Problem
Possible Cause
Solution
8. Hard or untreated water is being delivered
a. Bypass valve is open or faulty
a. Fully close bypass valve or replace
b. Media is exhausted due to high water
usage
b. Check program settings or diagnostics for
abnormal water usage
c. Meter not registering
c. Remove meter and check for rotation or
foreign material
d. Water quality fluctuation
d. Test water and adjust program values
accordingly
e. No regenerant or low level of regenerant in
regenerant tank
e. Add proper regenerant to tank
f. Control fails to draw in regenerant
f. Refer to Trouble Shooting Guide number 12
g. Insufficient regenerant level in regenerant
tank
g. Check refill setting in programming. Check
refill flow control for restrictions or debris
and clean or replace
h. Damaged seal/stack assembly
h. Replace seal/stack assembly
i. Control valve body type and piston type mix
matched
i. Verify proper control valve body type and
piston type match
j. Fouled media bed
j. Replace media bed
9. Control valve uses too much regenerant
a. Improper refill setting
a. Check refill setting
b. Improper program settings
b. Check program setting to make sure
they are specific to the water quality and
application needs
c. Control valve regenerates frequently
c. Check for leaking fixtures that may
be exhausting capacity or system is
undersized
10. Residual regenerant being delivered to
service
a. Low water pressure
a. Check incoming water pressure – water
pressure must remain at minimum of 25
psi
b. Incorrect injector size
b. Replace injector with correct size for the
application
c. Restricted drain line
c. Check drain line for restrictions or debris
and clean
11. Excessive water in regenerant tank
a. Improper program settings
a. Check refill setting
b. Plugged injector
b. Remove injector and clean or replace
c. Drive cap assembly not tightened in
properly
c. Re-tighten the drive cap assembly
d. Damaged seal/ stack assembly
d. Replace seal/ stack
e. Restricted or kinked drain line
e. Check drain line for restrictions or debris
and or un-kink drain line
f. Plugged backwash flow controller
f. Remove backwash flow controller and
clean or replace
g. Missing refill flow controller
g. Replace refill flow controller
12. Control valve fails to draw in regenerant
a. Injector is plugged
a. Remove injector and clean or replace
b. Faulty regenerant piston
b. Replace regenerant piston
c. Regenerant line connection leak
c. Inspect regenerant line for air leak
d. Drain line restriction or debris cause
excess back pressure
d. Inspect drain line and clean to correct
restriction
e. Drain line too long or too high
e. Shorten length and or height
f. Low water pressure
f. Check incoming water pressure – water
pressure must remain at minimum of 25
psi
