Troubleshooting Tips
Save time and money! Review the charts on the following
pages first and you may not need to call for service.
Problem
Sounds you might hear
Water has air bubbles
and is cloudy
Chlorine taste and/or
odor in the Reverse
Osmosis product water
Other taste and/or odor
Water leaking from
faucet air gap hole
System makes product
water slowly
18
Possible Causes
Running water from the unit
to a drain.
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
removing 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 and/or
the Reverse Osmosis cartridge
needs to be changed.
Drain side of faucet air gap
(3/8² tubing) plugged, restricted
or incorrectly connected to the
drain point.
This is normal.
Water supply to the Reverse
Osmosis system not within
specifications.
Prefilter cartridge plugged
with sediments and/or the
Reverse Osmosis cartridge
plugged with sediments.
What To Do
• This is normal.
• Will go away after water 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,
control, screen, prefilter and postfilter
• This is normal.
• Completely drain system and allow to refill.
• Use sanitizing procedures.
• Replace the prefilter and postfilter. If taste and odor
persists, replace the Reverse Osmosis cartridge, flow
control and screen.
• 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 the
Filtration Drain Connection Installations section, 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 your 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 cartridge, flow control,
and screen.
