What is a Bladder Tank?
Bladder tanks maintain a supply of high quality water, ready to use anytime you need it. Purified water enters and exits the tank through the same tube. Feed water pressure forces water into the tank. Opening the faucet relieves the pressure and reverses the flow, allowing water to flow through the post-filter and out of the faucet.
The reverse osmosis (RO) bladder tank is pre-pressurized with 7 to 8 lbs. of air. Air pressure does not normally need to be checked or changed. The tank can operate on its base or on its side.
