Thankfully I had read up on these RO tanks when my 5 year old iSpring one broke (bad bladder) and I knew that there was a way to check and adjust the pressure/PSI of the tank. The replacement tank I received had only 3 PSI of pressure when the suggested PSI should be between 7-9 PSI of pressure. It's easy to check with a tire gage and can be filled with a compressor or bike pump but IMO it should leave the factory at the correct pressure. Low tank bladder pressure will affect how much water you can dispense before your RO faucet runs at a trickle. A properly pressurized tank should dispense 2-2.5 gallons before slowing down to a trickle. Installation was simple once I corrected the pressure in the tank.
