iSpring iSpring T32M Pressurized Water Storage Tank with Ball Valve for Reverse Osmosis RO Systems 4 Gallon 14 Tank Valve Included

Product Description iSpring T32M 3. 2 Gallon Pressurized Storage Tank for Reverse Osmosis (RO) Systems The reverse osmosis process is on the slower side, so a pressurized storage tank is typically required to supply water from the system on demand. Your RO system will fill the T32M tank to capacity, and when you open your RO water dispenser the water is sent out by the tank's pressurized air bladder. The concern that pollutants may be allowed in when using an open air tank favors the use of a closed expansion tank such as the T32M. The tank uses stainless steel connections to avoid any leaching concerns, tested by independent third-party to meet NSF/ANSI Standard. From the Manufacturer NSF Certified 4.0 Gallon Water Storage Tank (3.2 gallon draw-down) Description Water goes through a reverse osmosis membrane very slowly and people don't have the patience to wait a long time to get a cup of water. For this reason the residential RO units need a water storage tank to store the purified water. The RO tanks can delivery stable and constant water flow when the faucet is opened. The concern that pollutants might come from air or animals with the use an opened tank favors the use of a closed expansion tank. Lead leaching to drinking water the cause of health risks, brass and copper are banned for use in purified/drinking water. This tank uses stainless steel connections to avoid the lead leaching concerns. This tank is NSF approved under standard 58, and CE approved under the PED (pressure equipment directive).
