3) Water Pressure – The Most Important Factor!
RO systems run on water pressure. Therefore your water pressure has the most direct effect on how
well your RO will perform. With sufficient water pressure (85 psi max.), your RO system will function well,
give high output with high removal rate, and fill up the storage tank quickly.
4) TDS Meter (Option) – How to Test Your Water Quality:
The TDS meter is used to test your water’s quality before and after the RO system. It also tells you when the
membrane needs to be changed.
Please follow instructions below:
Use 2 clean glasses, fill one glass with Tap water, fill the other glass with Product (filtered) water
(rinse this glass with filtered water several times to get an accurate reading). Remove the Sensor cap on the
TDS meter and rinse the meter sensor with filtered water several times, then Turn on the meter.
The meter will show “000” reading on its screen. Place the TDS meter into the Product water. Record Prod-
uct water’s TDS reading. Then do the same for the Tap water. Record the Tap water’s reading. Compare the
2 readings.
The Product water’s TDS should be about 3%-10% of your Tap water’s TDS. This is a normal range.
For example:
Your Tap water’s TDS: 100 ppm
Your Product water’s TDS should read within: 10% of 100ppm => 10ppm
This means that with 100 ppm input, the RO system has removed 90% of the contaminants (TDS)
from the source, leaving only 10% (10 ppm) residual TDS in the Product water. This is a normal
range. Which means the RO membrane is in good condition.
If your Product water TDS reads less than 10%, that is a very good and normal reading.
You should test your water once or twice a year to monitor the membrane condition. As the membrane gets
depleted overtime, its rejection capacity will decrease. When this happens, the TDS in the Product water will
increase.
When your Product water TDS creeps up to 15%- 20% of input water’s TDS, it’s time to replace the
membrane.
5) How Long Does It Take to Fill Tank?
Depending on your water pressure, the standard tank will fill up in 2-3 hours. After the tank is filled, the RO
will shut off automatically.
Important!
Please TURN OFF the main cold water supply to the RO system when the unit is not in use
during a vacation or extended leave. During very cold or freezing weather conditions, please also TURN
OFF the main cold water supply and completely drain all of the water from the RO system and water
storage tank.
