7) 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 pressure, you can add a Permeate Pump to your RO system.
8) Feeding Multiple Outlets:
Feeding the filtered water to multiple outlets is do-able. 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.
9) Insufficient Water Pressure – Problems with Non-Pump RO Systems:
The 3 most common problems caused by low input water pressure:
1) Tank does not fill up, get little water from tank
2) Sluggish flow at the dispensing faucet
3) RO makes water slower than the claimed GPD
If you experience these problems, Please check your input water pressure as the first step. This will often
solve the above listed problems.
10) How to Test Your Water Pressure:
Get a water pressure gauge that adapts onto your sink or garden faucet (from hardware store),
attach gauge onto faucet, turn water on to FULL, then take a reading.
For some areas, water pressure is lower during the day and higher at night when less people are using
water. So to get an accurate average, take several measurements at different times of the day and average
them out.
