TROUBLESHOOTING

NOTE: If leaks persist, or if there are other leaks in the
processor, turn OFF water supply and call Technical
Support 800.942.1153 (US only)/630.307.3000.
Leaks Between Cartridge and Filter Housing
1. Turn OFF cold water supply to processor. CLOSE tank
valve. OPEN the application valve to relieve water
pressure.
2. Remove the cartridge, inspecting it for damage. Inspect
o-rings to make sure they are seated and clean.
3. Insert and twist the cartridge back into the filter housing.
4. Turn ON water supply. OPEN tank valve. CLOSE the
application valve after water begins to flow. If leaks
persist, call Technical Support.
Leak Between Tank Valve and Storage Tank
1. Turn OFF water supply to processor. OPEN the
application valve to drain storage tank. Run for three (3)
to five (5) minutes until water drips.
2. Remove tubing from tank valve by pressing the collar around
the fitting while pulling the tubing with your other hand.
3. Unscrew the tank valve from the storage tank.

4. Inspect the rubber seal inside the threaded area. Repair
or replace the valve as needed.
5. Thread the tank valve onto the top of the tank opening by
turning it clockwise until snug.
6. Wet the tubing and insert it 3/4" (1.9 cm) into the quick-
connect fitting.
7. Turn water supply ON and CLOSE the application valve.
8. Allow processor to pressurize for several hours and
check for leaks.
9. Check for leaks after tank is fully pressurized [one (1) to
three (3) hours]. If leak persists, call Technical Support .
Leaks at Quick-Connect Fittings
CAUTION: The 1/4" red tubing connected to the bottom
drain connection of the RO cartridge has a flow
restrictor installed. The processor will not
operate correctly if the restrictor is removed.
1. CLOSE tank valve, turn OFF cold water supply to the
processor, and OPEN the application valve.
2. Press collar around the quick-connect fitting while
pulling the tubing with your other hand.
3. Tubing should be cut squarely. Internal and external
burrs should be removed. Place a mark on tubing 5/8"
(1.6 cm) from end on 1/4" tubing or 3/4" (1.0 cm) from
end on 3/8" tubing.
4. Wet the end and insert tubing until the mark is flush with
the quick-connect fitting.
5. OPEN the cold water supply until it comes to a stop.
OPEN the tank valve and CLOSE the application valve. If
leaks persist, call Technical Support.
No Flow or Slow Flow from the Brine (Reject) Line (Less
than 6 fl. oz. or 180 mL per minute)
NOTE: Before checking brine (or reject) flow, make sure the
unit is producing water by turning the valve on the
storage tank OFF and OPENING the application valve.
Water should drip from valve.
1. Replace the prefilter cartridge according to the
"Changing the Cartridge Instructions" and recheck the
brine (or reject) flow rate.
2. If the prefilter cartridge is not at fault, the brine (or
reject) flow controller could be clogged. Call
Technical Support.
High TDS in Product Water
1. If high TDS (Total Dissolved Solids) is detected in the
blended water, the RO cartridge may need to be replaced
or the reject flow control tubing may be clogged. If this is
a new installation, call Technical Support.
2. Otherwise, draw 1 gal (3.8 L) of water from the unit. After
10 minutes, run water from the blended water port and
test the water again.
3. Determine when you last changed the RO cartridge and
call Technical Support.
