Trouble Shooting
PROBLEM CAUSE SOLUTIONS
1. Low/Slow Production Low water pressure
Crimps in tubing
Clogged pre-filters
Fouled membrane
Assure a minimum of 40 psi incoming water pressure.
Make sure water supply is turned on and Adapta valve is
all the way open
check tubing and straighten or repair as necessary
replace pre-filters
replace membrane and flow restrictor.
2. Milky colored water Air in System Air in the system is a normal occurrence with initial start
up of the RO system. This milky look will disappear dur-
ing normal use within 1-2 weeks. If condition reoccurs
after filter changes, drain tank 1 to 2 times.
3. Water constantly running/ unit
will not shut off
Low water pressure
Crimp in supply tube
High water pressure
High pressure in
See #1 above
Check tubing and straighten or repair.
Check incoming water pressure to make sure it does not
exceed 80 psi. A pressure relief valve may be neces-
sary.
Empty storage tank of water. Set tank air pressure to 5
psi. See previous page.
4. Noise from faucet or drain Air gap faucet
Location of drain saddle
Restriction in drain tube
High water pressure
Inherent sound with air-gap faucets
See diagram for proper location of drain saddle.
Clear blockage sometimes caused by debris from garbage
disposal or dishwasher.
Pressure regulator required if pressure exceeds 80 psi
5. Faucet leaks Crimp in drain line
Restriction in drain line
Drain tube clogged
Check tubing.
Straighten all drain lines. Clear blockage. Cut off any
excess tubing.
Caused from dishwasher or garbage disposal. Disconnect
the 3/8” black line at the drain, clean the 3/8” black line
out with a wire, then reconnect. Blowing air through the
line will not always remove the clog.
6. Small amount of water in stor-
age tank
System just starting up
Low water pressure
Excessive air in tank
bladder
Normally it takes 4-6 hours to fill tank. Note: low pres-
sure and/or temperature can drastically reduce produc-
tion rate.
See # 1 above
Tank pressure is set at the factory and should be 5 psi
when empty. Add if below 5 psi and bleed if above 5
psi. Check only when tank is empty. See previous
page.
7. Water leaks from the
white filter housing
Not properly tightened
Kinked O-ring
Tighten the housing
Turn off the water supply and release the pressure.
Replace the O-ring if necessary. Then lubricate it and
make sure the O-ring is seated in the filter housing prop-
erly before reinstalling the filter housing.
