Tastes and Odors in Product Water
Possible Cause Solution
Carbon Post Filter is exhausted. Replace Filter.
There is foreign matter in Holding
Tank.
Clean, flush and sanitize the Holding Tank.
Replace filters.
Product water and Drain water lines
are reversed.
Correct plumbing.
Dissolved gases in feed water. Pre-treat feed water to remove gasses.
Increase in Product Water TDS. See High TDS in Product Water Section
Faucet Leaks or Drips
Possible Cause Solution Water leaks from faucet spout. Adjust faucet by turning the tee bar located
under the handle to provide a small amount of free play in the handle when shut off. Should this not
work, repair or replace the faucet. If leaks from beneath the handle, repair or replace the faucet.
What is an ASOV and what does it do?
ASOV is automatic shut-off valve. This valve allows your system to turn off the water supply, using
pressure from the pure water side of the system. It will turn off the water supply to the unit, whenever
there is sufficient pressure on the pure water side of your system. ASOV is a must. It saves water,
extends filter life, and improves the performance of your unit. As the storage tank fills the pressure
inside increases, when the pressure equals ½ to 2/3 your feed water pressure, the water to the
system is shut off. No waste. Since you subtract the storage pressure from the operating pressure,
the storage pressure needs be limited.
Cloudy ice cubes or milky colored water
Bad membrane - Use TDS Meter to check membrane. Replace membrane and sanitize when below
75% rejection.
Water supply High oxygen content or air bubbles – If filter cartridges are still new, it is normal and
should clear up in two weeks.
UV lamp compatibility
We have upgraded the UV lamp to a higher-quality brand (Philips) with 2 pins at each end since last
November 2011. If your system was purchased before Nov. 2011, a new UV transformer and a UV
wire are required. The transformer is available for sale at 123filter.com, under model # UVT11.
However, for old customers, we will offer $15 discount for the new transformer, and no charge on the
wire. Please go to 123filter.com and type in UVB11 and UVT11, then remark about the $15 discount
and the free wire.
After installation, the water out of the RO faucet is only a trickle. Is this normal?
Reverse osmosis is a very slow process. Water flow is only continual drop if bypassing the tank. With
the pre-pressured tank, the water out of the faucet will be about 7-10PSI (tank's pressure), which is
pretty strong flow. It takes about 2-3 hours to get the tank filled up, then the system will shut off
automatically and drain stops running.
