Water Tank

How does it work?

iSpring pre-pressurized tanks are perfect for use in under-sink water storage with your reverse osmosis system. The RO 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 tank to capacity, and when you open your RO water dispenser, the water is sent out by the tank's pressurized air bladder.

  • All tanks have a maximum working pressure of 100 psi.
  • iSpring Pre-pressurized tanks are tested by independent third-party against NSF/ANSI standard (61 for Drinking Water System Components) for material safety and structural integrity requirements, 2018.
