TDS Meter – How to Test Your Water Quality:

The TDS meter is used to test your water’s quality before and after installing the RO system. It can also tell you when the membrane needs to be changed.

Please follow instructions below:

  • Use 2 clean glasses, fill one glass with Tap water, and another glass with Product (filtered) water (rinse this glass with filtered water several times to get an accurate reading). Read more

Basic Terms for Reverse Osmosis System

Terminology:

  • RO= Reverse Osmosis
  • GPD = Gallons per Day (flow rate)
  • PSI = Pounds per Square Inch (pressure)
  • TDS = Total Dissolved Solids (contaminants) Read more

How to Choose the Right Reverse Osmosis Model?

Choosing the right RO model depends on your incoming water pressure. If you are using city water, RO-45 and RO-90 are the suggested models. If you are using well water, RO-PERM and RO-PUMP are the suggested models.

Please see below for each individual model’s information:

RO-45 & RO-90 models:

  • Water pressure: Works best with 40psi pressure or higher. Read more

What is the Difference between TFC and CTA membranes?

TFC membranes are bacteria resistant and it has a higher removal rate of total dissolved solids compared to CTA membranes. We strongly recommend using TFC membrane for purifying drinking water.

CTA membranes need chlorine to protect itself from damaging molds and bacteria. CTA membranes should only be used in applications where water is chlorinated. We do not recommend using CTA membranes filtering water sources that are non-chlorinated (wells).

What is the Difference Between Reverse Osmosis Water and Distilled Water?

RO water is comparable (or better) than distilled water. Distillation systems are not designed to remove chlorine and other chemicals completely from water. Organics such as herbicides and pesticides, with boiling points lower than 100°C, cannot be removed efficiently and can actually become concentrated in the product water.

Distilled water systems can be more costly to maintain than RO systems. It needs to operate using electricity for water heating and some systems will waste 5 gallons of water (or more) to produce one gallon of pure water. Read more

What is the Difference Between Reverse Osmosis Water and Deionized Water?

RO systems are designed to remove 90-95% of total dissolved solids or higher. If you would like your drinking water to contain TDS as low as possible, you can consider adding a DI (deionized) filter to a RO system as a post filter. A DI filter can remove remaining total dissolve solids after a RO system through ion exchange process.

We do not recommend installing a DI as a stand-alone or pre-treatment filter for a RO system. DI filters are higher in cost and if you don’t first use RO system to remove most of the total dissolved solids in water, you may need to replace DI filter on a weekly or monthly bases. Read more

How to Move a RO System to New Home

Please follow the steps below in moving your RO system:

  1. Turn OFF the feed water supply to the RO unit.
  2. Turn ON the RO faucet (lift black lever into locked position) to drain out all pure water from the tank. 
  3. Once the tank has fully emptied, remove the YELLOW Line from the tank’s ball valve. Once the yellow tubing is removed, please turn off RO faucet. Read more

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

The Lead-Reduction Carbon filter (FI-PB1) is recommended to be added to your R.O. system as a Stage-6 Specialty Filter.  Add this filter between the Stage-5 filter and the dispensing faucet as shown in the Diagram below. 

Some extra ¼” tubing are provided in case you need to make a longer connection.

  • Step 1:  Put the filter cartridge into the Housing (remove cartridge wrapping). Close the housing cap tightly. Read more

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
