8. TROUBLESHOOTING

Problem
Fitting leak
Drain saddle leak
Filter housing leak
Purified water flow
rate is lower than
normal
Purified water runs
normally for a few
seconds, then slows
down to a trickle (in
a pressure tank
equipped system)
The system keeps
switching on and off
and will not stop
The system will not
switch on
The system will not

Possible cause
Tube is not connected
tightly
Drain saddle is not
installed correctly
O-ring seal is missing
or misaligned
Filter bowl is not
tightened
Low feed water
pressure
Soiled prefilters
Soiled membranes
Bent flexible tube
Deflated pressure tank
bladder
Surges in feed water
pressure just above
low pressure switch
setting
Feed valve or main
shutoff valve is closed
Low pressure switch
failure
High pressure switch
failure
Soiled membranes
Method of handling
Remove and reinstall the tube
properly.
Reinstall drain saddle as described in
paragraph 4.2 of this manual.
Check that the O-ring seal is correctly
seated in circular groove inside bowl.
Hand tighten the housing till snug.
If feed water operating pressure is
lower than 2 bar, eliminate any
upstream pressure drop and consider
installing pressure booster pump.
Replace prefilters.
Replace membranes.
Inspect the tubing and straighten if
necessary.
Pressure tank must drain empty when
purified water tap is open and the RO
system is unplugged. If pressure in the
bladder of empty tank is less than
0,4 bar, inflate to required pressure.
Eliminate pressure surges. Check
supply water piping for clogs and other
obstructions and eliminate if present.
Open all valves on supply water pipes.
Check for clogs/obstruction.
Replace low pressure switch. Verify
proper electrical contact.
Replace high pressure switch. Verify
proper electrical contact.
Replace membranes.
