Review on 💧 Impressive Reservoir: ISpring T55M Residential Pre Pressurized Storage Solution by Born Waheed

Bought a complete Ispring reverse osmosis system including pump about a year ago with standard 4 gallon tank (3.2 gallon water capacity). We wanted more water storage so we bought the ispring 5.5 (4 gallon capacity). Tested empty pressure is 8.5 pounds (37 pounds full). Once the tank is full it only dispenses 3 gallons of water after a very long 9 minutes, the initial flow is very fast but the extra 2 gallons gradually slow down and become a trickle. It is very frustrating that the hassle and expense was expended to upgrade to a larger tank and have 3 gallon water storage with this 5.5 gallon 4 gallon capacity tank. Ispring support replied that the recommended pressure would be 3-4 gallons. Apparently it's 3 and not 4, and they misrepresented the stated capacity of this tank on the list.
