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. 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. Tiny frozen bubbles. System is still new This 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.
Sudden drop in RO water production: There are a few potential factors causing
the problem?
•
Feed water valve is plugged or closed.
•
Sediment/Carbon prefilter or Carbon Post Filter is clogged.
•
Low incoming water pressure.
