Problem: Pure water flow rate is too low.
1. Possible Cause: If the reject water flow rate is also too low, the 5 micron sediment filter,
active carbon block filter and RO membrane could be dirty.
Solution: Check the 5 micron sediment filter and active carbon block filter and replace
accordingly. Flush the RO membrane and/or replace accordingly.
2. Possible Cause: The mains water pressure may have dropped.
Solution: Check with your water supplier and install a booster pump if required.
3. Possible Cause: There may be a kink in the RO tubing.
Solution: Check the RO tubing and rectify any kinks accordingly
4. Possible Cause: A leak may have occurred somewhere in the installation.
Solution: Check for leaks and rectify accordingly.
5. Possible Cause: Ambient temperature may have dropped.
Solution: If necessary move the RO system to a location with a higher ambient
temperature.
FAQ
Can I upgrade my V
2
Pure RO System to a higher GPD (gallon per day) water
capacity by just installing a different RO membrane with a higher GPD capacity?
No. In each RO unit the flow restrictor is specific to the RO membrane that is supplied with
the unit. This flow restrictor determines an RO unit’s GPD production and prevents
overburdening the membrane. To increase your GPD production, a larger rated RO membrane
along with the correct size of flow restrictor must be installed.
Is there any way to increase the removal efficiency of my V
2
Pure RO System?
Yes. Although the RO membrane removes approx. 93-98% of contaminants in the water, the
removal efficiency of the RO system can be further enhanced by installing the V
2
Pure De-
Ionising Pod in the RO system. This is simply installed after the RO membrane and will help
ensure the removal of any remaining contaminants that may have passed through the RO
membrane, providing optimum water quality for your aquarium.
Can a TDS Monitor be installed in my V
2
Pure RO System
Yes. A V
2
Pure TDS (Total Dissolved Solids) Monitor (sold separately order code 5857) can be
simply installed in-line on the RO system to measure and provide a highly accurate ‘real-time’
display of total dissolved solids levels in the water, before and after going through the V
2
Pure
RO membrane. This will detect any elevated TDS levels within the pure water exiting the RO
membrane indicating that the RO membrane and other components (5 micron sediment filter
cartridge and active carbon block filter cartridge) are no longer operating at an optimum level
and need to be replaced or flushed accordingly.
Can a booster pump be Incorporated into my V
2
Pure RO System?
Yes. To achieve the optimum efficiency of the V
2
Pure RO System, mains water pressures should
be at least (50 psi/3.5 bar approx). In some areas, household water pressures can drop below
this so, by simply installing a V
2
Pure Booster Pump in-line between your cold water mains
supply and the V
2
Pure RO System, the RO membrane pressure can be increased and the unit
can work at optimum efficiency.
