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 —> 36psi
  • 2.0 gallon —> 24 psi Read more

How to Add a Lead-Reduction Carbon (FI-PB1) Filter To Your R.O. System

How to Connect Two Storage Tanks To APEC RO System

The two storage tanks should be hooked up side-by-side in parallel. The RO system fills up both tanks simultaneously. When you dispense pure water, water is drawn from both tanks simultaneously.

See figure below for tank connection:

  1. Add T-fitting to divert output into 2 directions   
    • Between points B and Y is the pure water line (Yellow line). Read more

Bad Taste To RO-CTOP Pure Water

If you are experiencing a bad taste in the Pure Water, the RO Membrane or Stage 2 or 4 Carbon filter may be depleted and needs to be replaced. Please follow the steps below to determine if the membrane or stages 2 and 4 carbon filters needs to be replaced.

  • Fill up a clean cup of water from the RO Unit.
  • Take a Pure Water TDS reading with the supplied TDS Digital Meter that came with the RO unit. Read more

What to Do When Drain Water Runs All the Time

Our RO systems are designed to shut off automatically when the tank is full. When the RO fails to shut off after tank is full, drain water will continue to run, possibly depleting the pre-filters, the membrane, and costing high water bills.

If the drain water is running non stop, the input water pressure may be too low (below 40psi). Not enough pressure to shut off the RO at all,  check input water pressure. If pressure is below 40psi, you may need to switch to Booster-Pumped RO model. Read more

Why Does the Water From My RO System Seems Cloudy?

The water out of my RO system seems milky or cloudy, what is the reason for this issue?

This is generally caused by trapped air within the RO system. However, it will not affect the quality of your water. The cloudiness should disappear within a minute after water sits in a glass. This is a normal occurrence with a newly installed RO System or after a filter change. You can release the air from your RO system by draining the tank 1 to 2 more times or using RO makes humming noise air release instructions in your system manual (see below). Read more
