and checking it with a low pressure tire gauge. The system shut off valve sold separately will automatically turn the ro system on and off as needed.
