16
Possible Causes
Air in system after installation.
The ppm of chlorine in
your water supply exceeds
maximum limits and has
destroyed the Reverse
Osmosis membrane.
The prefilter is no longer
reducing chlorine from the
water supply.
High quality product water
may have a different taste than
what you're used to.
Low water usage.
Contamination in product water
storage.
Prefilter and postfilter need to
be changed.
Drain side of faucet air gap
(3/8" tubing) plugged, restricted
or incorrectly connected to the
drain.
This is normal.
Water supply to the Reverse
Osmosis system not within
specifications.
Prefilter cartridge plugged with
sediments.
Reverse Osmosis membrane
plugged with sediments.
Water supply valve not turned
on.
Improperly installed
Sink drain, drain water from
system.
Faucet air gap drain water
flowing through the faucet air
gap. This may be associated
with high pressure water
supply, generally 80 psi or
greater.
What To Do
Will go away after it runs for a while.
If the water supply contains more than 2.0 ppm of chlorine,
additional filtering of the water supply to the Reverse Osmosis is
needed. Correct this condition before doing maintenance on the
Reverse Osmosis system.
Replace the Reverse Osmosis membrane cartridge, prefilter,
postfilter and battery in the faucet handle.
This is normal.
Completely drain the system and allow to refill.
Use sanitizing procedure.
Replace the prefilter and postfilter. Sanitize system.
Inspect and eliminate restriction or plug. It is important that there
are no dips, loops or low spots in the drain line from the faucet air
gap to the drain pipe. Refer to Installation Instructions for proper
drain connection. If drain line adapter was used as the drain point,
periodic inspection/cleaning is recommended.
Water flow rate will be lower than a regular faucet.
Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis system.
Replace the prefilter. If rate does not increase, replace the postfilter,
Reverse Osmosis membrane cartridge and battery in the faucet
handle.
Replace Reverse Osmosis membrane cartridge and battery in the
faucet handle.
Turn water supply valve on.
Reinstall. See Installation Instructions.
This is normal.
Drain line can be installed to an alternate drain, such as a basement
drain.
Install a pressure regulator in the house water supply to reduce the
pressure below 80 psi.
