Check Air Pressure in the Tank
Note: Check air pressure only when tank is empty of water!
Check air pressure in the tank when you notice a decrease in
available water from the RO system.
Step 1 It is recommended that you drain the tank of water, and then
pump up the RO tank in order to ensure all water is out of the
tank. Air can be added with a bicycle pump using the schrader
valve that is located on the bottom side of the tank.
Step 2 Once all water in the tank is purged out, check air pressure of the
tank. If you added too much air to the tank and it is higher than
5 - 7 psi, allow air out until you have 5 - 7 psi in the tank.
