Reverse osmosis water Tank pressure should be well maintained and periodically checked for a reverse osmosis system to function normally. Water tank ensures instant water for use; it is filled when the faucet is shut off until the pressure inside the water storage tank equals the municipal feed water pressure. Once the faucet is opened, water flows out of the water tank due to the pressure inside.
If you don’t get enough water from the faucet, water storage tank is the first thing to look at. An incorrectly adjusted pressure leads often to an unfilled storage tank if the feed water pressure is too much lesser than the storage tank pressure when it is empty. Or to overfilled water tank if the feed water pressure is too much higher than the empty storage tank pressure.
To keep your system operating correctly, check the tank pressure each time you change the filters (7 PSI when empty of water).
Proper tank pressure (7 PSI) must be maintained for the RO system to work correctly. It is preferable to use a specially calibrated air pressure gauge to monitor your system’s air tank pressure to help insure proper system operation.
