TROUBLE SHOOTING
Problem
Cause
Solution
1. Low/Slow Production
Low Water Pressure
Ensure 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.
Crimps in tubing
Check tubing and straighten or replace as necessary.
Clogged pre-filters
Replace pre-filters.
Fouled membrane
Replace membrane.
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
Crimp in supply tube
Check tubing and straighten or repair as necessary.
High water pressure
Check incoming water pressure to make sure it does
not exceed 80 psi. A pressure relief valve may be
necessary.
High pressure in Tank
Empty storage tank of water. Set tank air pressure
between 5-7 psi. See previous page.
Low Pressure in Tank
Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 14.
4. Noise / Water from faucet Crimp or restriction
Check tubing and straighten or repair as necessary.
vent hole or noise from
in drain line
Straighten all drain lines. Clear blockage. Cut off any
drain.
Excess tubing
Drain tube clogged
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.
5. Small amount of water in
System starting up
Normally it takes 4-6 hours to fill tank. Note: low
storage tank
incoming water pressure and/or temperature can
drastically
reduce
production
rate.
Low water pressure
See #1 above.
Too much air in tank
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.
6. Low water flow from faucet Check air pressure in tank
Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 14.
