water slowly
22
Possible Causes
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.
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.
What To Do
• 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,
flow control, screen, prefilter, postfilter and battery
in the faucet base.
• This is normal.
• Completely drain system and allow to refill.
• Use sanitizing procedures.
• 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 your regular faucet.
• It takes 3–4 hours to fill the tank.
• 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.
• Replace Reverse Osmosis membrane cartridge, flow
control and battery in the faucet base.
