Low/Slow production
Low water pressure
Crimps in tubing
Clogged pre-filters
Fouled membrane
Assure a minimum of 40psi incoming water pressure. Watts sells a booster pump
if home water pressure is low. Make sure water supply is turned on and Adapt-A-
Valve™ is all the way open.
Check tubing and straighten or replace as necessary.
Replace pre-filters.
Replace membrane and clean flow restrictor.
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.

Low water pressure
Fouled membrane
High water pressure
High air pressure in tank
See #1 above.
Replace membrane.
Check incoming water pressure to make sure it does not exceed 100psi. A pressure
relief valve may be necessary. Empty storage tank of water. Set tank air pressure to
5psi. See previous page.
Noise from faucet or drain
Air gap faucet
Location of drain saddle
Higher capacity membrane
High water pressure
Inherent sound with air-gap faucets.
See diagram for proper location of drain saddle.
Normal with high-capacity membrane
Check incoming water pressure to make sure it does not exceed 100psi. A pressure
relief valve may be necessary.

Small amount of water in
storage tank
System just starting up
Low water pressure
Too much air in tank
Normally it takes 6-10 hours to fill tank. Note: Low pressure and/or temperature can
drastically reduce production rate.
See #1 Above
Add air if below 5psi and bleed if above 5psi. Check only when tank is empty of water.
See previous page.
Water leaks from the
filter housing
Not properly tightened.
Missing or kinked O-ring
Tighten the bowl.
Turn off the water supply. Release the pressure, remove bowl and replace the O-ring.
Make sure the O-ring is seated in the filter bowl properly before reinstalling the filter
bowl.
