PROBABLE CAUSE

CURE

LOW WATER VOLUME

1       Feed valve shut off

1       Open feed valve

2       Low feed pressure

2       Ensure source feed pressure is at a minimum of 40psi. Re-place booster pump or 24 volt DC transformer

3       Pre-filter cartridge clogged

3       Replace pre-filter

4       Clogged shut off valve

4       Clean or replace

5       Product check valve stuck

5       Clean or replace

6       Storage tank under/over pressurized

6       Tank should maintain 15 psi. when empty.

7       System overuse

7       Demand exceeds system volume-increase holding tank and membrane size capacity

8     Storage tank ball valve is turned off

8       Open ball valve.

HIGH TDS IN PRODUCT

9       Membrane expended

9       Replace membrane

WATER

10    Membrane bacteria fouled

10    Feed water must be chlorinated

11    Clogged pre-filters

11    Replace

12    Low brine flow to drain

12    Replace flow restrictor

13    Low feed pressure

13    Ensure source feed pressure at a min. of 40psi.  Replace booster pump or 24VDC transformer

14    Feed water (TDS) increase

14    Determine TDS % rejection; replace membrane

BAD TASTING WATER

15    Post filter exhausted

15    Replace post-filter cartridge

16    Depleted membrane

16    Check TDS % rejection-replace membrane.

17    Tank & system contaminated

17    Replace pre & post filters, and sterilize system

18    New post filter not flushed completely

18    Flush 1 full tank of pure water through system.

19    1st daily usage

19    Allow water to run for 30 seconds before using.

20    Feed water (TDS) increase

20    Change filters more frequently.

CLOUDY WATER

21    As feed water containing dissolved air passes through the RO system it becomes concentrated

21    Will change as (feed water) air levels change.  Allowing product water to stand still, will allow air to dissipate from product water.

CLOUDY ICE CUBES

22    See #21

22    See #21

23    Increase in product (TDS)

23    Change filters

24    Ice cube configuration- as ice cubes dissolve; some shapes take on more air than others do.  The larger & squarer shaped cubes are the cleanest.

24    Change ice cube mold, avoid small rounded cubes.

FITTING LEAKS IN GENERAL

25    Close the Saddle Tapping Valve (feed water) and relieve pressure before disconnecting any fitting.  Tighten compression nuts or refer to the respective assembly drawing for proper assembly.  If pipe threads are leaking, remove and re-tape with Teflon tape.

FAUCET LEAKS OR DRIPS

26    Leaks from spout.

26    Adjust Faucet by turning the tee bar just below handle to provide a small amount of free play in handle when shut off.

26    O-rings are bad.  Repair or replace faucet.

27    Leaks from base of delivery tube.

27    O-ring is bad.  Replace O-ring.

28    Leaks from beneath the handle.

28    O-rings are bad.  Repair or replace the faucet.
