LOW WATER PRESSURE FROM DISPENSING TAP
Possible Cause
Solution
Air Pressure in Holding Tank is incorrect.
T
This is the #1 reason for low flow from Reverse Osmosis Tap.
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.
Carbon Post Filter is clogged.
Replace Post Filter with model number PTL-CB
Heavy water use. Holding Tank is empty.
Allow Holding Tank to refill.
Low Water Production.
See previous section on Low Quantity of Water From Holding Tank.
Possible Cause
Solution
Clogged Pre-filter.
Replace Pre-Filter with model number PTL-CB
Low incoming water pressure.
Incoming water pressure must be above 40 PSI. Install a Booster Pump or Permeate Pump.
Reverse Osmosis membrane is expended.
If Membrane life is unusually short, find and correct the problem.
Replace PTL-RO Membrane after 18 months.
Product water and drain water lines are reversed.
Correct plumbing according to installation instructions.
No water to drain. Drain Flow Restrictor is clogged.
Remove tubing from membrane drain port, cut 1” length off end of tubing and add new restrictor.
No water to drain. Air Gap Tap is clogged.
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.
New Carbon Post-filter has not been rinsed completely.
Drain Holding Tank twice to rinse new Carbon Post-filter.TDS.
The incoming feed water TDS has increased.
An increase in feed water TDS will also give an increase in Product Water TDS.
PRODUCT WATER IS HIGH IN TOTAL DISSOLVED SOLIDS (TDS)
Possible Cause
Solution
Water leaks from tap spout.
Ensure the tap spout is properly seated. Repair or replace the tap.
Leaks from connection to the tap.
Check and fix compression fittings to tap. Repair or replace the tap.
