3. Low water pressure from dispensing faucet
CAUSE:
A Air pressure in holding tank is incorrect. This is
the #1 reason for low flow from reverse osmosis
system.
B Carbon post filter is clogged
C Holding tank valve is partially closed
D The faucet is out of adjustment of faulty.
E Heavy water use. Holding tank is empty.
F Low water production
4. Drain water overflows at the air gap faucet
CAUSE:
A Air gap is clogged
B Drain line is clogged
C Drain flow rate is too high
5. Product water is high in total dissolved solids (TDS)
CAUSE:
A Clogged pre-filters
B Low Incoming water pressure
C Reverse osmosis membrane is expanded
D Product water and drain water line are reversed
E No water to drain. Drain flow restrictor is
clogged.
F No water to drain. Air Gap faucet is clogged.
G The automatic shut-off is not closing
H New carbon post-filter has not been rinsed
completely
I The incoming feed water TDS has increased
CORRECTION:
Open faucet and empty water from holding tank. Shut
off feed water to system and remove holding tank
from under sink. Locate the air valve stem and add
air. If there's still water in the tank, continue to add air
until all the water is removed. Once all the water is
removed, continue to add air and pressurize to 8 psi.
Re-install the tank under the sink, turn on the feed
water supply to the system and allow the tank to fill.
Replace post filter.
Open tank ball valve fully.
Repair or replace the faucet
Allow holding tank to refill for about an hour or so
before using the water.
See "Not enough water from holding tank" for
troubleshoot.
CORRECTION:
Clear Air Gap
Clear Tubing
Replace flow restrictor
CORRECTION:
Replace Filter
Incoming water pressure must be above 40 psi. Install
a booster pump or permeate pump
If membrane life is unusually short, check the TDS
level of incoming water to see if it exceed the range
of recommended operating condition. Pretreatment
may be needed if the incoming TDS level is too high.
An average life of membrane should be around 2 - 3
years. Replace the RO membrane
Check the connection and correct plumbing
Replace drain flow restrictor
Clear or replace air gap faucet
Repair or replace automatic shut-off valve
Drain holding tank twice to rinse new carbon post-
filter
An increase in feed water TDS will also give an
increase in product water TDS
