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. Make sure
the O-ring is seated in the fi lter bowl properly before
reinstalling the fi lter bowl.
