Frizzlife MWT3 Mini Water Tank for Tankless RO Systems – 0.13 Gal, 1/4in Ball Valve

The Frizzlife MWT3 Mini Water Tank is a compact 0.13-gallon pressurized reservoir designed for tankless reverse osmosis systems. When paired with models such as PD400, PD500, PD600, PX500, and PX500-A, it helps smooth out water draw and minimizes the pulsing often felt with variable line pressure. A quick-start flow can reduce the initial delay between opening a tap and receiving purified water, delivering a more consistent experience across kitchen fixtures, refrigerators, and coffee stations.

What makes it useful in daily use

• Stabilizes fluctuating water pressure in tankless RO setups, supporting steadier, more reliable output.
• Shortens the initial lag, so water begins flowing sooner after activation.
• Simple 1/4 inch quick-connect installation that sits neatly between the RO outlet and your supply line.
• Small footprint (4.5 x 4.5 x 8.3 inches) that fits under most kitchen sinks without crowding the space.
• Durable build with 100% food-grade materials, designed to withstand regular use and high-pressure situations.
• Compatible with G2, G3, P600 and other tankless RO configurations, including RO500 and related models.

• Mini water tank, base, and mounting options
