Problems
with Start-Up &/or
Filter Replacements
No water after installing the
system
No water after replacing
filters, in-line filters, &/or
membranes
Leak at fittings and tubing
Leak at dispenser or air gap
Leak at housings
Electrical (if applicable)
Water flow and quantity
issues
Water quality issues
Drain issues
Improper start-up of the unit upon
installation or filter replacement
It takes hours after a proper install
to have a full tank for use
The interconnection between the in-
let, outlet, drain and tank lines can
cause air in the unit at the RSR con-
trol valve. Air in lines, and at this
valve, will not allow R.O. to function
properly.
Tank valve is closed
Tank pressure is off,
Tank pressure too low or too high
Connections of tubing incorrect
Drain line and/or drain hole restricted
or clogged
Saddle tapping valve piercing not
complete, if applicable
Various Possible Causes
******************************
Please review this comprehensive
troubleshooting guide
to determine the cause
Start with the start-up procedures and follow them as
if the unit was just installed
Make sure start-up was performed correctly and wait
for tank to fill. Follow instructions for proper start-up
Air in Lines “Burping Procedure”
Close the tank valve,
Close (if applicable) water supply to other devices that
may be connected to this unit,
Open and lock dispenser (observe sputtering from dis-
penser or a slow drip).
Rotate the entire unit 90° degrees clockwise and hold in
vertical position, after a minute return unit back to hori-
zontal position ,
Then rotate the entire unit 90° degrees counterclock-
wise and hold in that vertical position, after one minute
return unit back to horizontal position,
Water should drip at a steady flow (about 1-11/2 gallons
per hour) without sputtering or any gurgling sound.
REPEAT AS NEEDED.
Then close the dispenser, open tank valve, only open (if
applicable) water supply to other connected devices once
andonly once the tank has filled completely.
Open valve, in line or parallel with yellow tubing, close
other devices and begin proper start-up procedure.
The tank air pressure should be 5-7 psi without water in
tank for proper operation. Pressure variances due to
higher elevations may occur. Under or over-inflation will
prevent proper operation of system. Check with accu-
rate (0-20) gauge Empty tank and adjust (if needed) us-
ing a bicycle or sports ball pump. Begin proper start-up
procedure
Inspect and follow all connections of all tubing
Follow proper instructions for Air Gap installation and
connections
Check hole for proper draining and proper drain saddle
installation
Check for proper drain location
Follow instructions to re-do piercing or use the
preferred method to make this connection
