TROUBLE SHOOTING
Problem Cause Solution
1. Low/Slow Production Low Water Pressure Assure a minimum of 40 psi incoming water pressure.
Premier sells a booster pump if home water pressure is
low. Maker 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-filters Replace pre-filters.
Fouled membrane Replace membrane and clean 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
during normal use within 1-2 weeks. If condition reoccurs
after filter 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 100 psi. A presser relief valve may be necessary.
High air pressure in tank Empty storage tank of water. Set tank air pressure to 5
psi. See previous page.
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 100 psi. 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 fill 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 previous page.
7. Water leaks from the Not properly tightened. Tighten the bowl
filter 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 filter bowl properly before
reinstalling the filter bowl.
