Run to Drain
Problem Possible Cause Solution
1. Balance Piston O- ring not seated
properly.
A. O-ring off-center
B. O-ring pinched or damaged.
A. Depress actuator several times to
try to seat the O-ring
B. Replace O-ring.
2. Bad control disc. Map side of control disc scored Replace control disc
3. Drain or control valves not seated
properly.
A. Debris trapped under the seals
B. Low water pressure (this may
prevent proper seating of seals)
A. Remove debris
B. Increase water pressure
4. Low Water Pressure (see also
“Sticking in Cycle”).
Pressure at the brine fitting lower
than 15 PSI will affect the hydraulic
movements within the softener or
filter valves and may not allow drain or
control valves to close.
Increase feed water pressure. Check
pressure before softener and after
softener. If there is a severe pressure
loss above 15 psi across the system
they may have some blockage in the
resin tanks. If filter and softener, or
two filters are installed in series, use
lockout kit.
5. The main valve piston quad rings
or level four internal quads are not
sealing.
A. Main valve quad rings may be
rolled, twisted, or damaged
B. Water may be leaking from the
main valve seat side of the level 4
to a non pressurized area on the
piston side of the level 4.
C. Seals may be damaged by chlorine
or chloramines.
A. Replace main valve piston quad
rings
B. Replace small retainer quad rings in
level 4 or replace level 4 (the piston
shafts seal against these quad rings,
and they cannot be seen without
removing the pistons).
C. Replace with blue seals for use with
chloramines.
6. Plugged signal hole or broken
non-serviceable glue seal under
ceramic disc.
Age and wear, or contamination from
poorly filtered feed water
Clean signal holes with paper clip
or compressed air; replace Level 1, if
necessary.
Salty Water
Problem Possible Cause Solution
1. Overdosing of salt. A. Brine valve set incorrectly
B. Brine valve not seating properly
C. Rubber band not removed
D. Leak in brine valve A. Set the brine valve correctly
B. Replace brine valve
C. Remove rubber band from float cup
D. Repair leak/replace brine valve.
2. Restricted drain flow. A. Drain line kinked or clogged
B. Backwash flow control restricted
C. Long drain tubing run
D. Drain tubing rises higher than 8 feet
A. Clear obstructions; ensure drain
flows smoothly and clearly
B. Clean/replace backwash flow
control
C. Shorten length of tubing or
increase size of drain tubing
D. Reduce rise to less than 8 feet
3. Low water pressure. A. Plugged prefilter
B. Pressure setting too low
C. Fouled/damaged resin bed A. Change prefilter
B. Increase feed pressure
C. Replace resin
4. Upper distributors partially
blinded (downflow units).
Foreign material or fines lodged into
the slots
Clean or replace upper distributors
