TROUBLE SHOOTING
Cause
Low Water Pressure
Crimps in tubing
Clogged pre-filters
Fouled membrane
Air in system
Low water pressure
Crimp in supply tube
High water pressure
High pressure in Tank
Low Pressure in Tank
Crimp or restriction
in drain line
Drain tube clogged
System starting up
Low water pressure
Too much air in tank
Check air pressure in tank

Solution
Assure a minimum of 40 psi incoming water pressure.
Premier sells a booster pump if home water pressure is
low. Make sure water supply is turned on and feed water
valve is all the way open.
Check tubing and straighten or replace as necessary.
Replace pre-filters.
Replace membrane.
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.
See #1 Above
Check tubing and straighten or repair as necessary.
Check incoming water pressure to make sure it does
not exceed 80 psi. A pressure relief valve may be
necessary.
Empty storage tank of water. Set tank air pressure
between 5-7 psi. See previous page.
Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 14.
Check tubing and straighten or repair as necessary.
Straighten all drain lines. Clear blockage. Cut off any
Excess tubing
Caused from dishwasher or garbage disposal.
Disconnect the 3/8" black line at the drain, clean the
3/8" black line out with a wire, then reconnect. Blowing
air through the line will not always remove the clog.
Normally it takes 4-6 hours to fill tank. Note: low
incoming water pressure and/or temperature can
drastically reduce production rate.
See #1 above.
Tank air pressure should be 5-7 psi when empty of water.
If below 5 psi add air or bleed if above 7 psi.
Check only when tank is empty of water.
See previous page.
Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 14.
