ROmate 15 storage tank lets you easily store and dispense water purified using your building’s reverse osmosis (RO) system. This tank can hold up to 14.3 gallons of water with a 28 psi pre-charge and usable storage between 30/50 psi, although the usable capacity will vary based on the pre-charge pressure and the RO system’s on/off pressure setting. A lower pre-charge pressure will allow the tank to accept more water, but water pressure diminishes faster as water is drawn. A higher pre-charge pressure lets the tank accept less water, but the water pressure diminishes less rapidly as water is drawn. The tank can operate at up to 125 psi, accept a pre-charge of 5-50 psi, and it has a maximum operating temperature of 120 degrees Fahrenheit. It boasts a seamless, corrosion-resistant composite construction and is made using NSF and/or FDA listed materials. Furthermore, the tank can discharge in any position for maximum versatility. It has a 1″ NPT male water inlet and outlet.
