Possible Causes Solution
Trouble Shooting Guide - Reverse Osmosis Systems
Problems with Start-Up
&/or Filter Replacements
No water after installing system
No water after replacing filters,
in-line filter, &/or membrane
Problem - Leaks
Connections & Tubing
Any or All Leaks
Leaks at any of the
Tubing Connections:
See colors below:
Red - Incoming Supply
Blue - to Dispenser
Yellow - to Tank
Black - to Drain
Leak at FACTORY INSTALLED
fittings
Leak at plastic compression
fitting at UV Module
(option, if applicanle)
Leak at Inlet Water Supply Con-
nection
Problem Leaks - Faucet
Leak at the supplied faucet spout
Leak at the supplied faucet base
by handle (brass “T”)
Leak at the connection to supplied
faucet
Leak at another Mfg’s faucet or
connection to another device
Water running out of Air Gap adap-
tor of faucet
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
Filters amd membrane placed in the
wrong order
The interconnection between the inlet,
outlet, drain and tank lines can cause
air in the unit at the shutoff valve. Air
in lines, and at this valve, will not allow
RO 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
Excessive pressure or pressure
surges above 75 PSI
Various causes to inspect
See the Following;
•If cut, is the tubing cut with a straight
end to grab squarely?
•Is the tubing inserted completely into
fitting?
•Broken collect or fitting
•Is there a problem with the collet and
the quick-connect fitting?
•Tubing incorrectly removed
•Damaged in shipping,handling, and/
or delivery
Same as above
Damaged in shipping,handling, and/
or delivery
Various causes to inspect.
Angle Stop valve may not be appli-
cable or installed correctly
Spout needs to be re-inserted
O-ring at inserted brass piece or “T”
that holds and operates handle
Compression fitting & other connec-
tions need to be properly made
All connections need to be properly
made
Black 1/4” & 3/8” tubing misinstalled
or backwards
Drain saddle not allowing water to
drain into trap properly
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. Fol-
low instructions for proper start-up
Make sure membrane is in middle, Stage 2 and filters are in correct locations
Air in Lines “Burping Procedure”
REPEAT AS NEEDED.
Then close the dispenser, open tank valve, only open (if applicable) water
supply to other connected devices once and only 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 accurate
(0-20) gauge Empty tank and adjust (if needed) using 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
Pressure reducing valve (PRV) at main water supply to maintain pres-
sure at or below 75 PSI or the addition of a Pressure Limiting Valve
(item# FMP-60) on the inlet tube prior to the point of use unit
•Follow instructions for Connection of Tubing.
Access the filter unit, remove tubing by depressing the collet and pulling
tubing out. Using a utility razor knife, squarely cut 1/2” off tubing from the
end. Make sure end of tubing is not flattened Reinsert the tubing into the
fitting as far as possible. Check for leaks.
•Tug on tubing (do not pull hard) to check fitting and the integrity of the
connection
•Upon inspection, prior to install or a result of proper start-up and inspec-
tion and fitting is damaged,
Replace simple part (call for proper fitting part)
Same as above
Replace simple part (item# fc-uv-jaco)
•Check connections and/or correct.
•Follow the inlet supply water instructions in this manual and/or install
the preferred inlet connection
•Spout pulls out from faucet body that’s why it swivels. Spout has 2 o-
rings at base and is inserted completely into bottom of body to prevent
leaking.
•Replace the supplied faucet (item# depends on any finish option)
•Check connections at various locations and re-connect, re-insert,
tighten and/or correct.
•Consult with Mfg of other product and/or installer to check connections
at various locations and reconnect and/or correct.
Follow proper instructions for Air Gap installation and connections
Check hole for proper draining and proper drain saddle installation
Check for proper drain location
