Complaint
Problem
Cause
Solution
Water is
effervescent
A. This can be
expected when water
is aerated under
pressure.
1. Water has been aerated by
the Iron-OX5 and Sulfur-OX3
system. As water is released to
the atmosphere, air molecules
separate from the water
molecules.
1. This natural phenomenon will
typically dissipate to the atmosphere
in a matter of seconds. If preferred,
water can be drawn and stored in an
open container prior to use (i.e. fill a
pitcher and store in the refrigerator
for cool, fresh drinking water).
Loss of
pressure
A. See complaint #1, problem A & B
Air spurting
at outside or
non-filtered
water fixtures.
A. Inlet check valve
not sealing.
1. Improper installation location.
1. See installation and operation
manual for proper location of inlet
check valve
2. Foreign material preventing
check valve from seating properly.
2. Clean or replace check valve.
3. Worn or faulty check valve.
3. Replace check valve
Air spurting
from filtered
water fixtures.
A. Reduced pressure in
distribution system.
1. Service flow demand is greater
than water supply available from
well pump system.
1. Repair or replace well pump system.
2. Water flow is restricted by
supply piping and/or water
treatment equipment.
2a. Eliminate restrictions in supply
piping to water treatment equipment
such as iron bacteria plugging the
upper diffuser assembly, etc.
2b. Install larger water treatment
system to provide less pressure drop.
Loss of
media through
drain line.
A. New filter media was
loaded dry in filter tank.
1. New filter media is shipped
in a dry condition and must be
fully wetted inside tank before
backwashing at full flow.
1. Clean drain line flow control,
control valve body, seals, spacers
and piston assemblies
B. Air passing through
filter during backwash.
1. Excess air accumulated
in filter tank.
1a.Check programmed settings to
ensure proper air draw cycle.
1b. Check that drain flow is not restricted.
2. Excess air accumulated
in filter system from water
supply or well pump.
2a. Repair well pump system.
2b. If the cause was due to temporary
loss of water main pressure; the
problem will most likely correct itself
with the return of continuous pressure.
Excessive
noise during
reconditioning
cycle .
A. Howling or
whistling noise during
reconditioning cycle.
1. Inadequate drain line size.
1. Increase drain line size
2. Drain line is vibrating against
other pipes, conduits, pipe
hangers, heat ducts, floor
joists,etc.
2. Insulate drain line, specifically at
points of contact with other materials.
