iSpring T20M 20-Gallon Pre-Pressurized Reverse Osmosis Tank

A reverse osmosis system is only as efficient as its storage tank, and the iSpring T20M Pre-Pressurized RO Tank is engineered to deliver consistent pressure, reliable output, and long-term durability for households that demand clean water on demand.

Built with high-quality, NSF and ANSI-tested materials, the T20M is designed to safely store purified RO water without compromising taste, purity, or system performance. With a total tank size of 20 gallons and an effective 14 gallons of usable water storage, it provides ample capacity for daily drinking, cooking, and household use—ideal for families or high-usage environments.

One of the standout advantages of the T20M is its pre-pressurized design, which ensures steady water flow and faster delivery to your RO faucet. This eliminates the slow trickle commonly associated with undersized or worn-out tanks, improving overall system efficiency and user experience.

Installation flexibility is another strong point. The tank is designed to function efficiently in both vertical and horizontal orientations, allowing it to fit easily under kitchen sinks, in utility rooms, or in tight cabinet spaces. This adaptability makes it suitable for a wide range of residential RO setups without requiring special modifications.

iSpring includes everything needed for installation right out of the box—such as a shut-off valve, tank connector, and tank stand—reducing additional purchases and simplifying setup. Whether you’re replacing an aging tank or installing a new RO system, the process is straightforward and user-friendly.

From a reliability standpoint, the T20M reflects iSpring’s reputation for long-term performance.
