Overview

The iSpring T20M is a purpose-built 20-gallon pre-pressurized storage tank designed for residential reverse osmosis (RO) systems. It stores purified water and provides a steady flow when you open the faucet, helping you enjoy a reliable supply without long waits. With a closed expansion design, it minimizes exposure to air and potential contaminants while supporting both pump and thermal tank configurations.

Why choose the T20M for your RO setup

  • The tank holds 20 gallons total (14 gallons for water and 6 gallons for air), helping maintain a consistent output at the tap.
  • Stainless steel connections are used to help minimize lead leaching concerns in drinking water systems.
  • Independently tested to meet NSF/ANSI standards and CE approved under the PED, with IAMPO listing for added peace of mind.
  • Versatility: Suitable for pump tank and thermal tank applications, and compatible with many standard home RO installations.
  • Installation flexibility: The tank supports both vertical and horizontal positioning for easier setup in tight spaces.

What’s included and how it fits your system

  • All-in-one package: Shut-off valve, tank connector, and tank stand are included, helping you get running without extra purchases.
  • Water quality considerations: A high-grade butyl diaphragm and post-cure processing contribute to a tasteless and odorless water chamber.
  • Long-term service: The design emphasizes durability and reliability, with third-party testing and ongoing customer support.
