6) How Full Can My Tank Fill Up?
Your incoming water pressure determine how full and how fast the storage tank will be filled up.
The stronger your input water pressure, the faster and fuller the tank can fill. If water pressure is low,
the tank will fill slower and will not fill up to its full capacity.
For a Non-pumped RO system:
The 4 gallon tank* will fill up according to your input water pressure as follows:
Input 70+ psi —> tank fills 3.1 gallon ( almost 100% full )
Input 60 psi —> tank fills 2.8 gallon ( about 88% full )
Input 50 psi —> tank fills 2.5 gallon ( about 70% full )
Input 40 psi —> tank fills 1.9 gallon ( about 50% full )
The 14 gallon tank* will fill up according to your input water pressure as follows:
Input 70+ psi —> tank fills 9.7 gallon ( almost 100% full )
Input 60 psi —> tank fills 9.0 gallon ( about 88% full )
Input 50 psi —> tank fills 7.8 gallon ( about 70% full )
Input 40 psi —> tank fills 6.1 gallon ( about 50% full )
So, if your input water pressure is low, the tank will not fill up to full.
* 4-gal and 14-gal refer to tank’s total volume (air space & bladder). At 80-90psi, tank bladder’s capacity is around 3.2
gallons for 4-gal tank, and 10.3 gallons for 14-gal tank.
7) How Much Pressure Can RO Deliver to My Ice-Maker?
The RO’s delivery pressure depends on how full the tank is. The pressure is high when tank is full,
and drops when tank depletes. See charts below for 4gal tank and 14gal tank.
4-gallon tank’s delivery pressure:
3.0 gallon —> 50 psi output/delivery pressure (pressure inside tank)
2.5 gallon —> 36 psi
2.0 gallon —> 24 psi
1.5 gallon —> 18 psi
1.0 gallon —> 14 psi
0.5 gallon —> 10 psi
Tank empty —> 5 psi (pre-charged pressure)
