LOW WATER PRESSURE FROM DISPENSING FAUCET
Possible Cause
Air Pressure in Holding Tank is incorrect.
This is the #1 reason for low flow from Reverse Osmosis Faucet.
Carbon Post Filter is clogged.
Heavy water use. Holding Tank is empty.
Low Water Production.
PRODUCT WATER IS HIGH IN TOTAL DISSOLVED SOLIDS (TDS)
Possible Cause
Clogged Pre-filter.
Low incoming water pressure.
Reverse Osmosis membrane is expended.
Product water and drain water lines are reversed.
No water to drain. Drain Flow Restrictor is clogged.
No water to drain. Air Gap Faucet is clogged.
The Automatic Shut-Off Valve is not closing.
New Carbon Post-filter has not been rinsed completely.
The incoming feed water TDS has increased.
FAUCET CONNECT FITTINGS LEAK
Possible Cause
Water leaks from faucet spout.
Leaks from connection to the faucet.
WFRO60X-1
Solution
Ensure the faucet spout is properly seated. Repair or replace the faucet.
Check and fix compression fittings to faucet. Repair or replace the faucet.
Turn off the cold water shut-off valve to the Filter System to release pressure in the System.
Loosen and remove the Compression Nut on the Faucet for Filtered Water Stem. Check the 1/4" Plastic
Tubing to see if it is cut squarely. Make sure the 3/8" Plastic Tubing is placed firmly into the end of the
Faucet Stem; retighten the Compression Nut securely by hand; then tighten 1/2 turn with an adjustable
wrench. Make sure tube insert is inside the tubing and the ferrule is in proper orientation. Turn the cold
water shut-off valve back on and turn on the Faucet for Filtered Water.
Solution
Open faucet and empty water from holding tank. Shut off feed water to system and
remove holding tank from under sink (the tank is easier to work on).
Locate the air valve stem (just like on a car or bicycle tire) and add air. If there is 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 5 - 7 PSI.
Re-install the tank under the sink, turn on the feed supply to the system and allow the
tank to fill.
R eplace Post Filter with DuPont model number WFQTC30001.
Allow Holding Tank to refill.
See previous section on Low Quantity of Water From Holding Tank.
Solution
Replace Pre-Filter with DuPont model number WFQTC30001
Incoming water pressure must be above 40 PSI. Install a Booster Pump or Permeate Pump.
If Membrane life is unusually short, find and correct the problem. (Average life is 1 - 2 years.)
Replace RO Membrane.
Correct plumbing according to installation instructions.
Remove tubing from membrane drain port, cut 1" length off end of tubing and add new restrictor.
Remove faucet body from faucet base and disconnect air gap ¼" tubing. Ensure there are no
obstructions – clear them out. Replace Air Gap Faucet.Remove faucet body from faucet base and
disconnect drain 3/8" tubing. Ensure the drain connector is properly aligned with the hole in the
drain pipe. Ensure there are no obstructions – clear them out.
Repair or replace Automatic Shut-Off Valve. Refer to maintenance section.
Drain Holding Tank twice to rinse new Carbon Post-filter.TDS.
An increase in feed water TDS will also give an increase in Product Water TDS.
