WATER SOFTENER VALVE’S AND
FUNCTION
The five cycle softening process.

Service. Raw water passes “down flow” through the resin
bed.
Backwash. The resin bed is fluidized loosening the resin
particles and removing suspended matter captured
during the service cycle.
Brine Draw. A brine solution is applied “down flow” to the
resin bed removing the hardness ions from the resin
matrix.
Slow Rinse. The brine is rinsed from the resin bed at a
low flow rate to reduce water use.
Fast Rinse. The resin is rinsed at a higher rate to remove
all brine from the bed. After the fast rinse cycle, the
softener is on Standby until returned to Service.

VALVE FUNCTION
• Service
• During the service
cycle, the raw water
enters the top of the
tank, flows through
the inlet flow
distributor, passes
through the resin
bed and exits the
tank through the
gravel support bed
and under drain
system.

VALVE FUNCTION
•Backwash
•In backwash, the raw
water enters the bottom
of the bed through the
under drain system and
exits through the top of
the tank to waste.
Backwash is up flow
and the resin bed is
fluidized.
•(10-12 Minutes)

VALVE FUNCTION
• Brining
• The resin has
limited exchange
capacity, which
must be restored
periodically
through a process
known as
regeneration.
• (15-25 Minutes)

VALVE FUNCTION
•Slow Rinse
•After the brine valve has
closed,
fresh
water
continues to flow through
the eductor. Since the
brine valve is closed, no
brine is drawn and the
flow rate is constrained by
the
eductor.
This
continues
until
the
softener sequences to the
next cycle, fast rinse.
•(40 Minute min.)

VALVE FUNCTION
• Fast Rinse
• The fast rinse cycle
is a service to waste
cycle. The inlet
water flows through
the service piping
and thru the bed but
rather than being
routed to the
softener outlet, it is
routed to drain or
waste.

Water Pressure s/b at least 25
psi (172 kPa).
Clean the nozzle and throat.
Clean the joints, union seats
and use pipe tape on the
threads to insure tight seals.
Tighten bonnet on the brine
shut-off valve.
Replace seals

Remove mineral deposits from
the flow control buttons.
Clean or replace
Clean brine tank
Re-adjust piston and motor
cam. Consult factory.

Possible Cause
Solution
a.
Distributor Broken
in tank bottom.
a.
Remove the control valve,
tank adapter, mineral and
gravel and distributor. Inspect
distributor. Distributors
should be checked before
gravel is installed. Use
caution.
b.
Unit installed
backwards
b.
Check plumbing. Inlet port on
the control valve is marked
with an arrow pointing into the
valve.

scale.
Solution
Disassemble and clean. No
water should flow out of the
solenoid valve when tubing
is disconnected and control
valve in Service position.
Clean the shaft with fine
emery paper.
Clean the port with a fine
wire or nail.
