More Troubleshooting Tips

Brine Solution Not Being Sucked In During Regeneration

Most problems occur when the 5900e is not drawing in the brine. Make sure the injector is drawing in the
brine:
1. Remove the brine tank tubing where it enters the 5900e control valve.
2. Initiate a backwash and skip to the Brine Cycle by following the steps below:
A. Starting delayed extra cycle
-If days remaining is not already at 1 press and hold the Set/Change button.
-After 3 seconds the days remaining display will read 1
-Regeneration cycle will be initiated at the next designated regeneration time
B. Starting Immediate Extra Cycle - First, complete above delayed cycle steps
-With days remaining at 1 press and hold the Set/Change button
-After 3 seconds the regeneration cycle will begin.
C. Fast Cycling Through Regeneration
-First complete above immediate cycle steps
-Press and hold the Set/Change button
-After 3 seconds the valve will start to advance to the next step
where it is supposed to suck in the brine solution.
3. If it is sucking strongly, check the brine tank float inside the brine well and make sure there are no
rubber bands around it, and that is free of obstructions. In some cases it may need to be replaced or
cleaned, if there is suction at the control valve, but no brine is being drawn in.
4. If there is NO suction at the control valve port where you removed the brine line tubing, then the
injector should be cleaned.
5. If the injector has been cleaned and there is still no suction check to make sure there is obstruction in
the backwash line; that the backwash line does not go up and over the Tannin filter more than several
feet (which causes pressure loss and the injector not to work correctly); finally check to make sure there
is enough pressure. If possible increase your water pressure to the Tannin filter from your well pump
and see if a slightly increased pressure makes the injector work. We recommend a minimum 30 PSI but
it does work better if there is 40 to 50 minimum PSI.

System Not Backwashing Adequately

The other main problem that may occur is if you do not have enough backwash flow rate to properly clean
the Tannin filter. You can verify the backwash flow rate by running the drain line into a bucket and timing it
when the 5900 is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should have 2.0 gallons per minute
and a 2.5 cubic foot system should have 4.0 gallons per minute of backwash.
