TROUBLESHOOTING
CAUSE
1) WATER SUPPLY IS TURNED OFF.
2) NOT ENOUGH WATER PRESSURE TO SYSTEM.
3) PREFILTERS CLOGGED.
4) FLUSH VALVE ON UNIT IS IN THE OPEN
POSITION.
5) PUMP NOT WORKING
6) SOLENOID VALVE NOT WORKING
1) AIR IN SYSTEM
1) AIR GAP FAUCET
2) LOCATION OF DRAIN SADDLE
3) RESTRICTION IN DRAIN LINE
1) TANK BALL VALVE IS IN THE CLOSED
POSITION.
2) PREFILTERS ARE CLOGGED.
3) MEMBRANE IS FOULED.
4) NO AIR PRESSURE IN TANK.
5) CHECK VALVE ON PRODUCT SIDE NOT
HOLDING.
1) LOW WATER PRESSURE
2) CRIMPS IN TUBING
3) CLOGGED PRE-FILTERS
4) FOULED MEMBRANE
1) POST CARBON IS DEPLETED
2) FOULED MEMBRANE
3) SANITIZER NOT FLUSHED OUT
1) CLOGGED FLOW RESTRICTOR
1) TUBING CONNECTED INCORRECTLY
2) MEMBRANE FAILURE
1) AUTO SHUTOFF NOT CLOSING.
2) CHECK VALVE ON PRODUCT SIDE NOT
HOLDING
1) FITTINGS ARE NOT TIGHTENED
2) MISSING O-RINGS
3) MISALIGNMENT OF HOLE IN DRAIN
SADDLE
CORRECTION
1) TURN WATER SUPPLY ON.
2) CHECK TO MAKE SURE FEED VALVE IS NOT CLOGGED.
1) CHECK FEED WATER PRESSURE. MUST BE AT LEAST 10PSI.
1) CHANGE PREFILTERS.
1) CLOSE THE FLUSH VALVE.
1) MAKE SURE TRANSFORMER IS PLUGGED TO ELECTRICAL OUTLET
2) REPLACE TRANSFORMER IF BURNED
3) REPLACE HI AND/OR LOW PRESSURE SWITCHES
1) REPLACE SOLENOID VALVE
1) AIR IN SYSTEM IS A NORMAL OCCURRENCE WITH
INITIAL STARTUP OF THE RO SYSTEM. THIS MILKY
LOOK DISAPPEARS DURING NORMAL USE WITHIN 1 TO
2 WEEKS.
1) NORMAL WITH AIR GAP FAUCET
1) RELOCATE THE DRAIN TO HORIZONTAL
1) BLOCKAGE SOMETIMES CAUSED BY DEBRIS FROM
GARBAGE DISPOSAL OR DISHWASHER
1) OPEN THE TANK BALL VALVE.
1) CHANGE PREFILTERS.
1) CHANGE MEMBRANE.
2) FIND REASON FOR FOULING. TO PREVENT FUTURE OC-
CURRENCE.
1) CHECK AIR PRESSURE IN TANK. MUST BE 8-10 PSI WHEN
COMPLETELY EMPTY OF WATER.
2) BLADDER IN TANK IS RUPTURED. TANK MUST BE RE-
PLACED WITH NEW ONE.
1) REPLACE CHECK VALVE ON UNIT.
1) MAKE SURE PUMP IS WORKING
1) MAKE SURE TUBING IS STRAIGHT
1) REPLACE PRE-FILTERS
1) REPLACE MEMBRANE
1) REPLACE POST CARBON
1) CHANGE MEMBRANE.
2) FIND REASON FOR FOULING. TO PREVENT FUTURE OC-
CURRENCE.
1) DRAIN STORAGE TANK AND REFILL OVERNIGHT
1) REPLACE FLOW RESTRICTOR
1) MAKE SURE DRAIN AND PRODUCT LINES ARE CON-
NECTED PROPERLY.
1) CHLORINE MAY HAVE PASSED THROUGH TO MEMBRANE.
REPLACE MEMBRANE AND CHANGE PREFILTERS.
2) MEMBRANE MISHANDLED OR STORED IMPROPERLY.
REPLACE MEMBRANE.
1) REPLACE AUTO SHUTOFF.
1) REPLACE CHECK VALVE.
1) TIGHTEN FITTINGS AS NECESSARY
1) CONTACT LOCAL DEALER
1) REALIGN DRAIN SADDLE
