Troubleshooting
Problem Possible Causes Solution
1. Low / Slow Production Low Water pressure Incoming water pressure to unit must be at least 40 psi.
Old Adapt-A-Valve If you have recently installed the system, make sure any
old Adapt-A-Valves, from previous systems, have been
replaced
Crimps in tubing Check tubing and straighten or replace as necessary
Clogged pre-filters Replace pre-filters
Fouled Membrane Replace Membrane.
Clogged Post-Carbon Filter Replace Post-Carbon filter
2. Milky colored water Air in system Air in the system is a normal occurance with the initial
start-up after RO installation or filter replacement. This
will disappear during normal use within 1-2 weeks. If it
continues, check incoming water.
3. System is constantly running. Crimps in tubing Check tubing and straighten or replace as necessary
Clogged pre-filters Replace prefilters
Fouled Membrane Replace Membrane.
Other Turn off the valve at the top of the tank and check water
production from faucet. The system should produce at
least 3-4 ounces (89-118 mL) per minute with the tank
off. If it is producing less, check for clogged pre-filters or
a fouled membrane.
4. Small amount of water in storage
tank
System is starting up Normally it takes 4-6 hours to fill tank. Note: low storage
tank pressure, incoming water pressure, and/or tem-
perature can drastically reduce production rate.
Low water pressure See Item 1
Air pressure in tank is too high Repressurize Tank - See Page 9
Low air pressure in tank Repressurize Tank - See Page 9
5. Low flow from faucet. Low air pressure in tank Repressurize Tank - See Page 9
