LOW WATER PRESSURE FROM DISPENSING TAP
Possible Cause
Air Pressure in Holding Tank is incorrect.
T T his is the #1 reason for low flow from Reverse Osmosis Tap.
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 Tap is clogged.
New Carbon Post-filter has not been rinsed completely.
The incoming feed water TDS has increased.
Possible Cause
Water leaks from tap spout.
Leaks from connection to the tap.
Solution
Ensure the tap spout is properly seated. Repair or replace the tap.
Check and fix compression fittings to tap. Repair or replace the tap.
Solution
Open tap 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.
Replace Post Filter with model number PTL-CB
Allow Holding Tank to refill.
See previous section on Low Quantity of Water From Holding Tank.
Solution
Replace Pre-Filter with model number PTL-CB
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.
Replace PTL-RO Membrane after 18 months.
Correct plumbing according to installation instructions.
Remove tubing from membrane drain port, cut 1" length off end of tubing and add new restrictor.
Remove tap body from tap base and disconnect air gap ¼" tubing. Ensure there are no
obstructions – clear them out. Replace Air Gap Tap.Remove tap body from tap 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.
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.
