TROUBLE SHOOTING
Problem
Cause Solution
1. Low/Slow Production
Low Water Pressure
Assure a minimum of 40 psi incoming water pressure.
Watts sells a booster pump if home water pressure is
low. Make sure water supply is turned on and Adapta
Valve
is
all
the
way
open.
Crimps in tubing
Check tubing and straighten or replace as necessary.
Clogged
pre-
fi
lters
Replace pre-
fi
lters.
Fouled membrane Replace membrane and clean
fl
ow restrictor.
Tank valve closed Open valve on storage tank
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
during normal use within 1-2 weeks. If condition reoccurs
after
fi
lter change, drain tank 1 to 2 times.
3. Water constantly
Low water pressure
See #1 Above
running/unit will not
shut off
Fouled membrane
Replace membrane
High water pressure
Check incoming water pressure to make sure it does not
exceed 100psi. A pressure relief valve may be necessary.
High air pressure in tank
Empty storage tank of water. Set tank air pressure to 5
psi.
See
Page
15.
4. Noise from faucet or drain
Air gap faucet
Inherent sound with air-gap faucets.
Location of drain saddle
See diagram for proper location of drain saddle.
Higher capacity membrane
Normal with high capacity membrane
High water pressure
Check incoming water pressure to make sure it does not
exceed 100psi. A presser relief valve may be necessary.
5. Faucet leaks from
Crimp or loop in drain line
Straighten black 3/8 drain tube. Cut off any excess tubing
the air gap feature
Drain tube clogged/restricted
Caused from dishwasher or garbage disposal.
Disconnect the 3/8” black tube at the drain, clean the 3/8”
black tube out with a wire, then reconnect.
6. Small amount of water in
System just starting up
Normally it takes 6-10 hours to
fi
ll tank. Note: Low
storage tank
pressure and/or temperature can drastically reduce
production
rate.
Low water pressure
See #1 Above
Too much air in tank
Add air if below 5 psi and bleed if above 5 psi. Check
only when tank is empty of water. See Page 15.
7. Water leaks from the
Not properly tightened.
Tighten the bowl
fi
lter housing
Missing or kinked O-ring
Turn off the water supply. Release the pressure, remove
bowl and replace the O-ring. (p/n 113043). Make sure
the
O-ring
is
seated
in
the
fi
lter bowl properly before
reinstalling
the
fi
lter bowl.
