6) How Full Can My Tank Fill Up?
Your water pressure and temperature will 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 )
So, if your input water pressure is low, the tank will not fill up to full.
* 4-gal refers to tank’s total volume (air space & bladder). At 80-90psi, tank bladder’s capacity is around 3.2 gallons.
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 chart below for 4-gallon 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)
8) Ice-Maker Inlet Pressure Requirement:
If your ice-maker requires a minimum input water pressure of 20-30psi, you need to have at least 50+psi
input water pressure going into your non-pump RO system. If your water pressure is under 50psi, the tank
will not fill up enough, and the delivery pressure to your ice-maker may be sluggish and unstable. To boost
output pure water pressure, you can add a Permeate Pump to your RO system.
9) Feeding Multiple Outlets:
Feeding the filtered water to multiple outlets is doable. The key is choosing the right RO model that fits your
house’s water pressure level. This model should fill up the tank quickly and fully. A frequently full tank will
then provide good delivery pressure to feed the multiple outlets in your house.
We suggest limiting output points to no more than 3 outlets. Total tubing distance should be within 40 ft.
horizontal and 15 ft. vertical from the RO system (more or less).
