Trouble shooting
Problem
Low/slow production
Milky colored water
Faucet Dripping
Pump short cycles
Bowl leaks at the top after
changing the filters
Pump constantly running
Checking air pressure in tank
Note: Check air pressure when tank is empty.
Step 1
Open faucet and drain the tank.
Step 2
Using a digital air gauge check the air pressure in the tank.
There should always be between 5-7 psi.
Step 3
If you have more than 7 psi release air and recheck. If you
have less than 5 psi, add air. Air can be added with a
bicycle pump.
Cause
Excessive air pressure in tank
Pump not operating
Fouled membrane
Plugged pre-filters
Crimped tubing
Angle stop or water line valve
not fully opened
Air in the system
Needs adjustment
Ball valve on tank closed
Blue tube blocked between
the tank and RO system
Faulty pressure switch
Damaged/Dry O-ring
Electrical fault
Faucet left on
Plugged pre-filters

Solution
Relieve pressure at schrader valve on tank (set
to 7 psi with the tank empty)
Wiring connection broken (plug 110 AC wall
plug back in at wall and/or reconnect the 24
VAC wire harness connectors)
Replace pump if needed
Replace membrane
Replace filters
Check tubes to make sure they are not kinked
Ensure valves are opened by turning valve
handle counter clockwise until it stops
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 changes,
drain tank 1 to 2 times.
see page 12
Open the ball valve on the top of the tank
Remove kinked/damaged section and replace if
necessary
Call for technical support
Lubricate with water soluble lubricant or replace
O-ring as necessary (Do not use Vaseline or
other petroleum based lubricants)
Call for technical support
Close faucet and let tank fill for 2 to 3 hours
Replace filters
