【Innovative Solution for Tankless RO Systems】The tiny water storage tank is specifically designed to effectively solve the inherent disadvantages of tankless RO systems: a) occasional system pulsation caused by unstable water pressure, especially when connected to a refrigerator or a distant water point. b) initial time lag in the water output of the tankless reverse osmosis system. 

【Super Easy to Install】The mini water tank is incredibly easy to install thanks to the 1/4-inch quick connector. Simply cut the RO system's water line and insert the tank between the openings. The package includes a blade, a 3-way quick connector, a ball valve, a tank, and a tank base. Everything you need for installation is included. 

【Durable & Guaranteed】The stylish small water storage tank in black has been rigorously tested for tank integrity, pressure resistance, durability, and material safety. It comes with a 1-year warranty.

【Premium Quality and Safe】The mini tank is made of 100% food-grade materials, is fully recyclable, and 100% safe to preserve an effective amount of water. Although it's pocket-sized, it's sturdy and strong enough to withstand high pressure. 

【Water Storage Tank Dimensions】The mini water tank (4.5 x 4.5 x 8 inches) conforms to the design concept of a reverse osmosis water heater, compact and slim enough to fit under almost all kitchen sinks. Perfectly fits the Frizzlife PD600, PD600TAM3, PD500, PD400, PX500, and PX500-A tankless water heaters.
