1. Low/Slow Production:
a) Low Incoming Water Pressure: Assure a minimum of 40 PSI of incoming water pressure. Premier offers a booster pump if home water pressure is too low.  Make sure water supply is turned on and Adapt-a-Valve is fully open.
b) Crimps in tubing: Check tubing and straighten or replace as necessary.
c) Clogged pre-filters: Replace pre-filters (Typically every 6 months).
d) Fouled membrane: Replace the RO membrane (Typically every 2 to 4 years).
 
2. Milky Colored Water:
a) 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 to 2 weeks.  If condition reoccurs after a filter change, drain the storage tank 1 to 2 times.
 
3. System Constantly Running and Will Not Shut Off:
a) Low Incoming Water Pressure: Assure a minimum of 40 PSI of incoming water pressure.  Premier offers a booster pump if home water pressure is too low.  Make sure water supply is turned on and Adapt-a-Valve is fully open.
b) Crimps in tubing: Check tubing and straighten or replace as necessary.
c) High water pressure: Check incoming water pressure to make sure it does not exceed 80 psi.  A pressure regulator valve may be necessary (Available at the online store).
d) High/Low pressure in Tank: Empty storage tank of water. Using a bicycle pump or a small compressor set the storage tank air pressure to 5-7 psi. Use a Digital Air Gauge for best results.
 
4.  Noise / Water From RO Faucet Air-Gap Hole Or Noise From Drain:
Note: A gurgling sound from the air-gap/drain may be heard during the regeneration cycle.
a) Crimp in the Black 3/8” drain tube: Check the black 3/8” drain tubing to make sure it is as short and straight as possible between the RO faucet and the drain saddle.  The tube must go in a downward direction with no kinks or loops.  
b) Restriction in the Black 3/8” drain tube:  Disconnect the black 3/8” tubing from the drain saddle under the sink. Using a straightened wire coat hanger or equivalent metal wire, snake out the tubing to clear out the restriction.
 
5. Small Amount Of RO Water In The Storage Tank:
a) System starting up: Typically it will take 3-6 hours to fill the RO tank.  
Note: Low incoming water pressure and/or temperature can drastically reduce production rate.
b) High/Low pressure in Tank: Empty storage tank of water. Set tank air pressure between 5-7 psi. Use a Digital Air Gauge for best results.
c) Clogged pre-filters: Replace pre-filters.
d) Fouled membrane: Replace the RO membrane.  (Typically will last 2-4 years).
