Troubleshooting and Solutions Guide
Symptom
Posible Cause
Solution
NO WATER COMING OUT
OF THE SYSTEM
Feed valve is closed.
Open the Feed Valve.
There is not enough pressure for the
membrane to produce water.
Make sure booster pump, low pressure & cut off switch are working
properly . If damaged correct or replace.
PRODUCT WATER
IS HIGH IN TOTAL
DISSOLVED SOLIDS
(TDS)
Clogged Prefilter.
Replace Filter.
Low incoming water pressure.
Your booster pump may not be operating properly.
If damaged correct or replace.
Reverse Osmosis Membrane is not correctly
sealed in Membrane Housing.
Check that RO Membrane is correctly installed and check
the membrane housing for internal leaks that cause
the rejection and production water to mix.
Reverse Osmosis membrane exhausted.
If Membrane life is unusually short, find and correct the problem.
(Average life is 2 - 3 years) Replace RO Membrane.
Product water and drain water lines are reversed.
Correct plumbing.
No water to drain. Drain Flow Restrictor is clogged.
Replace Drain Flow Restrictor.
The Solenoid Valve does not close when
the Holding Tank is full
Check for blockage inside the solenoid valve and check if electrical
current is reaching the high pressure swicth or level switch.
Carbon postfilter has not been rinsed enough.
Drain the holding tank to allow the fine particles of the new
carbon block cartridge to be expelled.
The incoming feed water TDS has increased.
An increase in feed water TDS will also give an increase in
Product Water TDS.
TASTES AND ODORS
IN PRODUCT WATER
Carbon Post Filter is exhausted.
Replace the Carbon Block Filter.
There is foreign matter in Holding Tank.
Clean, flush and sanitize the Holding Tank. Replace filters.
Product water and Drain water lines are reversed.
Correct plumbing.
Dissolved gases in feed water.
Pre-treat feed water to remove gases.
LOW WATER
PRESSURE FROM
DISPENSING FAUCET
Air Pressure in Holding Tank is incorrect.
Open faucet to empty all the water from holding tank
and check the air pressure level.
Carbon Post Filter is clogged.
Replace the Carbon Block Filter.
Holding Tank Valve is partially closed.
Open Holding Tank Valve.
The Faucet is out of adjustment or faulty.
Repair or replace Faucet.
Heavy water use.
Allow Holding Tank to refill.
Holding Tank is empty.
